Performance Monitor Instrumentation

This section explains the terminology that is associated with the Performance Monitor instrumentation. Instrumentation refers to the modifications that are made to internal PeopleSoft programming code that enables the system to report performance data to a monitor. Selected areas of PeopleTools runtime source code are instrumented.

When the system runs instrumented code, it generates time-stamped performance metrics that are relevant to that section of code. Agents running on the monitored system send the performance data to the Performance Monitor.

Instrumentation generates performance measurement units (PMUs) and events.
