Alarm and System Message Overview
The Cisco ACNS Alarms and Error Messages Guide lists and describes the error messages for the
Application and Content Networking System (ACNS). The system software sends these error messages
to the console (and, optionally, to a logging server on another system) during operation. Not all error
messages indicate problems with your system. Some messages are purely informational, while others
may help diagnose problems with communications lines, internal hardware, or the system software.

System Message Structure
System error messages are structured as follows:
FACILITY-SEVERITY-MNEMONIC: Message-text
FACILITY code
The facility code consists of two or more uppercase letters that indicate the facility to which the message
refers. A facility can be a hardware device, a protocol, or a module of the system software.
In the ACNS context, the facility code is CE and refers to Content Engine.
ACNS error messages also indicate where the system condition occurred. These messages are structured
as follows:
FACILITY-SOURCE-SEVERITY-MNEMONIC: Message-text
Source indicates the location of the condition. Examples of source are ACQ, which indicates that the
condition occurred in the Acquisition component, or SYSMON, which indicates that the condition
occurred in the System Monitor component. Table 1-1 lists the source codes in ACNS.

Severity Level
The severity level is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower
the number, the more serious the situation. Table 1-2 lists the message severity levels.

Message Severity Level
Severity Level
Description
0 - emergency
System is unusable
1 - alert
Immediate action is required
2 - critical
Critical condition
3 - error
Error condition
4 - warning
Warning condition
5 - notification
Normal but significant condition
6 - informational
Informational message only
7 - debugging
Message that appears during debugging only
Mnemonic code
The mnemonic code uniquely identifies the error message.
Message-text
Message-text is a text string that describes the condition. The text string sometimes contains detailed
information about the event, including terminal port numbers, network addresses, or addresses that
correspond to locations in the system memory address space. Because variable fields change from
message to message, they are represented here by short strings enclosed in square brackets ([ ]). The
variables give you more information about the system condition. A decimal number, for example, is
represented as [dec]. Table 1-3 lists a sample of the variable fields that you will find in this publication.

System Message Example
The following is an example of a system error message:
CE-ACQ-2-100009: Failed to read Channel=[chars], Channel table may have been
dropped accidentally. Restarting acquirer to wait for its creation.
•
CE is the facility code.
•
ACQ is the source code.
•
2 is the severity level.
•
100009 is the mnemonic code.
•
Failed to read Channel=[chars], Channel table may have been dropped accidentally. Restarting
acquirer to wait for its creation is the message text.
Searching for System Messages
If you search for the explanation and recommended action of a message that contains a SOURCE,
remove the SOURCE from the text first, and then search for the message in the documentation.
For example, instead of searching the documentation for the message CE-ACQ-2-100009, remove the
source identifier and search for the message CE-2-100009.
When searching for a message in the Error Message Decoder (EMD) also, you must remove the source
identifier.

Alarm and System Message Overview
Alarm Structure
Alarm Structure
Cisco ACNS alarms are structured as follows:
MESSAGE_TYPE-SEVERITY-SOURCE-MNEMONIC: Alarm-text
MESSAGE_TYPE
A three letter code indicating the message is an alarm.
SEVERITY
An alarm can have the severity levels critical, major, or minor.
A critical alarm indicates that a critical problem exists somewhere in the network. Critical alarms cause
failover. Critical alarms should be cleared immediately.
A major alarm indicates that a serious problem exists that is disrupting service. Major alarms differ from
critical alarms in that they do not cause failovers. Major alarms should also be cleared immediately.
Minor alarms should be noted and cleared as soon as possible.
SOURCE
The component from where the alarm originated.
MNEMONIC
A unique code for identifying the alarm.
ALARM TEXT
A brief description of the alarm.
Sample Alarm
Given here is an example of an alarm:
/alm/min/acquirer/zerobandwidth: specified content acquisition bandwidth is 0
•
alm is the message type.
•
min is the severity level.
•
acquirer is the source code.
•
zerobandwidth is the mnemonic.
•
specified content acquisition bandwidth is 0 is the alarm text.
