Enable debug-level logging for traps in IP domain

Products

• VMware Smart Assurance
• Network Observability

Issue/Introduction

• How do I see traps that are sent to a Smarts AM IP domain?

• How do I enable debug-level logging for Smarts AM traps like a "link down" trap?

Environment

All supported releases of Smart

Resolution

• Trap processing for Smarts AM is handled in the devstat-snmp-trap.asl ASL script found here:
  

  <BASEDIR>/IP/smarts/rules/devstat/devstat-snmp-trap.asl

• To enable debug-level logging for the traps in the Smarts IP AM domain log, run the following command:

  <BASEDIR>/IP/smarts/bin/dmctl -s <AM-PM Domain> put ICF_TopologyManager::ICF-TopologyManager::DebugEnabled TRUE

NOTE: DebugEnabled is hard coded in the discovery.conf file (<BASEDIR>/IP/smarts/conf/discovery/discovery.conf) to FALSE, so after any restart of the IP domain process, DebugEnabled will be set back to FALSE.

• To finalize the enabling of the trap debugging in the domain log do the following:

          Manually set DebugEnabled = FALSE in the discovery.conf file to TRUE and restart the IP domain process.

• You can also do the following that will allow for the enabling of trap debugging in the IP domain log, without having to restart the domain process.

  • Restart the internal trap driver with the following commands:

                  Stop the Driver:
                  dmctl -s <ip-domain> invoke GA_DaemonDriver::Devstat-Trap-Driver stop

                  Start the Driver:
                  dmctl -s <ip-domain> invoke GA_DaemonDriver::Devstat-Trap-Driver start

Additional Information

The trap output will appear in the IP domain log file in <BASEDIR>/IP/smarts/local/logs/<domain name>.log file and will look similar to the following:
