CiscoWorks Server Syslog file is growing

Question

Hi ,
I have a Ciscoworks server in which syslog.log file are continueously growing everyday in size.When i checked the syslog file i have observed that most of the logs related to DOT1X-5-SUCCESS or AUTHMGR.Because of this syslog file size is increasing like anything.Is there any way where i can filter this log file and drop in ciscoworks server itself. By achieving this i can reduce the size of the syslog file and also block non required logs.
If there is any way then please let me know how do i achieve.
Thanks in advance.
Thanks & Regds,
Lalit

The best way to control the syslog.log is to control the device sending syslog messages. If that is a specific one which is sending a lot of messages configure the device not to send any syslog to control the size.
For details on how LMS Syslog works, please check my document :

If this is not viable, the best way to control the syslog.log or any log file is to configure Logrot Utility within Ciscoworks.
Log files rotation helps you manage the log files more efficiently. See Maintaining Log Files for an overview of maintaining the log files in CiscoWorks Server.
Logrot is a log rotation program that enables you to control the log files size growth. It helps you to:
            > Rotate log files while CiscoWorks is running.
            > Optionally archive and compress rotated logs.
            > Rotate log files only when they have reached a particular size.
Logrot helps you easily add new files. You can configure Logrot either from the UI or from the CLI.
