What does "EMF2 PlugIn DEVICEIO not found" mean on Windows Netprobe logs

This is because DeviceIO sampler Plugin is attached to a Managed Entity belonging to a Windows machine. 

The error bellow will be found in the netprobe log:

As referenced in our DeviceIO documentation "This plugin is currently supported on Linux and Solaris platforms only, not for Windows ones."

Solution
