Resolution

Resolution:

1. Check /opt/IMDataCollector/apache-karaf-2.4.3/etc/com.ca.im.dm.core.collector.cfg to confirm that all settings are correct
2. Stop the data collector: service dcmd stop
3. cd /opt/IMDataCollector/apache-karaf-2.4.3/etc and modify the configuration as necessary
4. Start the data collector: service dcmd start

 

Additional Information

• The /opt/IMDataCollector/apache-karaf-2.4.3/etc/com.ca.im.dm.core.collector.cfg is the main data collector configuration file.  The above procedure assumes settings in the com.ca.im.dm.core.collector.cfg are correct.  If settings are incorrect, they should be changed as needed
• The data directory will be rebuilt upon restart of the data collector so nothing is lost
