the log files seem getting bigger, is it possible to shrink the log files? or delete/remove older than specific date

Depending on your version of XI these should rotate automatically, but there isn't anything in them except debug information so you can safely do the following
Code: Select all
cat /dev/null > /usr/local/nagiosxi/var/event_handler.log
cat /dev/null > /usr/local/nagiosxi/var/eventman.log
cat /dev/null > /usr/local/nagiosxi/var/sysstat.log

It's supposed to be 5M

do you mean every 5 minutes the newly log data will overwrite old log data?
can we edit/change the rotate time interval?

Sorry, every 5MB (which in your case clearly isn't happening)

Yes, XI uses the linux log rotation and the config can be found here
It is worth pointing out there were some bugs in this and if you are not on the latest version of XI (5.6.7) you could be experiencing that.

if rotate every 5MB automatically, why log files oversize in my case?
