Overview

Once adding a new Netpath probe, it shows a "First poll not yet complete" message.

 

 

In the Netpath log (C:\ProgramData\SolarWinds\Logs\NetPath), it shows the following error:

 

ERROR SolarWinds.NetPath.Pollers.CommonPollerBase`2 - (null)  Exception in processing job.
SolarWinds.NetPath.Shared.ErrorCodes.NetPathException: Exception of type 'SolarWinds.NetPath.Shared.ErrorCodes.NetPathException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.

Cause

The NetPathAgent.cfg file stored in C:\ProgramData\SolarWinds\Orion\NetPath folder is corrupted or with 0 size.

Resolution

Follow the steps to fix the corrupted NetPathAgent.cfg file:

 

  • Check the NetPathAgent.cfg file from C:\ProgramData\SolarWinds\Orion\NetPath\
  • The size should be, by default, 2KB.
  • If it is empty (0kb), delete the file.
  • Restart the SolarWinds Services.
  • The file will be recreated with a 2KB size.
  • NetPath Probes will start to display data after successfully polling.
