WPM error: Plugin failed to start on polling engine

Updated January 11, 2017

Overview

This article addresses the issue where the WPM business layer does not start and the following error is found in the SEUM businesslayer log file:

File name: 'C:\Program Files (x86)\SolarWinds\Orion\SEUM\SEUMResourceConfig.xml'
   at System.IO.Error.WinIOError(Int32 errorCode, String maybeFullPath)

2016-12-07 20:17:15,644 [Scheduler] ERROR SolarWinds.SEUM.BusinessLayer.SEUMBusinessLayerPlugin - Unable to create missing application subviews.

 

Environment

NPM 12.0 and later

Cause 

This occurs when WPM is looking for a file on the additional polling engine that it cannot find.

Resolution

Copy the missing file from the primary server to the additional polling engine.
Note: In this case it was looking for C:\Program Files (x86)\SolarWinds\Orion\SEUM\SEUMResourceConfig.xml.
