Resolution:
1) In the Monitoring tab of Adapter Administrator, choose "Hawk" sink and click on "+" ( Add New Item ). Specify a hawk sink name and give the microagent name as follows "COM.TIBCO.ACTIVEDB.&ltagentid>". Add the required roles "INFO"/"WARN"/"ERROR"/"DEBUG". Apply the changes.

2) Start the adbagent. Start Hawk Display and invoke the "_onUnsolictedMsg()" method of COM.TIBCO.ACTIVEDB.&ltagentid> microagent. You should be able to see the last unsolicited message sent by ADB, if any.

If you are not seeing any messages after subscribing to this method please publish some messages out of this adbagent instance and try.
