SNMP monitor VPN traffic to ASA firewall

Unanswered Question
Aug 25th, 2008

From a Linux system, using the appropriate snmp command, I can get the traffic counters on any interface, so therefore I can monitor total traffic through any interface on the ASA 5520 firewall. No problem there.

$ snmpwalk -Os -c community -v 1 firewall.address | grep Octets

ifInOctets.1 = Counter32: 2387591805

ifInOctets.2 = Counter32: 3256166813

ifInOctets.3 = Counter32: 263478072

ifInOctets.5 = Counter32: 2954139109

ifOutOctets.1 = Counter32: 3995534498

ifOutOctets.2 = Counter32: 928367724

ifOutOctets.3 = Counter32: 2103539651

ifOutOctets.5 = Counter32: 2633864984

Now, there's a couple VPN tunnels terminated on this firewall. I would like to monitor, with SNMP, the traffic through the VPN tunnels. I can't find the place in SNMP where those traffic counters are.

I did an snmpwalk on that firewall and looked at the output, but couldn't find anything that may suggest any relation to VPN.

Can somebody shed some light please?

I have this problem too.
