Hi,
We have an issue that the internet is statured on a FTD.
It doesn't seem FMC tools can help figure out what causes it. Or I did not find the right place to look into it yet.
Could you advise?
Thanks

Exporting Netflow data from your FTD is the best way to visualize and analyze the usage of your system on a per-user (or per-address actually in most cases) basis. I have used the free PRTG version for such cases before.

Thanks, Can we export Netflow data via outside interface?
Is is possible if you send a link for that?
Thanks

Netflow data is exported from the diagnostic interface. However that traffic can be routed in your network back though the inside to the outside.

Hi,
I tried to set up netflow on an ASA in another city, outside interface. And export it to my home lab (99.x.x.22). I use PRTG in my lab. It did not work yet. Do you think it is ASA config need to check ?
flow-export destination outside 99.x.x.22 5555
flow-export template timeout-rate 15
flow-export delay flow-create 60
class-map flow_export_class
match any
policy-map global_policy
class flow_export_class
flow-export event-type all destination 99.x.x.22
service-policy global_policy global
Thanks

Check using the command "show flow-export counters". If that indicates flow records are being sent (run it more than once to see the number increment) then check a packet capture at the ASA (and possibly the PRTG server) to make sure the records are leaving the ASA outside interface and arriving at the server.
