Alerts not working after NPM 12.0 RC upgrade

Updated September 7th, 2016



This has been resolved in DPA 10.1 SR1 which is now available in customer portals.

Steps to resolve:

  1. On Orion side, Settings -> Database Performance Analyzer Settings -> Set up DPA Integration -> Remove Integration
  2. Upgrade DPA to 10.1 SR1 from portal
  3. Re-integrate Orion and DPA


Customers are unable to receive any email notifications after updating NPM to a version 12.0 RC 1, 2, or 3.

Customers will get the following error when testing alerts NetObjectData is null

 Sample errors can be seen on the AlertingV2 and SWIS v3 logs:

  • NPM 12.0 RC1
  • NPM 12.0 RC2
  • NPM 12.0 RC3
  • DPA 10 


Problem was caused by a issue with DPA integration and SWIS Federation. This occurs if customer has DPA installed on same host as Orion. Removing DPA integration resolves the issue. 


  1. Stop all Orion services.
  2. Go to Start > Control Panel > Uninstall a program > "SolarWinds Orion-DPA Integration" > UNINSTALL.
  3. Complete Configuration Wizard.
  4. Stop SolarWinds Information Service v3 using Orion Service Manager.
  5.  Run the following query against customer's Orion database:

DELETE FROM FED_ProviderSubscriptions
DELETE FROM FED_Subscription
DELETE FROM FED_RemoteInformationServices

  1. Restart SolarWinds Information Service v3 using Orion Service Manager.
