The mds, mds_server etc refer to internal subsystems within the
ceph-mds process (their naming is arcane).
The abbreviated names for performance counters are the "nick" item in
the output of "ceph daemon <xyz> perf schema" -- for sufficiently
recent code you should see a description field there too.
