Automatic monitoring of WebSphere Application Server Service Integration Bus queue depth

At the time of writing this technote, there is no direct way to monitor a SIB queue depth using the WebSphere Performance Monitoring Infrastructure (PMI).

In order to retrieve the depth of a SIB queue using the WebSphere PMI, you will need to select the following two counters:

AvailableMessageCount and UnavailableMessageCount

Here is how: From the WebSphere Application Server Admin Console, go to the Performance Monitoring Infrastructure (PMI) panel of the application server where the messaging engine is hosted:

Application servers > your_app_server_name > Performance Monitoring Infrastructure (PMI)

You will be on the Configuration tab by default. You can choose to switch to the Runtime tab if you wish this monitoring to start without restarting the application server.

Once on the PMI panel, click on the link "Custom", the label of the last radio button. This should take you to the Custom monitoring level panel. From the left-hand navigation tree, select:
- SIB Service

- SIB Messaging Engines
- *
- Destinations
- Queues

Select both counters: AvailableMessageCount and UnavailableMessageCount and click the Enable button located at the top. Your setting should be saved at this point.
