      The pingMs and lastHearbeatMessage fields in the members array of the replSetGetStatus command occur sporadically. The fields appear to be alternately present for a couple of seconds and missing for a couple of seconds.

      This creates frequent schema changes that reduce the compression efficiency of FTDC storage by a factor of 5-10x.

      Observed behavior in 3.0 is that pingMs is always present (and lastHearbeatMessage seems to be new for 3.1).
