Additional Poller down and all services are running

Updated 11-21-2018


When attempting to move nodes from the main poller to the additional poller, you find that the Additional Poller is down. This is also confirmed on the Polling Engines web page. However, the Orion Service Manager on the Additional Polling Engine shows that all services are up.


The BusinessLayerHost.log on the Additional Poller indicates that not all plugins were started and there was an error message indicating problems in the CoreBusinessLayer. The Core.BusinessLayer.log shows the following message:  


Source entity [Orion.Package] not found in catalog (Fault Detail is equal to InfoServiceFaultContract [ SolarWinds.Data.Query.EntityNotFoundException: Source entity [Orion.Package] not found in catalog


  • Orion Platform 2017.3 HF 5
  • Orion Platform 2018.2




  1. Use Orion Service Manager to stop services on the Additional Polling Engine.
  2. On the Additional Polling Engine, back up the C:\Program Files (x86)\SolarWinds\Orion\Information Service\3.0\ folder.
  3. Copy the contents of C:\Program Files (x86)\SolarWinds\Orion\Information Service\3.0\ folder from the main poller to the Additional Poller at the same file location.
  4. Start all services.
