The title mentioned fill metric before, but we sure can think of others too.

Suggestion:

hit/miss counters, hit counter with source type label - db or fstree
put counter with source type label
delete counter with source type label
flushed counter with source type label
actual objects count - it's look like 2 - (3 + 4), but i think it should be separate counter to not handle metric overflow cases
put, get & head, delete duration
mode (readonly, readwrite, etc)
estimated size
