Cause

When NCM is using an Orion Core structure where Additional polling engines are part of the environment, it is mandatory to install the Individual polling engine plugin on the Orion Additional Polling engines.  These are included in the Orion Additional Component Download and not the NCM installer download.

Resolution

  1. Download the Additional Polling Engine Installer from the SolarWinds Customer Portal.
  2. Save it on the Additional Polling Engine server for both the Core and the NCM additional Polling engine.
  3. On the server that is (or intended) to be an Additional Polling Engine, install the Orion additional Poller, if it is not already installed.
  4. Verify that the installation is completed and it is listed in the Settings on the Orion Web Console in the Details >Polling Engines.
  5. Register the Components that do not require a license and complete the Orion Configuration Wizard.
  6. Repeat this for all pollers.
  7. Verify a config can be downloaded for at least one device on each Orion Polling Engine.
