Hi. The pmm-agent loads the processor heavily. Can you tell me which settings I need to check to solve this problem?
Hi @den1a, any reason to run that much pmm-agents? I suppose they are conflicting with each other and that’s why generating load. Please kill all of them except 1
@den1a Are these two screenshots from your PMM Server? If so, then this is typical when you have lots of “Remote MySQL” servers to monitor. Each ‘remote’ monitor will launch its own agent on the PMM server. This is why we recommend a dedicated server for PMM. This is also why we highly recommend that you install the PMM Client Agent on each MySQL server instead of using the remote option.
PMM Server launch agent(mysqld_exporter, not pmm-agent) per service on the PMM Server, but it doesn’t answer why there is that much pmm-agents running.
Thank you for the answer. The pmm client is installed on a server with a single site. And only 1 mysql. The persona server is located elsewhere
Thank you for the answer. I understand that the pmm-client controls the number of processes itself
Typical PMM agent running on a dedicated mysql host:
Have you tried restarting the agent on this db server?
The pmm agent behaves calmly, but every 10 minutes it starts transferring the mysql log to another server and creates a load on the processor. The graph in the first post shows hills every 10 minutes
Hmm. That does not sound normal. How big is your slow query log file? What is long_query_time set on your server?
