Sites running the DEC-supplied DIGITAL Commander monitoring package (also known as Enterprise Mail Monitor, EMM, or PolyCenter MAILbus Monitor (PMM)), can monitor PMDF using the PMM scanning module supplied with PMDF. The scanning module sends to PMM software version, time zone, queue, job, and monitor records. The contents of each of these records is described in Section 32.5.3 . Note that PMDF channel counters are sent in the monitor records.
