Hello Adrian,

 

Here's what I use. I'm sending the netflow data to port 9995 on the
machine named inside-nagios on the inside interface. I'm sending netflow
data for all traffic on all interfaces. 

 

flow-export destination inside inside-nagios 9995

flow-export template timeout-rate 4

 

access-list global_mpc extended permit ip any any

 

class-map global-netflow

match access-list global_mpc

class global-netflow

  flow-export event-type all destination inside-nagios

Subject: Re: [Nfsen-discuss] nfdump not showing correct time

 

Hello David, 

Sorry - I can't help you with your problem, but I have a small request -
Can you show me the netflow configuration template you used on the ASA
device in order to export flows? I have been trying to export flows from
an ASA but I failed because of lack of experience with the device. :)

Thanks,
Adrian

Hello,

I got nfsen installed and running without too much problems, it looks
like it will really be helpful, but I'm only seeing Flow graphs. The
Packet and Traffic graphs are all empty.

I'm using one device, a Cisco ASA 5510, sending all events, and sending
templates every 4 minutes. Running nfsen under openSUSE.

I suspect my problem is that nfdump is not showing the correct date/time
on the flows. And it's not just off my a few hours, it's off by over a
month. It thinks today, December 15, is October 29. The date/time is
correct on the ASA and the linux box, they sync from the same ntp
source.

Is there some issue with an ASA and openSUSE using different unix time
bases?
