Software
All the Operating Systems that we use now-a-days, either Windows or an Open Source platform
like Linux, comprise of various sets of programs and events that keeps running in the background to
carry out the tasks to maintain efficient and reliable use of system resources. These events may
happen in system software, for example the init process, or user applications such as Apache, FTP
and others.
Now the question that arises in everyone's mind is - how to keep an eye on working state of the
system and different applications that are running in the background? One of the general solutions
is that the system administrator himself keeps a review on the Log-files on a daily basis from the
Production Environment.
But is this really a productive and easy factor to check each Log file on a daily basis which involves
reviewing each log file from several system areas and applications. Still it is possible but making a
user available at daily basis is not always a possible task. Here come the Log software management
tools into action. They help to monitor, review, analyse and even generate reports from different log
files as configured by a System Administrator.
