Java – list of JMX objects and attributes?

• Java

I try to implement a Nagios plug-in, which requires me to clearly know the objects and properties I want to monitor The thing is, I can't find a list of standard system JMX objects and properties anywhere Can anyone point in the right direction? I need to monitor the memory pool, heap size, etc

Solution

You can use mbeanserver at any time queryNames(null,null); Get all MBeans registered in an mbeanserver (where mbeanserver is the mbeanserver connection you get locally or remotely)

However, before implementing your own Nagios plug-in, why not use an existing plug-in? For example Jmx4perl check_ Jmx4perl comes with tools for browsing JMX namespaces (such as jmx4perl < URL > list, which lists all JMX MBeans and their properties and operations, or j4psh JMX shell based JMX shell with context sensitive command line completion)
