I have NetFlow running on a Meraki MX450. It is showing as gray/unknown and has last been up around 7 days ago but it obviously receives data as it is scanned every 15 minutes and the data updated. I have no idea what to do to make it become green/Up because I am very new with PRTG and I did not set it up. Also, I have no idea how to check if I have a remote probe installed which, I'm assuming has to be installed and already is installed in my case.
NetFlow sensor is showing up as unkown
