Monitoring the MTA

For monitoring the MTA, usually the best place to start is with the MTA&#x27;s optional logging of message  traffic; from this basic information,  sites may gather statistics such as how many messages are passing  through the MTA, and answering other questions on message traffic.

The command line utility   may be used to scan what messages are present in the MTA queue area.

The MTA also has facilities to collect and monitor channel counters  based upon RFC 1566, the Mail Monitoring MIB. Note that counters are intended for providing real-time "snap-shots" of MTA  behavior, rather than for gathering the sort of statistics instead  available from the log files. For a description of the MTA counters, see the discussion of MTA counters.

The MTA provides utilities to display the counters directly; see the   and     utilities, described in  MTA command line utilities.
