Class PerformanceMonitor

java.lang.Object
  java.lang.Thread
      com.hazelcast.util.PerformanceMonitor

All Implemented Interfaces:

Runnable

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.
