Hi,
How do I change time of daily logrotate? ( hour and minute )
I know when set daily configure for logrotate , this uses cron.daily setting. but I want to distinguish between logrotates ( for example : apache logrotate, daliy : 04:00AM , and syslog daily 06:00 AM )
thanks

i'd really suggest you don't bother, what are you goign to benefit from changing something that is working just fine on millions and millions of servers worldwide?

If you really have to, you'd need to split the logrotate configs out to separate files and call each on directly from a new cron entry, referencing a different config, e.g. logrotate-messages.conf. I really wouldn't do this though.

I know this fact about logrotate, but server status is critical at this time!
When logrotate script runs , load average goes up and services would be disrupted!
I need to resolve this problem , just at this time not forever!
thanks

I agree it doesn't make sense but
should you want to do it anyway then
and use the output of
as an example of what to tweak and add to /etc/crontab. After that you're responsible for the extra maintenance burden so document it and don't complain if something breaks.

Then find out the cause or send logs to a central syslog server for processing there?

cause of this problem is constraint of hardware on this server( RAM & CPU). I decide to migrate to another server, but I need to resolve this problem at this time,
thanks

Unless you use prerotate / postrotate processing in the logrotate script all it does is delete the oldest log, create a new file and possibly compress the rotated log. So find out what exactly is hogging resources. On newer machines you could check if you could wedge the process into some low-priority cgroup, on older machines you could try execute that logrotate instance with ionice + nice (though child processes like gzip don't inherit any ionicing IIRC) or if logs are way large you could opt for processing them multiple times a day instead. Using a separate syslog server alleviates all of that.
