So far I have backported the changes as they exist in elasticity and tried to get the test working. Right now I can see the metric for the compactor and scan server in the test but am not seeing it for the tserver yet (no metric at all) and am not sure why.

but am not seeing it for the tserver yet (no metric at all) and am not sure why.

Looked into this a bit and it seems like micrometer only reports the metric after it changes and since the tserver never became idle, the value for this metric was never emitted.

removing the WIP label as I think this is ready for review now. The only thing I need to fix is the CompactorTest which is failing in the builds. I am not sure whats going on there, maybe something wrong with the mocking in that test now.

Looks good. Just a minor comment regarding the property description.
