Overview

An alert is re-triggering on an interface down even though the interface has been down for a while and did not go up.

Product section

Network Performance Monitor

Cause

When an alert is triggered, our software has a time limit which triggers the alert again when the set limit was met.

Resolution

To change this value you could update the following application setting value within the AlertingEngine.exe.config file:

Go to install directory (by default) C:\Program Files (x86)\SolarWinds\Orion.
<add key="AutoClearAlertIntervalInMinutes" value="14400" /> Max allowed value of this setting in minutes is 144000 - which is about 100 days.
Restart Alerting Engine service.

In newer versions of NPM this setting has been moved to the database in the settings table: -AlertEngine-AutoClearAlertIntervalInMinutes
