Research direction
Start by investigating CouchDB 3.5.0 metric registration and logging for mem3, shard_cache, and hit on a fresh single-node installation. Reproduce the daily unknown-metric errors and compare the behavior with the reporter's other CouchDB servers. Done means the valid metric no longer produces millions of erroneous unknown-metric errors.
Written by the indexing model from the issue text.
Description
Version
3.5.0
Describe the problem you're encountering
Every day one of my CouchDB servers registers millions of "unknown metric" errors.
Example: "unknown metric: [mem3,shard_cache,hit]"
We do not have any 3rd party monitoring tools.
This is a fresh install of CouchDB 3.5.0 and a single node.
Expected Behaviour
I expect for their not to be millions of these errors as this does not happen on our other CouchDB servers even after a fresh install.
