1. Use JConsole to open the Java Monitoring and Management Console. You can also run JConsole to monitor a specific process ID for your application: jconsole PID. Or you can run JConsole remotely using: jconsole hostname:port. 
    $ jconsole
    Note: If SSL is configured on the JMX Connection Handler, you must specify the Directory Proxy Server jar file in the class path when running jconsole over SSL. For example, run the following jconsole command:
    $ jconsole \
  -J-Djavax.net.ssl.trustStore=/path/to/certStores/truststore \
  -J-Djavax.net.ssl.trustStorePassword=secret \
  -J-Djava.class.path=$SERVER_ROOT/lib/PingDirectoryProxy.jar:/Library/Java/JavaVirtualMachines/jdk-version.jdk/Contents/Home/lib/jconsole.jar
  2. On the Java Monitoring & Administrative Console, click Local Process, and then click the PID corresponding to the directory server.
