I’ve setup PMM for a XtraDB Cluster. This has been running fine.
Now we upgraded a couple of servers and the new servers are reporting nicely in the PMM interface. However in the targets of Prometheus I still got 1 server that has been removed (and already removed physically) which is being seen as down. I want to remove this server from being polled, but I have no idea where to change this in the PMM docker. It most likely somewhere registered in a yaml file, but I can’t seem to find where.
Bare in mind I don’t have access to the old server anymore, so I can’t unregister it with the pmm-admin client.
How would the best way to remove a server that doesn’t exist anymore?
