Debugging problems with device type overrides in CA Performance Management

Issue/Introduction

CA Performance Management provides a method where the discovered devices can be set to use different Device Type assignments than the product uses by default.

We Override the Device Types and Context Types by editing the DeviceTypes.xml file on the Data Aggregator.

If this isn't working as expected we can enable debug to track the messaging for the function in search of a cause.

Environment

All supported Performance Management releases

Resolution

To enable this debug complete the following:

1. Edit the /opt/IMDataCollector/apache-karaf-2.4.3/etc/org.ops4j.pax.logging.cfg file. 
2. Add the following lines to the file:
   • log4j.logger.com.ca.im.dm.certs.snmp.DeviceTypeServiceImpl=DEBUG,DiscoveryLog
   • log4j.logger.com.ca.im.dm.certs.snmp.SNMPDeviceServicesFunction=DEBUG,DiscoveryLog
3. Reproduce the issue and provide CA Remote Engineer (CARE) re.sh script output from the CA Data Collector server. 

To disable the debug comment out (use # symbols) or remove the new lines from the org.ops4j.pax.logging.cfg file and save the changes.

Additional Information

This is debug that was first introduced in the GA r3.6 release and the r3.5 April Monthly Update kit. It is available in all releases newer than that.

NOTE: CA Remote Engineer (CARE) re.sh script instructions can be found in the r3.7 documentation here:
