Nagios Support Forum

Hi,
I noticed that at least once in a week my Nagios XI stops functioning and the only way to resolve it is to kill the Nagios workers.

In a normal day work, there are 12 workers. However, during the week they are growing, everytime there are 12 new workers created with a new ID.
what is the reason and how can I solve it?

Killing the workers isn't the right way, they are likely needed.

Can you describe in more detail by this: my Nagios XI stops functioning?

A profile generated in one of this suboptimal states may be useful as well if it is possible.

Please include the zip file in your response. You can PM myself or other support personnel it as well.

Just checking in since we have not heard from you in a while. Did @avandemore's post clear things up or has the issue otherwise been resolved?

Hi,

Hi,
Send you a PM.

Looking into your profile, the logs date back to June 20th? Could you send us an updated profile?

From your top command, you are experiencing 100% CPU usage from mysqld.

How many hosts/services do you have?

Did you offload your database?

The best thing would be to send us an updated profile, so we can see how things are looking now.

sent you the profile file

How many hosts/services do you have?

Is this an offloaded DB?

UPDATE: Profile received!

Put in teamshare.

We have about 1700 hosts and 31k service checks.
Offloading the DB caused more issues.
