JMX vs VisualVM?

Question

I read couple of links about JMX and VisualVM, but still have a couple of questions around them.

As per my understanding, JMX & VisualVM are 2 different JVM monitoring tools. In-addition, JMX has APIs, which a java application could incorporate and allow the monitoring tools to better monitor the application.

Could someone clarify if this understanding is correct or flawed ? If flawed, could you please point to any articles explaining this difference/comparison better ?

Also, when do i go for using JMX or VisualVM to monitor my java based web application hosted on a Tomcat 6.1 server ?

Answer 1

That's not correct. JConsole & Java VisualVM are 2 different JVM monitoring tools. Java Management Extensions (JMX) is a Java technology that supplies tools for managing and monitoring applications, like JConsole or Java VisualVM
