NetFlow sensor is showing up as unkown

Votes:

0

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.

Hello,

in order to find out if proper and compatible NetFlow packets are arriving at the PRTG host, please use our NetFlow Tester: https://www.paessler.com/tools/netflowtester

Please make sure that the actual NetFlow Sensor configured in PRTG is paused indefinitely while testing. Please check if the incoming flows carry volume data (last number).

Arne, Thank you so much for your response. I ran the test and one template sat for a couple of seconds in the unassigned flows column but then moved its way to the templates received column with another one following, so I have a total of two templates. The incoming flows also all carry volume data. Is there anything else I should try to resolves this issue?

Hello,

in that case please contact us at [email protected]. Send a description of the issue and attach screenshots of the sensor (overview tab, settings tab) and of the tester.

We might need further information, but that would be a good start.
