Metric Beat and Jolokia Module

Elastic Stack Beats
1

Hi There,

I was trying out the new Jolokia module in Metric beat 5.4.

The configuration is given at the end.
The values are coming for the attributes that don't have space. For others say related to MemoryPool (PS Eden Space etc) exception is coming.

Thanks for your help!.

The exception message is:

6 errors: No key found for metric: 'java.lang:name=PS Eden Space,type=MemoryPool_Usage', skipping...; No key found for metric: 'java.lang:name=PS Eden Space,type=MemoryPool_PeakUsage', skipping...; No key found for metric: 'java.lang:name=PS Old Gen,type=MemoryPool_Usage', skipping...; No key found for metric: 'java.lang:name=PS Old Gen,type=MemoryPool_PeakUsage', skipping...; No key found for metric: 'java.lang:name=PS Survivor Space,type=MemoryPool_Usage', skipping...; No key found for metric: 'java.lang:name=PS Survivor Space,type=MemoryPool_PeakUsage', skipping...

The configuration snippet.
