I work for a Network analytics product company and I've heard several of our customers wanting to bring in some type of flow, preferrably IPFIX from aruba.
Our customers tend to have Cisco gear but also Aruba wireless and they want to be able to correlate the flow data.
I think we're unique in that we do it visually in a topology so getting flow data from the various devices helps with path analysis and correlating stats.
Also if the controllers can export things like identity based on authentication really helps troubleshooting.
Anyways, it would be great to get flow from Aruba if possible for our customers.
