We are seeing high CPU load on a Docker install of PMM latest and the PMM web UI is somewhat sluggish.
I have searched the forum and METRICS_MONITOR is mentioned on cpu load. Right now we don’t have METRICS_MONITOR set since memory usage seems to be ok. PMM client network check looks ok.
Currently monitoring 38 RDS nodes, but planning to add a further 60 nodes. So scaling is a concern and slowness on the PMM web interface.
We have the pmm server and client installed on the same VM. This is the first time we have tried this setup, so that may be an issue.
Running on a VM that is dedicated to pmm only. 6 CPU at this time and 15G ram.
mainly monitoring RDS instances, so using Performance schema and innodb_monitor_enable=all
have pmm client v1.9.1 and server v1.8.1. Note we have the server and client running on the same VM.
prometheus is using the most CPU
PMM server container settings
sudo docker run -d
Have attached files showing
- tail prometheus log
- top output
- sar output
- pmm client network check
