Distributed Polling and MYSQL 100% CPU

Hello everyone!

I’m having problems with my LibreNMS server and hope you can give me a tip. Since the server was running at 100% CPU utilization, I integrated a second poller server. However, my main server is still running at 100% capacity. With the top command I can see that it is mysql which is eating so much.

I suspect that it could be a configuration error with polling, but I don’t know how to configure this correctly.
Therefore the following question:
The configured networks in the config.php, do the networks have to be specified on both servers?
On the main server I have the line $config[‘service_poller_workers’] = 18; added, however this did not reduce the load.

Any tips on what I’m doing wrong or what I could improve?

Best regards, VHS
