Summary

After putting Relator with DeviceMagic Rule into production, Relator runs fine by verifying Relator Trace Log

However, the port status of monitored switches never shows up in Device and Ports

The following line can be seen throughout the log file after further checking of the service log:

   Internal trace is dumped to ‘SN_SVC_LOG_EXCEPTION_TRC.TXT’

The service log also contains the following line when service starts:

The issue has been addressed in Argent AT 5.1A-1907-A

Technical Background

The issue is caused by coding error

Due to the exception error, the port status and bandwidth information could not be saved into database

As a result, Devices and Ports also show switches in gray as never being monitored

Resolution

Upgrade to Argent Advanced Technology 5.1A-1907-A or above

For users who cannot upgrade immediately, they can change registry

‘NO_TRAP_LISTENER’ value from 1 to 0
