Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) viii CHAPTER 1 Cisco Unified Intelligence Center Overview Cisco Unified Intelligence Center is a comprehensive, end-to-end reporting solution, built using Web 2.0 frameworks. It is designed to make the task of creating reports and managing disparate data sources easier for the customer. The Unified Intelligence Center reporting platform is intended to be a common tool with a consistent user interface that can access data across multiple Cisco Systems product families. Unified Intelligence Center reporting features include multi-user support, customized reports, Live Data reports, security, multiple display formats, web accessibility, support for permalinks, and Web 2.0-like mash-up support to display data from multiple sources on a single dashboard. These features make Unified Intelligence Center a valuable tool in the Information Technology arsenal of any organization and position it as a drop-in replacement or solution for most reporting requirements. Unified Intelligence Center Deployments Unified Intelligence Center is installed as part of Unified Contact Center Express, and is configured to be co-resident in Unified Contact Center Express deployments. In Packaged Contact Center Enterprise Solution deployments, Unified Intelligence Center is configured as a standalone Virtual Machine . In Unified Contact Center Enterprise deployments, Unified Intelligence Center is installed as a standalone server or as a cluster of a maximum of eight server nodes. Note Unified Intelligence Center is supported only in Virtual Machine environments from release 10.0(1) . Unified Intelligence Center and Live Data Unified Intelligence Center supports Live Data reports for Unified CCX and Packaged CCE deployments from release 10.0(1) and in Unified CCE deployments from release 11.0(1). Live Data reports are based on an asynchronous event stream from a Live Data data source and are updated in real-time as and when the events are received on the client browser where the Live Data report is running. Two types of clients are supported for Live Data reports - within the Unified Intelligence Center web interface, and as a Live Data gadget on the Finesse desktop. Cisco Unified Intelligence Center offers both a web-based Reporting application and an Administration interface. The Cisco Unified Intelligence Center Reporting Node runs on the members. The Unified Intelligence Center Administration runs on the Controller. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 1 Cisco Unified Intelligence Center Overview Feature List Release 11.0(1) supports stock reports for Cisco Unified Contact Center Enterprise (Unified CCE), Cisco Unified Contact Center Express (Unified CCX) and Cisco Packaged Contact Center Enterprise (Packaged CCE), and accepts the import of reports designed for use with Cisco Unified Customer Voice Portal (Unified CVP). This chapter contains the following topics: • Feature List, page 2 • Licensing, page 3 • Security, page 3 • Throttling for Historical and Real-Time Reports, page 4 Feature List This section includes a basic feature list for Unified Intelligence Center Reporting. For a comprehensive list of the report templates, their features, and their use, see Cisco Unified Intelligence Center User Guide and the Cisco Unified Intelligence Center Report Customization Guide. Reporting Capabilities Live Data reports Authenticate secured permalinks Variable parameters in permalinks Performance optimization in Internet Explorer for loading collection values Create new entities and to modify existing entities in a category Powerful grid presentations of reports with sorting and grouping Grouping is not supported for Live Data reports.

Multi-user support Note Customized dashboards and custom reports Report scheduler Detailed security levels and support for LDAP/local database authentication Import and export of report XML files Export of grid reports to Microsoft Excel Email reports in PDF format Export reports in CSV format to a remote location through SFTP Reporting across various time zones Report Infrastructure Multiple language support Clustered deployment Management support through Simple Network Management Protocol (SNMP), Java Management Extensions (JMX), and Cisco Prime Collaboration. Audit Trail of changes Licensing Unified Intelligence Center deployments from release 10.0(1) are supported only in VM environments and licenses are based on the Licensing MAC. For more information about obtaining and installing licenses, see the Installation and Upgrade Guide for Cisco Unified Intelligence Center. For cluster deployment, the license file specifies the maximum number of Unified Intelligence Center servers that the cluster can support. Security Unified Intelligence Center supports only HTTPS access by default. HTTP access can be turned on using the CLI command "set cuic properties http-enabled" . For more information, see the Administration Console User Guide for Cisco Unified Intelligence Center at: http://www.cisco.com/en/US/products/ps9755/prod_ maintenance_guides_list.html. This mode is not supported due to the security vulnerabilities it exposes. User authentication on logging in is performed using one of the following 2 mechanisms: • LDAP based authentication • Application-specific authentication based on the local Unified Intelligence Center database Unified Intelligence Center defines a set of roles that determines the actions a user with the corresponding role or roles can perform. Users with Security Administrator role can set roles and access permissions for all other users. Permissions determine the set of resources a user can access and operate on. Unified Intelligence Center defines two levels of permissions - execute and write. Execute permissions on a resource enables an Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 3 Cisco Unified Intelligence Center Overview Internal Firewall user to view and operate on the resource, while Write permissions on a resource enables a user to modify and delete the resource. An owner of a resource (that is, the user who creates a resource) always has write permissions on the resource. Unified Intelligence Center uses a fixed identity configured as part of each data source to access the underlying data sources irrespective of the current logged-in user. Unified Intelligence Center supports Unified CCE user integration, where Unified CCE supervisors can be imported into the Unified Intelligence Center application with specific, automatically-assigned roles. Internal Firewall The Unified Intelligence Center nodes are shipped with built-in fire walls (IpTables). For more information about Internal Firewall, see the Cisco Unified Intelligence Center TCP and UDP Port Usage guide on http://www.cisco.com/en/US/products/ps9755/prod_maintenance_guides_list.html. Firewall Integration in a Wide Area Network Data source servers that are deployed over WAN links are likely to encounter firewalls. Firewall requirements for supported databases are as follows: • Microsoft SQL Server Default instances of SQL Server listen on TCP port 1433. Named instances, however, dynamically assign an unused TCP port number the first time the instance starts. The named instance can also dynamically change its TCP port address on a later startup if another application is using the original TCP port number. Named instances should therefore be assigned a static port using the SQL Server Configuration Manager. Microsoft SQL Server uses UDP port 1434 to establish communication links from applications for its SQL Server browser service. Configure the firewall to forward all requests for UDP port 1434 on the database server address. For more information, see this article on the MSDN Configuring the Windows Firewall to Allow SQL Server Access SQL server firewall configuration guide. • IBM Informix IDS The Informix IDS server listens on a single incoming TCP port for incoming database connections. For more information, see the Cisco Unified Intelligence Center TCP and UDP Port Usage guide on http:// www.cisco.com/en/US/products/ps9755/prod_maintenance_guides_list.html. For more information, see the IDS communication guides. Throttling for Historical and Real-Time Reports The Unified Intelligence Center throttling mechanism prevents servers from freezing or encountering an Out-of-Memory situation when they are pushed beyond their limits. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 4 Cisco Unified Intelligence Center Overview Throttling for Historical and Real-Time Reports Note Throttling is not the same as ensuring good quality of service. If a Unified Intelligence Center deployment is being overused, the level of service may degrade substantially before the throttling mechanism is activated. Memory is the resource that is actively throttled by the Unified Intelligence Center application. Processing report data accounts for the majority of memory consumption in Unified Intelligence Center. For that reason, memory throttling focuses on controlling memory consumption due to reporting activity. The report row is the basic unit used to measure the amount of reporting activity. Using report rows as the basic unit to measure reporting activity gives flexibility to users. A user can decide to run a few big reports or many small ones and the throttling mechanism are equally effective without requiring any tuning. Report rows are counted only as they are loaded into memory, so no guesses are made as to report size. Test results using the row sizes of the installed stock reports indicate that 2 KB is a conservative estimate for the size of a report row. If each report row is 2 KB in size, then 250,000 is the maximum number of report rows that a Unified Intelligence Center server allows into memory before the server encounters an Out-of-Memory situation. To enforce this limit, each Unified Intelligence Center keeps count of the number of report rows currently loaded into memory. That count is checked by all reporting operations to determine if additional report rows can be loaded into memory. If an operation cannot proceed because the number of concurrent rows in memory has reached the maximum value, the operation fails and an error is displayed to the user. What happens if the limits are exceeded? Report rows are loaded into memory when the data is being fetched from the data source and when it is being prepared to be sent to the browsers. Either of these operations can fail if the maximum number of concurrent report rows in memory is exceeded: • If a violation happens while Unified Intelligence Center is reading data from a data source, the report execution aborts and the report is marked as failed. Unified Intelligence Center does not take partial results–the system either reads all the data that a user requests or marks the report as failed and stores none of the data. • If a violation occurs while Unified Intelligence Center is in the process of preparing the HTTPS response for a browser (HTML of a grid, JSON string of a gauge, or XML of a chart), the request to display the data is rejected and the user sees an error message that says the report cannot be rendered because the server is low on resources. Note Do not use the throttling mechanism for any sizing purposes. The throttling mechanism is designed to prevent an Out-of-Memory situation and hence this mechanism does not ensure a good quality of service to the users. Always use the sizing calculator to determine your reporting sizing needs. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 5 Cisco Unified Intelligence Center Overview Throttling for Historical and Real-Time Reports Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 6 CHAPTER 2 Architecture Unified Intelligence Center is a clustered, web-based reporting application that can extract and display data from external data sources using Structured Query language (SQL) statements and Live Data event streams. This chapter contains the following topics: • Platform, page 7 • Browser Clients, page 8 • Unified Intelligence Center Administration, page 8 • Cisco Unified Intelligence Center Reporting Node, page 9 • Cluster Support, page 9 • Data Source Server, page 13 • Local and Wide Area Networks, page 15 Platform Unified Intelligence Center is supported as an appliance and is packaged with its complete environment, including its base platform—the Cisco Unified Communications Manager Operating System (Unified Communications Manager OS). The Unified Communications Manager OS actively discourages user modifications or access to the underlying components except through supported administrative interfaces. Unified Intelligence Center is shipped co-resident with Cisco Unified Contact Center Express application from release 9.0(1). This is a seamless integration of the two applications with support for single sign-on across the two applications. Unified Intelligence Center supports Unified CCX historical reports and Live Data reports. Unified Intelligence Center nodes are deployed in standalone VMs in Packaged CCE and Unified CCE deployments. Unified Intelligence Center supports Historical, Real-time, and Live Data reports with Packaged CCE solution and with Unified CCE. