Is there a way to add custom-labels or environment tags after the agent is already connected?
We have a case where several pmm agents were connected to the pmm server without adding an environment tag or custom-labels. I need these added in after the fact. Normally I would just login to a dev server and run commands until I figured out something that works, but unfortunately, we have very limited ability to connect to these servers (have to ask someone else to do it). So I want to double-check with you all before I attempt anything.
Can I just run
pmm-admin add --environment=stuff --custom-labels="foo:bar" ?
or do I have to run the full
pmm-admin add mysql user pass --environment --custom-labels
If I have to run the full second command, will it cause any issues on an already connected agent?
