JConsole Agent

1. Add following section to your JAVA_OPTS property:

export JAVA_OPTS="-Dchoreo.connect.jmx.metrics.enabled=true -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=11111 -Dcom.sun.management.jmxremote.rmi.port=9999 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=0.0.0.0"

2. Add port mapping to enforcer:

  enforcer:
    ...
    ports:
     ...
      - "9999:9999"
      - "11111:11111"

2. Run jconsole(in your java home /bin directory) and connect to localhost:11111 or service:jmx:rmi://localhost:11111/jndi/rmi://localhost:9999/jmxrmi.

2. Add the above jar to the enforcer droppings location.

3. Add following section to your JAVA_OPTS property (Use the exact name of the jar you added to the droppings replacing jolokia-jvm-1.7.1.jar):

export JAVA_OPTS="-Dchoreo.connect.jmx.metrics.enabled=true -javaagent:/home/wso2/lib/dropins/jolokia-jvm-1.7.1.jar=port=7777,host=0.0.0.0"

4. Add port mapping to enforcer:

  enforcer:
    ...
    ports:
     ...
      - "7777:7777"

5. Try following URLs in the browser:

View ext auth service metrics
http://localhost:7777/jolokia/read/org.wso2.choreo.connect.enforcer:type=ExtAuthMetrics
