[collectd] Plugin:GenericJMX -- Best Practices to monitor 2 JVMs on same host

[Poil]

Hi,

I collect Karaf and cassandra on a same host
I use somethink like this

   <Plugin  "GenericJMX">
     <MBean  "cassandra/classes">
       ObjectName "java.lang:type=ClassLoading"
       InstancePrefix "cassandra_java"
       <Value>
         Type "gauge"
         InstancePrefix "loaded_classes"
         #InstanceFrom ""
         Table false
         Attribute "LoadedClassCount"
       </Value>
     </MBean>

     <MBean  "karaf/classes">
       ObjectName "java.lang:type=ClassLoading"
       InstancePrefix "karaf_java"
       #InstanceFrom ""
  
       <Value>
         Type "gauge"
         InstancePrefix "loaded_classes"
         #InstanceFrom ""
         Table false
         Attribute "LoadedClassCount"
       </Value>
     </MBean>

<Connection>
Collect "karaf/classes"
  Collect "cassbandra/classes"
</Connection>
