On the first view looks your configuration fine. Do you get any data on the collector server?

Could you check with wireshark (or similar) what kind of data you get?

Please note that netflow doesn't contain the payload, so all the packets are way smaller.

One command that I don't see in your output, but which I once needed on 12.2.33SXH5 is:

mls nde sender

That actually turns on netflow export.

i added mls nde sender now i can see graph but traffic its polling is very less like 50 k avergae its a broadcast switch so it must show type of application and traffic but it only shows ssh traffic statistics

I am not sure what you try to tell me.

Can you make a show int vlan 219 and also a show int vlan 31?

Do those two interfaces actually show more than those 50k traffic?

I am not an expert on this, but I think you cannot enable netflow on trunk interfaces so if the int t1/1 is a trunk port that may be the reason it is not giving you an option to enable netflow there.
