134 Appendix C. ProbesIn order to obtain this higher level of granularity, the BEA Domain Admin Server parameter mustbe used to differentiate between the Administration Server receiving SNMP queries and the ManagedServer undergoing the specified probe. If the host to be probed is the Administration Server, then theBEA Domain Admin Server parameter can be left blank, and both the SNMP queries and the probewill be sent to it only.If the host to be probed is a Managed Server, then the IP address of the Administration Server shouldbe provided in the BEA Domain Admin Server parameter, and the Managed Server name shouldbe included in the BEA Server Name parameter and appended to the end of the SNMP CommunityString 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 Serverhosts should be in the form of community_prefix@managed_server_name in order for theSNMP query to return results for the desired Managed Server. Finally, SNMP must be enabled on eachmonitored 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 theBEA website for more details about BEA’s community string naming conventions:http://e-docs.bea.com/wls/docs70/snmpman/snmpagent.htmlC.3.1. BEA WebLogic::Execute QueueThe BEA WebLogic::Execute Queue probe monitors the WebLogic execute queue and provides thefollowing 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).Field ValueSNMP Community String* publicSNMP Port* 161SNMP Version* 1BEA Domain Admin ServerBEA Server Name* myserverQueue Name* defaultCritical Maximum Idle Execute ThreadsWarning Maximum Idle Execute ThreadsCritical Maximum Queue LengthWarning Maximum Queue LengthCritical Maximum Request RateWarning Maximum Request RateTable C-4.
