A Groovy Adapter for JMX

branch: master

Started implementation of HEAD requests to reduce traffic on class

change verifiers (e.g. JBoss deployers) and to provide a low traffic
ping point to allow remotable MBeanServer to verify the RCL is still
available.

GroovyMX - A Helios Project

GroovyMX (or just gmx) is a Groovy wrapper for JMX Clients. Taking a page from Groovy's SQL support, the idea is to reduce the amount of code to write something useful against a JMX MBeanServer.

Here's a quick example. The following script connects to a remote MBeanServer and prints the committed number of bytes in each Memory Pool.

import org.helios.gmx.*;
gmx = Gmx.remote("service:jmx:rmi://testserver1:8002/jndi/rmi://testserver1:8003/jmxrmi");
gmx.mbeans("java.lang:type=MemoryPool,name=*", {
    println "${it.objectName}:\t${it.Usage.committed}";
});

The output of the script is:

java.lang:type=MemoryPool,name=PS Eden Space:  402653184
java.lang:type=MemoryPool,name=PS Survivor Space:   16777216
java.lang:type=MemoryPool,name=Code Cache:  3407872
java.lang:type=MemoryPool,name=PS Perm Gen: 84738048
java.lang:type=MemoryPool,name=PS Old Gen:  268435456
