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?

Hi @Jeff_K at this time there is no way to change an environment tag or label. What we recommend is that you **remove** then **add back** the service, and include the new tags/labels you want to include (or remove, or modify).

pmm-admin remove mysql db1-mysql

pmm-admin add mysql … --environment=“production” --replset=“App1” …

Hi,

but what if I want to set the environment tag on a node which only does Linux OS metrics collection?
