A Data Collector is showing as "Not Connected" in Performance Center console, even though the dcmd process is running and has been restarted

CA Performance Management, all versions

There is an issue with activeMQ, and restarting only the dcmd process may not resolve the issue


1. Stop dcmd, as follows; /etc/init.d/dcmd stop

2. Stop activeMQ, as follows; /etc/init.d/activemq stop

3. Delete or rename the "/opt/IMDataCollector/apache-karaf-2.4.3/data" folder (path may vary)

4. Start dcmd, as follows; /etc/init.d/dcmd start  (this will also start activemq)


The Data Collector should now show as "Collecting Data" in the CA Performance Center console
