Alerts are received when there are no new events.

For example:

• Node is Down
• But alert re-triggers on the same node after period of 10 days

Network Performance Monitor

For NPM 11.0.1 [Core 2014.2.1] and older

The default value can be changed from 14400 minutes (10 days) up to a maximum of 129599 minutes (90 days).

1. Go to C:\Program Files (x86)\SolarWinds\Orion\AlertingEngine.exe.config.
2. Change the value setting in the following key from "14400" to "129599":
        ​<add key="AutoClearAlertIntervalInMinutes" value="14400" />
3. Save the file.
4. Restart Alerting Engine using Orion Service Manager:
   1. Open Orion Service Manager [Start > SolarWinds Orion > Advanced Features > Orion Service Manager].
   2. Select SolarWinds Alerting Engine.
   3. Click Restart.

 

NPM 11.5 [Core 2015.1] and newer

The default value can be changed from 10 days up to a maximum of 100 days.

Run the following query against your SQL DB using Database Manager or SQL Server Management Studio.

UPDATE Settings SET CurrentValue = '144000' WHERE SettingID = 'AlertEngine-AutoClearAlertIntervalInMinutes'

This will increase the re-trigger interval to 100 days.

Cause 

Alert was triggered - The alert was reset and the conditions set are triggered.There are three scenarios that will cause an alert to re-trigger:

• Within the Alerting Engine we have auto-clear of acknowledged alerts functionality. This means Alerting Engine clears acknowledged alerts and re-triggers them again (if trigger condition is still true) when triggered alert is in acknowledged state during last 10 days (default value).
• If you manually clear an Acknowledged alert from the Active alerts window, and the object being monitored still meets Trigger Condition.
