Cisco WLC Netflow

Has anyone had any luck getting the netflow sensor to work with their Cisco WLC?

I have a Cisco 2500 series wireless controller that I have added into PRTG using the custom recommend cisco template. The template lists all my AP's ssid etc. Today I attempted to add in a NetFlow sensor in order to capture the advanced metrics that I am looking for. However for the life of me I can not get the top talkers, connections or protocols to output the expected data. I am repeatable greeted with a gray circle of 100 % "other". The total amount does indeed fluctuate and the sensor it self is green which leaves me to believe it is indeed communicating with the WLC.

I should also note i'm currently using the NetFlow V9 sensor but also had the same results with NetFlow V9 (custom) sensor

If anyone knows a trick to get this working I would be internally grateful and owe you a virtual set of cookies :)

Well, I have a 2500 flying around here - but we don't use PRTG on it cause we have a Cisco Prime. But I do NetFlow with other Cisco devices and PRTG.

In any case - one thing about NetFlow sensors - you need to set it up and let it be at least a few minutes - I would recommend an hour - then you will see data.

The reason is simple - NetFlow is a "over time" thing - it takes time that this interpretation can happen.
