Directoryscan Option

The  SNMP option selects whether or not the subagent performs scans of the MTA&#x27;s on-disk channel message queues to count   message files, and update its information on  the oldest message files. That information corresponds to the mtaGroupLoopsDetected, mtaGroupOldestMessageStored and mtaGroupOldestMessageId MIB variables; see MIB variables served. When this option has the value 1 (or "true" in legacy configuration), then a cache of this information is maintained and updated as needed. Sites with thousands of queued messages, if not interested in these particular MIB variables, should consider setting this option&#x27;s value to 0, as performing the message queue traversal involves some overhead.

This option applies to both the Net-SNMP based SNMP subagent, and the legacy SNMP subagent for Solaris 9 and earlier.

The default value is: 1
