Before you begin
You can use the Performance Monitoring Infrastructure (PMI) interfaces to develop your own applications to collect and display performance information.There are three such interfaces - a Java Machine Extension (JMX)-based interface, a PMI client interface, and a servlet interface. All three interfaces return the same underlying data. The JMX interface is accessible through the AdminClient tool as described in Developing your own monitoring application with the Java Management Extension interface. The PMI client interface is a Java interface that works with Version 3.5.5 and above. The servlet interface is perhaps the simplest, requiring minimal programming, as the output is XML.
