JMX Mini Probe - Custom Mbean monitoring

Votes:

2

Hi,

I have installed the JMX Mini Probe and I am now trying to add a custom MBean sensor. I managed to monitor simple Mbeans like the following:

Mbean: java.lang:type=Threading Attribute Object Name: ThreadCount

But now I want to monitor MBeans which have more layers, like the following:

java.lang:type=MemoryPool,name="PS Perm Gen" -A Usage -K used -I Usage -J used

The Attribute is 'Usage', but what is the syntax for the Mbean and name in this case ?

A second question, a specific attribute can have multiple channels (like Thanks Grtz, Tom

java jmx mini-probe

In the meantime, I figured out that the problem was not with the Mbean name java.lang:type=MemoryPool,name="PS Perm Gen" which works correctly, but with the fact that the attribute was not a normal count value.

Instead, tomcat uses multiple keys under the attribut. In JMX, you have to use the -K parameter to specify the key you want to read under the selected attribute.

As far as I can see, this -K parameter is not implemented in the current release of the mini probe.

Full JMX command line to get back what I want:

java.lang:type=MemoryPool,name="PS Perm Gen" -A Usage -K used -I Usage -J used

I think I'll have to wait for a new version which implements this functionality.

That is not supported at this time, you are correct. It has been added to the TODO list, though.
