[grayloglearn]

Hi Team,
I just want check with you is there any relation to between kworker and ksoftirqd to any nagios services(nagios,mariadb,npcd).
We have been facing issue with kworker and ksoftirqd with high CPU utilization. As we know that both are related to kernal process.

Any nagios services is depending on any kernal kworker and ksoftirqd process/services. could you please confirm that.
any suggestion could you please provide to reduce the utilization.

Hello @grayloglearn,

It's quite normal to see a number of kworker processes when running Nagios, but if your system is under sustained CPU loads or is crashing this could be a symptom of another issue.

Please send us your system profile so we can review the logs. Thanks.

To send us your system profile.

Take a look at the guide below for increasing performance in Nagios XI. What is your check load ( check load = total number of hosts + services) on this sever?
