[c-nsp] cheat sheet for "new" netflow?

[Joe Loiacono]

Here's a quick basic FNF (from ASR 1000):

flow exporter PRIMARY_NMS
 description FNF export to Primary NMS
 destination 192.168.100.100
 source Loopback0
 transport udp 9996
 template data timeout 60
!
flow monitor MONITOR_V4
 description IPv4 netflow monitor
 record netflow ipv4 original-input
 exporter PRIMARY_NMS
 cache timeout active 900
 cache entries 200000
!
flow monitor MONITOR_V6
 description IPv6 netflow monitor
 record netflow ipv6 original-input
 exporter PRIMARY_NMS
 cache timeout active 900
 cache entries 200000
!
!For each interface ....
!
interface GigabitEthernet0/0/0 
 ip flow monitor MONITOR_V4 input
 ipv6 flow monitor MONITOR_V6 input
!
interface GigabitEthernet1/0/0
 ip flow monitor MONITOR_V4 input
 ipv6 flow monitor MONITOR_V6 input

I upgraded from 15.3 and 15.4 and saw my nfsen graphs flatline.

The upgrade helpfully removed all my netflow config, I suppose this is a 
subtle hint that I’m behind in my knowledge of the new way of doing 
netflow.

Any good, quick cheat sheets for the transition?  I have something cobbled 
together from CCO now, but my traffic levels look to be much lower in 
nfsen, so I’ve obviously botched something.

Thanks
