Due to a bug in Java version "Java HotSpot(TM) 64-Bit Server VM 1.7.0_05" JMX metrics will not be activated and reported in the Investigator.

In the IntroscopeAgent.log you will see the below errors when DEBUG tracing is enabled:

 

7/15/14 03:06:01 PM MESZ [DEBUG] [IntroscopeAgent.JMX Service] Error getting MBean info, this may be a transient failure

7/15/14 03:06:01 PM MESZ [DEBUG] [IntroscopeAgent.JMX Service] JMX data unavailable for JMX|java.lang|name=G1 Old Generation|type=GarbageCollector:LastGcInfo, this may be a transient failure

 


Workaround: Use JVM 1.6 or JVM 1.7 version higher than 1.7.0_05.
