In this chapter, we have introduced some of the most popular tools available in the market for monitoring the JVM, the application server, its application deployed, and the operating system. These are the essential points covered:
VisualVM is a monitoring tool developed by Sun, which can be used to analyze JVM heap data, track down memory leaks, monitor the garbage collector, and perform memory and CPU profiling.
The Eclipse TPTP Platform covers the entire performance lifecycle so it can be used also as an all-in-one solution for your projects. In this chapter, we have learnt how to use it to profile and test your server applications.
JMeter is a well-known application, which can be used to set up benchmarks of your web applications but can be equipped for a variety of tests as well.
Each operating system has built-in tools, which can monitor your hardware resources.
