collectd.java allows only single java application to graph

[wasfree]

Right now it is only possible to define Connection in java.con. This means e.g if you running zk and Kafka on same node you can't graph both applications.

Current Setup:

pillar.example
collectd:
  javalib: /opt/java/jre/lib/amd64/libjava.so
  plugins:
    java:
      jvmargs:
        - "-verbose:jni"
        - "-Djava.class.path=/usr/share/collectd/java/collectd-api.jar:/usr/share/collectd/java/generic-jmx.jar"
      host: {{ grains['id'] }}
      port: 28181


/etc/collectd.d/java.conf
    <Connection>
      ServiceURL "service:jmx:rmi:///jndi/rmi://example.host.com:28181/jmxrmi"
      Host "example.host.com"
      Collect "classes"
      Collect "compilation"
      Collect "garbage_collector"
      Collect "memory"
      Collect "memory_pool"
    </Connection>

Expected Setup:

pillar.example
collectd:
  javalib: /opt/java/jre/lib/amd64/libjava.so

      app1:
        host: {{ grains['id'] }}
        InstancePrefix "app1-"
        port: 28181
      app2:
        host: {{ grains['id'] }}
        InstancePrefix "app2-"
        port: 9999
