WebSphere brand IBM WebSphere Presence Server, Version 7.0

Performance metrics

WebSphere Performance Monitoring Infrastructure (PMI) indicators provide a comprehensive set of data to help explain the behavior of applications and the resources they consume.

As an alternative to using the Integrated Solutions Console, you can enable and disable PMI using the PMI tag in the Presence Server configuration file, SystemConfiguration.xml. See the topic Configuring performance for details.

The following tables list the metrics (indicators and counters) that are supported for the Presence Server product.

Rate counters

The following tables list PMI-based indicators used by Presence Server. Use the PMI tag in the SystemConfiguration.xml file to activate the indicators and specify how you want to monitor their output.

The following PMI-based indicators track the rates at which various events occur.
