How to safely purge logs on BIG-IP (disk usage high)

Hi All,

I would like to ask for the best practice to purge/clean log files on BIG-IP system.

Current situation:

- Disk usage is getting high due to log files

- Logs located in /var/log (e.g. ltm, asm, audit, etc.)

Questions:

1. What is the recommended way to purge or rotate logs safely?
2. Can we manually delete logs under /var/log ?
3. Is there any tmsh command or utility tool to manage this?
4. How to configure log rotation properly?

Thanks in advance!
