jmx-repl

A JMX client with a file system style. You use ls to check all the mbeans, use cd to go down one level, and use cat to check the attribute value of a mbean's attribute.

In jmx-repl the following jmx bean:

java.lang:type=MemoryPool,name=CMS Old Gen

translates to the following path:

/java.lang/MemoryPool/CMS Old Gen

i.e. in jmx-repl, java.lang, MemoryPool, CMS Old Gen are all directories, the attributes of this bean are "file" in jmx-repl.
