How to use Support Logs

Hello,

I am developing an application for the HP VAN 2.6 controller, the application works well but I am unable to log anything at all on the 'Support Logs' section of the controller GUI and makes it difficult to debug. Following the Developer Guide I can see that using a logger works almost out-of-the-box via slf4j, but again, I am unable to make this work. Here's part of the code that I am using (taken from the bl folder of my app):

public class ArpMirrorManager implements ArpMirrorService, SequencedPacketListener {

	/* Service dependencies */
	@Reference(policy = ReferencePolicy.DYNAMIC,
	cardinality = ReferenceCardinality.MANDATORY_UNARY)
	private volatile ControllerService controller;
	
	private static final Logger logger = LoggerFactory.getLogger(ArpMirrorManager.class);

Here are some places where I am trying to log information whenever an event ocurs:

	@Activate
	public void activate(){
		controller.addPacketListener(this, PacketListenerRole.DIRECTOR, DIR_ALTITUDE, INTEREST);
		logger.info("Module ARP Mirror activated");
	}

	
	@Deactivate
	public void deactivate(){
		controller.removePacketListener(this);
		logger.info("Module ARP Mirror deactivated");
	}

	
	@Override
	public void event(MessageContext context){
		logger.info("ARP MIRROR: Packet IN event");
                /* Some more code dealing with the PKT IN*/
                ....
         }

Am I missing something? Where can I access the logged messages?

Thanks,

Sergio

Hi Sergio,

Do your log messages show up in the raw log file? It is located at /var/log/sdn/virgo/logs/log.log.

If your class is attempting to be loaded via dynamic OSGI referencing, be sure to include something like the following before the class definition:

@Component(immediate = true, metatype = true)
@Service
