I would recommend logrot for LMS 2.5
It will rotate the log files when they reach a certain size and you can configure it to
run daily. Logrot is a log rotation program that can:
? Rotate log when CiscoWorks is running.
? Optionally archive and compress rotated logs.
? Rotate log only when it has reached a particular size.
Here are details and instructions:
