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
community_prefix@managed_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:

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).
