How do I alert or notify myself of a NCM configuration change on a device?
Unfortunately, Traverse is currently unable to correlate a detected change in a backup configuration and create an actionable event or trigger an event to notify the user. However, one possibility of being able to monitor or keep track of configuration changes within your devices may be to use the REPORTS > ADVANCED > CONFIG MGMT > Configuration Change Summary report (selecting each device and enabling the 'Include Diff' parameter. You can set up a daily/weekly/monthly scheduled (emailed) report for this after saving the report parameters.
Note that should no change be detected when the report is run, it will display "Unable to get device configuration difference data."
