Yeah I have one setup like this.
flow record netflow-input
description IPv4 NetFlow
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
collect transport tcp flags
collect interface output
collect counter bytes long
collect counter packets long
collect timestamp absolute first
collect timestamp absolute last

flow record netflow-Output
description IPv4 NetFlow
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface output
collect transport tcp flags
collect counter bytes long
collect counter packets long
collect timestamp absolute first
collect timestamp absolute last

flow exporter NTA_Exporter
destination x.x.x.x
source Vlan100
transport udp 2055

flow monitor NTA_Monitor
description IPv4 netflow ingress exports
exporter NTA_Exporter
cache timeout active 60
record netflow-input
interface TenGigabitEthernet1/0/1
ip flow monitor NTA_Monitor input
There are separate records for input and output, but then only the input record is applied to the flow monitor. Do you just run an additional monitor for output?