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 7 Architecture Browser Clients Browser Clients The Unified Intelligence Center application is designed to be accessed over Hypertext Transfer Protocol (HTTPS) from web browser clients having JavaScript support. After logging in, HTTPS is used for all other pages. The Internet Explorer and Mozilla Firefox clients are supported in this release. For more information, see the Compatibility Matrix wiki Unified CCE and Unified CCX. Unified Intelligence Center Administration The Unified Intelligence Center Administration server is the administrative and management component for Unified Intelligence Center and provides operations, administration, maintenance, and provisioning (OAMP) functions. The Administration is the primary interface for configuring Unified Intelligence Center-specific application settings for a cluster, as well as provisioning devices in a cluster. The Administration works in conjunction with the other Unified Communications Manager OS web applications to manage a Unified Communications Manager OS device. Administration is a mandatory component and is deployed and accessible only on the primary (controller) node in the cluster. If you install only a single (standalone) node, that node is the controller and has both the Administration and the Reporting applications. The Administration is a web-based application and requires System Application User or Super User login through HTTPS. Use the Administration to: • Configure reporting nodes in the cluster • Manage licensing • Download the Real Time Monitoring Tool (RTMT) • Configure Super User and policies • Configure security-related settings such as LDAP configuration • Manage serviceability settings such as trace levels and log file size, which are used for troubleshooting and debugging • Configure SMTP • Start or stop the Unified Intelligence Center web reporting application on other nodes in the cluster • Synchronize (integrate) Unified CCE users Note Platform management applications for managing system-level functions such as network options, certificates, upgrades, and SNMP and Alert settings are not handled by the Unified Intelligence Center Administration application. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 8 Architecture Cisco Unified Intelligence Center Reporting Node Note Access three Cisco Unified Communications Manager tools (Cisco Unified OS Administration, Cisco Unified Serviceability, and Disaster Recovery System) from any node. For information about these platform management applications, see the Administration Console User Guide for Cisco Unified Intelligence Center. Cisco Unified Intelligence Center Reporting Node The reporting node is the core of Unified Intelligence Center and contains all the features for reporting. Deploy a standalone single reporting node on a controller node or on one controller node with up to seven reporting member nodes in a cluster. The following software components are deployed in the reporting node: • Firewall. • Web Server that runs the Unified Intelligence Center application. • JAVA services and JSP pages that translate the web requests into HTML. • Unified Intelligence Center Database (Informix) with replication support within the cluster. • The Administration (OAMP) application (when the reporting node is also the only node of the cluster). Cluster Support When the number of concurrent logins and reporting needs exceed the capacity of a single (controller) server, deploy Unified Intelligence Center in a clustered mode. In this mode, multiple member (reporting) nodes present a unified application to the user and allow a consistent, shared configuration across the controller and all member nodes. Multiple nodes bring better scalability to the reporting infrastructure than using a single, vertically-scaled reporting server. Cluster support also presents an opportunity to gradually scale the solution, depending on the needs of the deployment. Clustering in Unified Intelligence Center is made possible by the IBM Informix Unified Intelligence Center database, which serves as the backend data store for the Unified Intelligence Center reporting application. Enterprise Replication database connects and synchronizes the multiple nodes participating in a cluster. Administrative changes, configuration updates, and so forth are communicated throughout the cluster and all users are presented with a common interface object, irrespective of the node used to serve their requests and actions. In addition, nodes communicate with each other directly by using IP multicast, which happens independently of database replication. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 9 Architecture WAN Overview Multicast group IP address values can be between 224.0.0.0 and 239.255.255.255. Default value is 224.2.2.3 Figure 1: Database Replication WAN Overview The Unified Intelligence Center cluster is a group of independent nodes, each of which has a replicated database that is kept in sync with the other nodes in the cluster. With Unified Intelligence Center Release 8.0.2 (and later), you can distribute the Unified Intelligence Center cluster over the WAN. When participating in a cluster, either over a LAN or WAN, the configuration objects created on one node automatically replicate to other nodes. This chapter describes the sizing considerations made when considering clustering over the WAN. In general, size the WAN so that it supports the customer-expected performance characteristics. Consider the following network characteristics: • Bandwidth: is a measure of the amount of data that can be sent per second. • Duplex: is a measure of how data can be transmitted. Full duplex indicates traffic can be transmitted at full bandwidth speed in both directions. Unified Intelligence Center requires a full duplex WAN connection. • Latency: is a measure of the time it takes for a data packet to propagate from one side of the WAN to the other. For Unified Intelligence Center, this must be 100 ms or less, which leads to a Round Trip Time (RTT) of 200 ms or less. • Jitter: is a measure of how much variance there is with respect to latency. Cisco expects that network jitter is minimized and that the latency accounts for all the jitter. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 10 Architecture WAN Overview • Loss: (sometimes referred to packet loss) is a measure of how much data can be lost or dropped. This should be minimized and it is expected that loss is at or near 0%. Anything else leads to retransmissions and effective loss of bandwidth (as the same data is being retransmitted). • Duplication: is a measure of how much data can be duplicated. This should be minimized and it is expected that duplication is at or near 0%. Anything else leads to retransmissions and effective loss of bandwidth (as the same data is being retransmitted). • Corruption: is a measure of how much data can be corrupted. This should be minimized and it is expected that corruption is at or near 0%. Anything else leads to retransmissions and effective loss of bandwidth (as the same data is being retransmitted). As previously stated, each Unified Intelligence Center node is independent of every other node and all database updates (that is, configuration data) are replicated as to all other nodes. When the Unified Intelligence Center cluster is running over the WAN, it should be noted that this replication utilizes the WAN connection and therefore is a function of the network characteristics. As an object is created on one node, it will be instantly available users on that node, but may take a few seconds before the object can replicate to other nodes (see the following for time estimates based on object size). The only objects that are replicated are configuration objects. Configuration objects include the following: • Data Sources: encapsulates configuration data for each data source object • Dashboard: encapsulates configuration data for dashboard object • Report Definition Filter: encapsulates configuration data for each report definition filter (Note: Running a report with an initial or new filter causes replication of the filter object, but refreshing a report has no impact on replication.) • Report Definitions: encapsulates report definition configuration information • Reports: encapsulates a report object, which points to a report definition and corresponding views • Report Types: encapsulates configuration information for the type of report (grid, chart, gauge) • Views: encapsulates column names, groupings, hidden fields • Users: encapsulates a user • Categories: encapsulates configuration information for categorization of reports, report definitions, and dashboards • Value Lists: encapsulates configuration information for the value list • Collections: encapsulates configuration information for a collection that includes its values • DataSets (from Scheduled Reports): encapsulates the data set for a scheduled report. The data set information is replicated to all nodes only for scheduled reports that are placed on dashboard. In general, Cisco expects that most users configure the Unified Intelligence Center system with a set of commonly accessed reports and run these reports periodically. In addition, Cisco expects that users create new objects (for example, reports), but this should occur less frequently. Any configuration object that is modified or created needs to be replicated and will be replicated as quickly as possible, but since we are expecting users to be modifying or creating objects less frequently than executing or accessing an object, this should minimize the need for large amounts of WAN bandwidth. Because every node requires a connection to every other node, replication is estimated by assuming that each node receives a portion or channel of the WAN bandwidth, which is a function of the number of nodes in Site Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 11 Architecture WAN Overview A and the number of nodes in Site B. Or more specifically, the WAN bandwidth requirements differ depending on how the cluster is setup. For more information, see Bandwidth and Performance Requirements, on page 27. Organizing Sites Because the maximum size of a cluster supported by Unified Intelligence Center is eight nodes, it is impossible to have a fully redundant clustering solution unless each site is at most four nodes. As qualified, each Unified Intelligence Center supports up to 200 users given the Reporting Standard Profile defined in Chapter 4. In addition, only the Unified Intelligence Center Primary node can provide the following services: • OAMP • Scheduler The Primary node must be located at the customer's primary site (as these services will be unavailable during a failover situation). Furthermore, it is crucial that you back up the Primary node periodically in either a LAN or WAN environment. Failures Each Unified Intelligence Center node buffers replication data to send to other nodes in the cluster. When communication is lost with other nodes in the cluster (or a node fails) then the data is queued until contact with the other node or nodes is restored. Each node continues to work independently even during connectivity failure--it just does not have access to objects created or modified on other nodes. Even though the queue is quite large (1600 MB)-- it is not unlimited, therefore, the queue fills up during a prolonged failure situation. As the buffer fills and starts to reach capacity, an alarm is sent (CiscoAlarm30) notifying administrators of the potential buffer exhaustion condition. If connectivity is restored before the buffer is filled, then it synchronizes at a rate proportional to the amount of data in the buffer and the connection bandwidth. If connectivity is not restored before the buffer fills, then replication is reset. Resetting replication allows the node to continue running reports and working independently. If the node is a secondary node then it requires full synchronization with the primary node (primary database backup and restore on secondary node) when connectivity with the primary node is restored. If replication is reset, then anything created/modified on the secondary node is rolled-back to the state of the primary database. If the primary node fails, you have to re-install and revert to a saved backup. Make sure that you back up the primary node periodically so that no data is lost. It is very important in WAN environments to periodically back up the Primary node. Prolonged WAN outage, failure of primary node, and failure to perform recommended backups could result in a cluster that must be reinstalled or else there could be data lost. If connectivity is restored before the buffer fills, then all data is automatically replicated. Depending upon the connection between the nodes and the amount of data that has accumulated, it may take some time for the nodes to fully synchronize. At any time, administrative users can view the status replication (including the number of bytes in the replication queue) using the CLI command: utils dbreplication runtimestate. For more information, see the Administration Console User Guide for Cisco Unified Intelligence Center. Configuring WAN After you install and configure all systems, restart each system. This allows clustering to synchronize and to merge on network partitions. This only needs to be done the first time after configuring a new node. