Overview

  • A Node even after assigning it from an Additional Polling Engine to the Main Polling Engine (or vis-a-vis) still showing failed SSH login attempts from the previous Polling Engine.
  • Stopping the SolarWinds Job Engine Service on the Polling Engine in question also stops the failed SSH login attempts.
