We are using pmm-server (1.x) for two years in one docker container with this specs:
8GB of RAM
23 clients configured ( almost 200 databases)
All the customers have configured pmm-agent with mysql.
All works perfect.
But we upgraded our container to pmm-server 2.11. After all the configuration, our docker container dies in 3 minutes.
After some research whe see with the same scenario can only configure 6 clients (pmm-admin). If we configure more than these, our containers eats all memory and docker kill the container (OOM)
Is there any option with version 2 i missing?
We are planning to rollback to the previus version of pmm. If we can take the same configuration with version 2
Attach our docker stats with 6 pmm-clients configured:
