I am working on a pretty large distributed Nagios core deployment and have a
question regarding resources.
It appears that almost every morning @ about 7:20 am, my cpu usage goes from
about 4% to about 25-40% . It will do this for a few hours and then go back to
4%.
It appears to me that the issue is with wwwrun running status.cgi. I was
wondering what would be going on during the morning at about the same time
every day as opposed to 24hrs / day. I was looking for some kind of
maintenance it could be doing or something but am not finding anything.
I know there are no consoles open, 99.5 % of the checks the core server is
processing are remote checks.
I know my environment will require multiple core servers ( 700 remote sites,
15 clients / site , 20 +/- checks per client ) but have been working all along
to tune the servers for the best efficiency.
Are there any tuning parameters for status.cgi??
Thanks,
Steve