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 12 Architecture Database Replication in the Cluster Database Replication in the Cluster The Unified Communications Manager OS installs Informix as part of the base platform installation. Installation-specific scripts create the Unified Intelligence Center application database on each reporting node and set up the enterprise replication among participating nodes. The Unified Intelligence Center database is the main data store for the Unified Intelligence Center reporting web application. It holds configuration information relating to users, reports, and user access rights for each node in the cluster. Unified Intelligence Center uses the update-anywhere enterprise replication model based on a topology of Fully Connected Database servers. Each database server has connection to all other database servers. Data can be transferred from any machine to all others. Data is replicated immediately, as soon as changes are made. Changes that are apparent in the User Interface (such as the addition or deletion of a dashboard or a change to a report definition) are evident across all devices when the page is refreshed, provided that all devices in the cluster have all the required network connections and CPU power to do the processing. An automated daily purge that runs every day at midnight takes care of database maintenance activities. The purge schedule can be controlled or changed through the command line interface. Purge is the only local database maintenance apart from the backup that is required for local Unified Intelligence Center databases. Data Source Server Unified Intelligence Center supports two types of data sources: • SQL based data sources for Real-time and Historical reports. • Streaming data sources for Live Data reports. The SQL-based data source contains the database and the schema that store the reporting data that populate the reports. This must be a valid JDBC compliant database. Unified Intelligence Center is currently validated with SQL server 2008, 2012 and 2014, and Informix 12.10 FC3 database versions. Note Set SQL Server Authentication to SQL Server and Windows Authentication mode. This release does not support Windows Authentication to a SQL Server database. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 13 Architecture Nodes Mapped to Multiple Databases These data source servers are supported for the Packaged CCE and Unified CCE reports, importable Unified CVP, Finesse, Social Miner, Enterprise Chat and Email reports, and Unified CCX historical reports in co-resident mode. Figure 2: Unified Intelligence Center Architecture Nodes Mapped to Multiple Databases The number of data sources that you must deploy for Unified Intelligence Center depends on the number of concurrent reports to be supported and the number of concurrent logins. You can distribute the reporting load to several Unified CCE AW-HDS databases using the command line interface and conventional name resolution. If there is a need to direct a specific member node to a database host other than the one in configured on the data sources interface, you can use the set cuic-properties host-to-ip command to resolve the data source name differently on each node. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 14 Architecture Local and Wide Area Networks You can direct any given reporting member node to a specific Unified CCE database. Figure 3: Nodes Mapped to Multiple Databases Local and Wide Area Networks Data Sources have been qualified over local area networks (LAN) and wide area networks (WAN). Note Distributing data source servers over a WAN can increase the report execution times, depending on the latencies and traffic conditions over the WAN.

Each model addresses scalability of the solution. The exact model that must be employed at different sites depends upon on the number of clients to be supported and, to a lesser extent, on the amount of data being reported. For more information about sizing calculations, see Sizing Parameters. This chapter contains the following topics: • Cisco Unified Intelligence Center Deployment, page 17 • Live Data Architecture and Deployment, page 19 • Cisco Packaged CCE and Cisco Unified CCE Deployments, page 22 • Cisco Unified Customer Voice Portal Deployment, page 25 Cisco Unified Intelligence Center Deployment Unified Intelligence Center 11.0(1) supports the deployment model of one to eight servers clustered. The deployment model supported by Unified Intelligence Center consists of a Unified Intelligence Center cluster that communicates directly with the database running on the data source server. Unified Intelligence Center Deployment Model The standard model includes the following components: • One or two Unified Intelligence Center reporting (member) nodes in a cluster • Real-time and historical data source or sources • Other data sources (optional) • Live Data sources This deployment model consists of a Unified Intelligence Center cluster that communicates directly with the database running on the data source for real-time and historical reports, based on report requests issued by web clients. Live Data reports are updated by a Live Data event stream that originates from the data source. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 17 Deployment Models Unified Intelligence Center Deployment Model Data flow: • The web client makes an HTTPS request for a Unified Intelligence Center page/report • The web request is handled by the web server on the Unified Intelligence Center reporting node • When a report is requested, the data is pulled from the data source server, which supplies the actual data for both historical and real-time reports. For more information on Live Data control and data flows, see the Live Data Serviceability Guide http://www.cisco.com/c/en/us/support/customer-collaboration/ unified-contact-center-enterprise/tsd-products-support-series-home.html. Figure 4: Unified Intelligence Center Deployment Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 18 Deployment Models Live Data Architecture and Deployment Live Data Architecture and Deployment The following diagram shows the generic system reporting architecture for real-time reports. Figure 5: System Architecture - Unified Intelligence Center Live Data Reports in Unified CCE and Unified CCX Deployments Note Ensure that the Unified Intelligence Center and data source servers in any deployment are in synch with the same NTP server. Unified CCE and Unified CCX publish real-time updates of changes in agent, skillgroup, and calltype state through Websockets (Live Data Service in Figure 5). Unified Intelligence Center web application has reports which can run in the browser and consume these messages directly from Live Data Services and display the updates in realtime. While the diagram depicts a single Unified Intelligence Center node that connects to the Live Data Service and servicing a single browser client. In actual deployments, a single Unified Intelligence Center node can service multiple browser clients, each running multiple instances of various reports. In addition to displaying Live Data reports in the Unified Intelligence Center Report Viewer, an important component of the Unified Intelligence Center 11.0(1) solution release is to display the Live Data reports in gadgets on the Agent and Supervisor Finesse desktop. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 19 Deployment Models Cisco Unified Contact Center Express Architecture Deployment Cisco Unified Contact Center Express Architecture Deployment In Unified CCX deployments, both Unified Intelligence Center and Finesse are coresident on the same server along with Unified CCX. Figure 6: System Architecture - Cisco Unified Contact Center Express The above diagram depicts the HA configuration of Unified CCX, where the primary node, by default, is the master, and the secondary node is the warm standby. Historical reports are not available as gadgets in 11.0(1) Solution release. Websocket Server - Only one instance of Websocket server is installed in the Unified CCX node. Live Data gadget on Finesse desktop - The live-data gadget is loaded on the Finesse desktop only after an Agent or Supervisor has logged in and the Finesse container is initialized. One of the reporting gadgets set up the websocket tunnel. This common tunnel is shared by all the Unified Intelligence Center gadgets. Live Data report in Unified Intelligence Center Report Viewer or through a native permalink - All the Javascript libraries are required to create the Websocket tunnel and the OpenAjaxHub in the browser are loaded as part of the web page. A Websocket tunnel is then created from the client window to the Websocket server, and shared by all the Live Data reports executed in the client window. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 20 Deployment Models Packaged CCE and Unified CCE Architecture Diagram The system diagram for Live Data gadgets embedded in the Finesse desktop and for Live Data reports running in the Unified Intelligence Center Report Viewer is shown below. Figure 7: Cisco Unified Contact Center Express - Live Data Gadgets Packaged CCE and Unified CCE Architecture Diagram In Packaged CCE, each Unified Intelligence Center node in the deployment hosts an instance of Live Data Service to serve Live Data clients logged in to that node. In Unified CCE, the Live Data Service has its own virtual machines. Live Data reports running in the Unified Intelligence Center Report Viewer and through permalink access uses a Websocket tunnel created from the client to the Websocket server instance on the Live Data Service. Finesse server is hosted in a separate virtual machine. Live Data reports running in gadgets on the Finesse desktop result in the creation of a Websocket tunnel from the Finesse desktop parent container to one of the Live Data Services. The Websocket tunnel to the Live Data server is initiated during loading of the Live Data gadget into the Finesse container. Live Data reports in Unified Intelligence Center 11.0(1) does automatic failover in the event of a failed Websocket connection to the currently connected Live Data node. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 21 Deployment Models Cisco Packaged CCE and Cisco Unified CCE Deployments The diagram for Live Data gadgets on the Finesse desktop and for Live Data reports in the Unified Intelligence Center Report Viewer in Packaged CCE and Unified CCE deployment is shown below: Figure 8: Packaged CCE and Unified CCE Live Data Reports Cisco Packaged CCE and Cisco Unified CCE Deployments Packaged CCE and Unified CCE are integral components of the Cisco Unified Communications system and delivers a comprehensive solution that provides intelligent routing and logging functionality and call treatment. The data generated in databases is maintained in the Administration and Data Server, formerly called the Distributor Admin Workstation (AW). Administration and Data Server as Unified Intelligence Center Data Source The Administration and Data Server holds the database used as the Unified Intelligence Center data source for Unified Intelligence Center stock reports. Packaged CCE and Unified CCE can support multiple Administration and Data Servers. Packaged CCE and Unified CCE introduced a new set of options based on deployment size: • For small or medium deployments, select Administration Server and Historical Data Server (AW-HDS). This is the selection for Unified Intelligence Center data feed. • For large deployments, select Administration Server, Historical Data Server, and Detail Data Server (AW-HDS-DDS). Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 22 Deployment Models Administration and Data Server as Unified Intelligence Center Data Source These selections are documented in the Cisco Unified Contact Center Enterprise Solution Reference Network Design (SRND). Note Unified Intelligence Center uses AW/HDS as a data source for standard historical reports and AW/HDS or AW as a data source for standard real-time reports. In all cases, the database on the Administration and Data Server and the views inside it are used as the tables for the data source queries run from Unified Intelligence Center. This makes it unnecessary to maintain additional database network connections to multiple databases from the Unified Intelligence Center, and all the data pertaining to Packaged CCE and Unified CCE can be referenced by single data source. The Unified Intelligence Center installation adds two data sources to the reporting (member) nodes: • The Packaged CCE and Unified CCE Historical data source, which support the Unified ICM/CC stocks historical reports, and Packaged CCE and Unified CCE User Integration. • The Packaged CCE and Unified CCE Realtime data source–-This data source is added by default to support the Unified ICM/CC stock realtime reports. Configure the Contact Center Enterprise data sources, labeled Packaged CCE or Unified CCE Historical and Packaged CCE or Unified CCE Real time in Intelligence Center's data sources tab, to use the Contact Center Enterprise stock reports. These data sources can be the same AW/HDS server or you can configure them to use two different servers. The Cisco Unified Contact Center Enterprise Solution Reference Network Design(SRND) provides detailed information about database deployment models using AW, HDS and DDS and should be consulted for sizing guidance. To be used as the Packaged CCE and Unified CCE Realtime, or Packaged CCE and Unified CCE Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 23 Deployment Models Network Design - Unified Intelligence Center Deployments over a WAN Historical data source in Unified Intelligence Center, the system must include both AW and HDS. To develop custom reports on TCD records, the data source must also include the DDS. Figure 9: Unified Intelligence Center Deployment with Unified CCE for Historical and Real-Time Reporting Network Design - Unified Intelligence Center Deployments over a WAN Unified Intelligence Center can be deployed as the reporting solution with Unified CCE deployments that scale over a WAN networks. In these deployments, Unified Intelligence Center is deployed locally with one section / data center of the scaled Unified CCE deployment and can access the local AW-HDS over the Local Area Network (LAN) as well as the remote AW-HDS which is deployed along with the remote section of the Unified CCE over the Wide Area Network (WAN). Other data sources such as Unified CVP can be deployed along with Unified CCE. Firewall considerations when deploying over WAN are applicable to the data source servers and appropriate ports as described in the Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 24 Deployment Models Cisco Unified Customer Voice Portal Deployment Firewall Integration in a Wide Area Network notes should be opened, depending on the remote database configuration. Figure 10: Network Design - Unified Intelligence Center Deployments Over a WAN Cisco Unified Customer Voice Portal Deployment Cisco Unified Customer Voice Portal is a VoiceXML-based solution that provides Interactive Voice Response (IVR) and IP switching functionality on Voice over IP (VoIP) networks. It can be deployed in a standalone mode or integrated as part of Unified Contact Center Enterprise (Unified CCE) solution. Unified CVP Reporting Server as Unified Intelligence Center Data Source The Unified CVP Reporting Server component of Unified CVP is used as the data source in a Unified Intelligence Center deployment that imports reports for the Unified CVP platform. The Unified CVP Reporting component provides the basic reporting capabilities in a Unified CVP environment. This reporting server is a Windows 2008 server that hosts an IBM Informix Dynamic Server (IDS) database management system. It contains a published schema, which customers can use to create custom reports. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 25 Deployment Models Network Design - Unified Intelligence Center Deployment with Unified CVP Network Design - Unified Intelligence Center Deployment with Unified CVP The Unified CVP Reporting Server receives reporting data from the IVR Service, the SIP Service (if used), and the Unified CVP VXML Servers. The Reporting Server depends on the Call Server to receive call records. For standalone Unified CVP VXML Server deployments, one Call Server is needed per Reporting Server. The Reporting Server must also be local to the Call Server(s) and Unified CVP VXML Server(s) that it is servicing. Deploying the Reporting Server at a remote location across the WAN is not supported by Unified CVP. The Unified CVP deployment model shown in the diagram below is a not a strict requirement for Unified Intelligence Center. Unified Intelligence Center is independent of the components connected to the data source server it uses to fetch its data. Therefore the exact Unified CVP deployment can vary depending on the customer installation and on the required number of Reporting Servers available for the Unified Intelligence Center reporting nodes to connect to. Figure 11: Unified Intelligence Center Deployed with Unified CVP Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 26 CHAPTER 4 Bandwidth and Performance Requirements • Sizing Parameters, page 27 • Measured Bandwidth, page 28 • Bandwidth Requirement, page 28 • Disk Bandwidth Requirements in Virtual Environments, page 29 Sizing Parameters The following parameters combined have an effect on the responsiveness and performance of the Unified Intelligence Center desktop. Descriptions of these items are as follows: • Realtime reports: Simultaneous realtime reports run by a single user. • Refresh rate/realtime: Note that you can change the refresh rate if you have a Premium license by editing the Report Definition. The default refresh rate was changed in Unified Intelligence Center Release 8.5(3) is 15 seconds. • #Cells per report: The number of columns that are retrieved and displayed in a report. • #Historical report: Number of historical reports run by a single user/hour. • Refresh rate/Historical: The frequency that report data are refreshed on a historical report. Note that this can be changed if you have a Premium license by editing the report definition and this value can be set per report. The default is 15 minutes. • #Rows/report: Total number of rows on a single report. • Charts/dashboard: Number of charts (pie, bar, line) in use concurrently on a single dashboard. • Gauges/dashboard: Number of gauges (speedometer) in use concurrently on a single dashboard. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 27 Bandwidth and Performance Requirements Measured Bandwidth Note You can use the to find out the approximate number Sizing Calculator of reporting servers and source databases needed for your Unified Intelligence Center implementation. However, there are factors beyond the scope of the sizing calculator that may have an impact on the performance; for example, the complexity of the report, responsiveness of the source database, and so on. Use the sizing calculator as a starting point, but note that you may have to make certain adjustments if the performance is not as per the expectations. Measured Bandwidth Unified Intelligence Center bandwidth calculations were performed on a local area network with a local AWDB database and client machine running the reports. The bandwidth figures are derived from observations on the network statistics of the Unified Intelligence Center node and the AWDB HDS box serving the report data. Load figures from the test setup are as follows: A single Unified Intelligence Center user running : • Two realtime reports with 100 rows per report, with 10 columns each. • Two historical reports with 2000 rows, with 10 columns each. • Two live data report with 100 rows and 10 columns each. Note • Do not run more than ten concurrent reports on any client machine. This is a combined limit for reports that run on the Unified Intelligence Center User Interface, Permalinks, and Dashboards on the client machine. • However, you cannot run ten concurrent reports for the 200 maximum reporting users on each node. • You have fewer reporting users on a node, they can run proportionally more reports. But, no client machine can exceed the ten report limit. Bandwidth Requirement The observed bandwidth requirements for this test setup per user are: • Unified Intelligence Center <– –> AWDB bandwidth = 1159.22 kbps • Unified Intelligence Center <– –> Browser based Reporting Client bandwidth = 3023.33 kbps The exact bandwidth requirement differs based on the sizing parameters used, such as the number of rows in each report , and the number of concurrent report executions. You can use the Cisco Unified Intelligence Center Bandwidth Calculator to calculate the bandwidth requirements for your Unified Intelligence Center implementation. