144 Appendix C. Probes
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. Thiscauses the SNMPqueries to be sent tothe Administration Server host, asis 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 community_prefix@managed_server_name in order for the
SNMP query toreturn results for the desired Managed Server. Finally, SNMP mustbe enabled oneach
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:

C.3.1. BEA WebLogic::Execute Queue
The BEA WebLogic::Execute Queue probe monitors the WebLogic execute queue and provides the
following metrics:
• Idle Execute Threads — The number of execution threads in an idle state.
• Queue Length — The number of requests in the queue.
• Request Rate — The number of requests per second.
This probe’s transport protocol is User Datagram Protocol (UDP).
