Cleanup not working with 2.99.x

[lifeofguenter]

When removing plugins from nodes or removing nodes from munin.conf, no deletion takes place, which means:

• we have empty plugin graphs
• nodes are not removed

My suggestion would be:

1. use munin.conf as source of truth, delete entries from db if not found in munin.conf (during startup)
2. during node config, update db and remove entries

I specifically didn't want to delete plugins, as it would be data destruction.

That said, the UI could be tweaked to filter out no-recently-updated plugin. then providing the option to still show them as opt-in.

True, but then also you can end up with a bunch of empty graphs.

Maybe compromise of making this UI only setting as you mentioned.

This seems to be the case with 2.0.x as well. So how do you correctly remove a decommissioned node and its outdated data?
I seem to remember this wasn't the case in earlier versions, they just disappeared from the list when simply removed from munin.conf.
