We recently changed the hostname of one of the servers we are monitoring using percona monitoring for MySQL.

After the hostname change, I noticed that on the monitor dashboard, the server was still showing up with its old name, and receiving data as such.

So I did a pmm-admin uninstall, then pmm-admin config specifying the new hostname and finally pmm-admin add mysql

After this, the new server showed up on the dashboard but the old one was not removed.

Is there a way for me to force remove the old server?

Thanks.
