The contents of the cluster-wide channel counter database may be
    displayed with the COUNTERS SHOW command. By default, before the
    counters are displayed, an implicit COUNTERS SYNCHRONIZE command
    will be executed, to attempt to synchronize each node-specific
    cache with the main cluster-wide database. Specify /NOSYNCHRONIZE
    to merely display the current contents of the database without
    first synchronizing the node-specific caches.

    Note that SYSLCK privilege is required to perform the
    synchronization step.

    Note that the output of PMDF QM's COUNTERS SHOW command is
    currently not as detailed as the output of the DCL level PMDF
    COUNTERS/SHOW command.
