Wed, 07 Aug 2013 10:45:34 -0700 

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>

Hi.

I wonder how I can get same values for more than one JVMs?
I have MBeans for heap/nonheap memory values and I want to collect this data from 2JVMs. But prefix for rrd's I can setonly in MBeans block, but not in Connection block. I can setup two or more Connection block, but I will get an error "update failed"-blah-blah-blah since it tries to write the same rrd's. I see the only way to set MBean blocks with different InstancePrefixes... I dont want to override Hostname property in Connection block. Is there is another way to do this? 

Thanks,
