VisualVM is a free command line JDK integrate multiple visualization tool performance analysis tools, and has now been included JDK, named: jvisualvm. If you are a Javaer, strongly I suggest that you be able to use it because it can not only generate and analyze massive amounts of data, tracking down memory leaks, monitoring garbage collector, memory and CPU to perform the analysis, but it also supports browsing and operations on MBeans . 
Currently VisualVM has made visualvm.java.net moved to visualvm.github.io , so if you use JDK under jvisualvm, when you install the plug-in will fail, you can Tools -> Plugins -> Settings add the latest plug-in centers such as: https://visualvm.github.io/uc/release139/updates.xml.gz 
The latest versions of plug-in center can see here: https://visualvm.github.io/pluginscenters.html 
Good Luck!
