Class PerformanceMonitor

  extended by java.lang.Thread
      extended by com.hazelcast.util.PerformanceMonitor
All Implemented Interfaces:

public class PerformanceMonitor
extends Thread

The PerformanceMonitor is responsible for logging all kinds of performance related information. Currently it only shows the read/write events per selector and the operations executed per operation-thread, but new kinds of behavior will be added.

This tool is currently mostly used internally or unless you are an expert. In the future it will become more useful for regular developers. It is also likely that most of the metrics we collect will be exposed through JMX at some point in time.