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 28 Bandwidth and Performance Requirements Disk Bandwidth Requirements in Virtual Environments Disk Bandwidth Requirements in Virtual Environments When Unified Intelligence Center is run in a virtual machine on C-series servers, in addition to the CPU and memory reservations, provision the I/O subsystem for 25 KB/s, with the expectation that Unified Intelligence Center at full load consumes on average 10 KB/s of this bandwidth. Peak I/O throughput requirement reaches 25 KB/s. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 29 Bandwidth and Performance Requirements Disk Bandwidth Requirements in Virtual Environments Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 30 CHAPTER 5 Cisco Unified Intelligence Center Guidelines The following are a brief collection of considerations, which if you follow while deploying Unified Intelligence Center, provide the optimal operation of the application. • Centralized Ownership and Administration, page 31 • Dashboard Design, page 31 • Refresh Rate, page 31 • Data Source Access Across WAN, page 32 • Unified Intelligence Center Server Access Across WAN, page 32 • Report Design, page 32 • Browser Client for Reports, page 32 • Scheduled Reports, page 32 • Live Data Reports, page 32 Centralized Ownership and Administration The administration and design of Unified Intelligence Center is best left to a centralized team who are responsible for ensuring proper report and dashboard design, as well as managing ongoing system utilization. Dashboard Design Create targeted dashboards for users and eliminate elements that are not required for those users. Focus dashboard design on just what people need. Refresh Rate When possible, increase the time between the refresh (increase the refresh rate) to reduce access to the database. By default, realtime reports are set to refresh every 15 seconds, and historical reports are set to refresh every 15 minutes, but each custom report definition can be set to a unique refresh rate. Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 31 Cisco Unified Intelligence Center Guidelines Data Source Access Across WAN Data Source Access Across WAN Unified Intelligence Center nodes should not be using data sources across the WAN. For example, Unified Intelligence Center node on Side A should not access data from data source on Side B, unless explicitly provisioned, as this requires extra WAN bandwidth. Unified Intelligence Center Server Access Across WAN Bandwidth calculator does not take into account the amount of bandwidth required to support clients over the WAN. Cisco strongly recommends that Unified Intelligence Center users be local to their Unified Intelligence Center server, otherwise, the Client > Unified Intelligence Center bandwidth must be taken into account. Size the bandwidth required to support clients over the WAN according to the reporting profile being used. Report Design Use a lab or a non-production system for report development and testing prior to deployment. Import the finished reports into the production server after testing in the lab environment. Build reports with an historical summary skill group or call type data rather than with individual agent or call records to optimize database queries. There are fewer records to report on in the summarized forms, which results in improved performance. For example, whenever possible, use Agent Team reports in Unified CCE deployments instead of Agent reports, if the former can suffice. Browser Client for Reports Mozilla Firefox is the preferred client of choice for administrators in scaled deployments, due to the large amount of data that appears. Unified Intelligence Center pages render faster on the Firefox platform. Scheduled Reports Identify the reports that are run daily and shared among various users and use the scheduling function in Unified Intelligence Center to send email or update dashboards with this data. For example: if all managers in a call center require the same Daily Skill Group and Call Type Reports, schedule those reports for email delivery or to update a common dashboard. Evaluate any reports that require more than 30 seconds to render to determine if you can optimize or schedule the report for a time of lower system use, especially if they access a large amount of data. Live Data Reports Optimum user experience for Live Data reports is obtained when the number of rows in the report fits into a single page on the browser. This can be achieved by splitting larger Live Data reports into multiple reports Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 32 Cisco Unified Intelligence Center Guidelines Live Data Reports by the appropriate use of filters and view these reports in multiple tabs in the Unified Intelligence Center Report Viewer or in different windows in the dashboard.

Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 40 Citrix NetScaler Load Balancer Configuration HTTPS Load Balancing Configuration HTTPS Load Balancing Configuration Create virtual server entries, one for each port. In Unified Intelligence Center, three ports require monitoring (HTTP ports 80, 8081 and https port 8444). Each virtual server entry is the IP and port combination which receives the HTTP traffic from client (accessing Unified Intelligence Center report). Virtual servers are required to be linked with servers, to send load traffic. To check the status of the server’s monitors, they need servers assigned to each. Using the monitors, load detects the server (Unified Intelligence Center) failure and redistributes the incoming traffic to servers which are in good health to serve the requests. The relationship is Virtual Server > Service and Server > Monitor. To configure HTTPS load balancing: • Create Monitors • Create Servers • Create Services with Server association • Link each service to corresponding monitors • Create virtual servers • Link corresponding Services with virtual Servers • Create Persistency Group and add virtual Servers Cisco Unified Intelligence Center Solution Reference Network Design (SRND), Release 11.0(1) 41 Citrix NetScaler Load Balancer Configuration HTTPS Load Balancing Configuration The following figure depicts three virtual server entries and its relationship.
