I hope this helps, The relevant contents of my monitor.xml file follow:

<DISCOVERED_AGENT name=".MessagingAgent.IMSERVER.MessengerService.GW MSG.SVS.MCG" address="messenger.mcg.edu" port="8330" type="TYPE_NMMA" assigned="" />
<DISCOVERED_AGENT name=".ArchiveAgent.IMSERVER.MessengerService.GWMS G.SVS.MCG" address="messenger.mcg.edu" port="8331" type="TYPE_NMAA" assigned="" />
