Nagios process high CPU usage

[amit.ahuja]

Hi, we are having some problem with the nagios process. We are experiencing server slowness now, and we figured that the cpu usage of nagios process was increased to 100 every 5 to 10 mins. The odd thing is that 2 or 3 nagios processes were running and all of them have like 99 percent cpu usage. Please see the attach screenshot. Thanks in advance for any suggestion and help.

A better way to check for multiple nagios processes is to run ps - aef | grep nagios.cfg

# Look for multiple parent (PPID) processes. The Nagios process forks itself to run checks therefore subprocesses are normal
# The nagios user should probably be the only owner of the nagios process
# 'service nagios restart' will still leave the extra Nagios processes running, so this is not an option

If there are multiple Nagios processes running, this can cause problems. To resolve, run these commands

Code: Select all

service nagios stop
killall -9 nagios
service nagios start

Beyond that, how many services are configured and what are the specs of the XI machine, resource - wise?

Thanks for the reply, we removed some services in Nagios, and this issue got resolved.

Is it alright if we lock this thread?
