Hi. The pmm-agent loads the processor heavily. Can you tell me which settings I need to check to solve this problem? ![pmm-agent](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/3X/9/8/98cf7372d5f7e4b98c9789c7930b97d026c383ba.png) ![pmm-agent-cpu](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/3X/8/c/8c8ceb50281ce245da3dac872a6f2be733979bab.png) ---

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: ![Screenshot 2024-09-27 at 7.34.31 AM](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/3X/d/8/d8850b10dd6e581c9ae3fca0b4ca008a42bed09d.png) Have you tried restarting the agent on this db server? ---
