Statistics
The following table describes the default statistics supported by enabler for WebSphere Application Server. The enabler for WebSphere Application Server uses PerfServletApp to collect various performance metrics. This performance servlet (provided with IBM WebSphere as an installable application) provides a way to use an HTTP request to query the performance metrics for an entire WebSphere Application Server administrative domain.
The performance servlet provides the performance data output as an XML document. The enabler for WebSphere Application Server parses this XML document using XPath expressions defined in the enabler’s description file as supported statistics. You can select and track these statistics from the Component Wizard. Tracked statistics are available for report output. You can also create Policy rules based on any tracked statistic.
