Description

   A new, cluster-wide database of channel counters can be created
   with the COUNTERS CRDB command. The new database will have all
   counters zeroed except for the count of messages stored in each
   channel. Those counts will be determined by entries in the PMDF
   queue cache database. In addition, if an in-memory section for
   association and channel counters on this node does not already
   exist, it will be created as well.

   Once the on-disk, cluster-wide database exists, you may use
   the COUNTERS SYNCHRONIZE command to merge the information from
   the node-specific, in-memory cache of counters into the on-disk
   database.
