C.3. BEA WebLogic 6.x and higher

The probes in this section (with the exception of JDBC Connection Pool) can be configured to monitor the properties of any BEA WebLogic 6.x and higher server (Administration or Managed) running on a given host, even in a clustered environment. Monitoring of a cluster is achieved by sending all SNMP queries to the Administration Server of the domain and then querying its Managed Servers for individual data.

In order to obtain this higher level of granularity, the BEA Domain Admin Server parameter must be used to differentiate between the Administration Server receiving SNMP queries and the Managed Server undergoing the specified probe. If the host to be probed is the Administration Server, then the BEA Domain Admin Server parameter can be left blank, and both the SNMP queries and the probe will be sent to it only.

If the host to be probed is a Managed Server, then the IP address of the Administration Server should be provided in the BEA Domain Admin Server parameter, and the Managed Server name should be included in the BEA Server Name parameter and appended to the end of the SNMP Community String field. This causes the SNMP queries to be sent to the Administration Server host, as is required, but redirects the specific probe to the Managed Server host.

It should also be noted that the community string needed for probes run against Managed Server hosts should be in the form of [email protected]_server_name in order for the SNMP query to return results for the desired Managed Server. Finally, SNMP must be enabled on each monitored system. SNMP support can be enabled and configured through the WebLogic Console.

Please see the documentation that came with your BEA server or information on the BEA website for more details about BEA's community string naming conventions: http://e-docs.bea.com/wls/docs70/snmpman/snmpagent.html
