Trigger alert conditions are missing

Table of contents

Updated December 12, 2016


When editing alerts, it would show that the Trigger Conditions are blank or empty. As most alerts starting NPM 11.5 are web based, this usually happens if the IIS feature gets corrupted and needs to be recycled.

Alerts would still work as intended but you will not be able to edit it.


  • NPM 11.5.x
  • Orion Core 2015.1.x


  1. From the Orion server, open the command prompt as an administrator.
  2. Type "iisreset" and press Enter.
  3. Clear cache from your web browser and test again.
