Maintenance activities - Kiwi Syslog

What periodic maintenance activities are recommended/must be done for the Kiwi Syslog server?

I get that log archiving / removal is done on a scheduled basis. But what else should be done regularly for the syslog to function smoothly?

For an offline server (no internet connection) is there a reminder or message somewhere on the system that a license renewal is upcoming?

Thanks,
