ProductClientMBean (pdl API)

All Known Implementing Classes:

ProductClient
```
public interface ProductClientMBean
```
Used to define JMX monitoring interface. The init script command should be modified to include the following arguments:
- -Dcom.sun.management.jmxremote=true
- -Dcom.sun.management.jmxremote.port=11237
- -Dcom.sun.management.jmxremote.ssl=false
- -Dcom.sun.management.jmxremote.authenticate=false
Then this can be accessed on the command line using the Syabru nagios jmx plugin: http://snippets.syabru.ch/nagios-jmx-plugin/
```
 java -jar check_jmx.jar \
        -U service:jmx:rmi:///jndi/rmi://localhost:11237/jmxrmi \
        -O ProductClient:name=jmx \
        -A ListenerQueueStatus
 
```
Where the service url is updated for the correct host and port, and the Attribute is one of the "get" methods without the word "get".
