Description
We get the mds cache oversize health warning when mds cache usage exceeds `mds_cache_memory_limit` by `mds_health_cache_threshold` (150%).
'mds_cache_mem_rss' perf counter is used to identify the cache usage.
Currently it has a priority of 0, that is, `PRIO_DEBUGONLY`
Recommending to make it `PRIO_USEFUL` so that it can be used to alert customers about the mds cache usage without having to wait for the ceph health warning.
