NetFLow config for Cisco Nexus NXOS devices?
I had a netflow config on my Nexus 7004's on NXOS that worked with Scrutinizer, but it not sending templates I guess to LM so it will not see them.

Unfortunately, the documentation is a bit limited -- improved since the old days, but there is only one example -- the very popular and modern Cisco 3745 router with original Netflow. LM should have a maintained library of examples.
Regardless, the required field list is there (assuming the documentation is accurate). If you can't define a suitable record, get a capture and open a support case with LM to find out what changes to the record are needed to make it work.
Yeah, that one surprised me too. The TAC seemed to have no ready examples available. I do have a ticket open for this now.
It was showing in the debug console as data coming in, but no templates showing up.
