A.3.4 Monitoring Multiple Instances of Messaging Server

Two techniques for monitoring multiple instances of Messaging Server running on the same host computer are herein discussed. The first technique, running the subagent in standalone mode, is well suited to high-availability failover (HA) configurations in which the individual instances of Messaging Server may dynamically move between host computers. The second technique, the use of SNMP v3 context names, has some limited benefit in situations where multiple instances of Messaging Server are confined to a single system and it is desirable to limit the number of IP addresses polled by SNMP monitoring software (for example, when licensing of the monitoring software has a per IP address cost component). This latter technique may also be used in HA failover settings but would require polling just as many IP addresses as the standalone mode technique.
