Monitoring of Java Virtual Machines with JMX: Why am I unable to get attributes coming from other MBEANS?

Hi All, I use the app Monitoring of Java Virtual Machines with JMX and it works really well to get some attributes from java.lang. However, I tried to retrieve some other values coming from other MBEANS, but I don't see anything into Splunk (for the "org.apache.camel" domain). At least, I expect to see errors into the internal index saying the attributes does not exist! Below are the lines I added into the config.xml: As you can see in the following screenshot this attribute exists! Any idea ? Thanks a lot ! Romain.
