Wireshark-users: Re: [Wireshark-users] Need to record bandwidth used by branch office VPN tunnels

I have a site with two branch offices. The branch offices
communicate back to the main office through Branch Office VPN
tunnels over the Internet.
If the office IP structure is:
Main - 192.168.1.x
Br1 - 192.168.2.x
Br2 - 192.168.3.x
Can I use Wireshark at the main site to record the traffic
coming to the main site from the remote sites over those VPN
tunnels in order to determine the current bandwidth used by
that traffic?
Can I do it without having to capture all the traffic (i.e.
can I report on the bandwidth the traffic is using without
having to capture that traffic)?
I would expect that I will need to capture stats for about
a week and don't want to have to save GB worth of wireshark
data, unless I have to, in order to accomplish this.
Thanks,

Gary,
Wireshark isn't the best tool for this kind of thing. See if your
routers support Netflow - there are both commercial and open source
products that can interpret Netflow records and provide you with
good accounting of your traffic usage.
If you need help with this then contact me off list for a quote to
get this set up using open source tools, or you could try rolling
your own.
