Installation guide

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 Dom ain 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 Dom ain 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 Comm unity
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 comm unity_prefix@ managed_server_nam e 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.
See the documentation that came with your BEA server or information about the BEA website for more
details about BEA's community string naming conventions.
A.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 - T he number of requests in the queue.
Request Rate - T he number of requests per second.
This probe's transport protocol is User Datagram Protocol (UDP).
