how to check traffic volume in IPSec tunnel

[DavidLaita]

Is there any way to check the volume of traffic through an IPSec tunnel? We're being notified of spikes in volume through a tunnel but I'm not sure if there's a way to run a report or check metrics related to tunnel traffic.

Hi @DavidLaita ,

You should be able to use the graph tool as explained here... the article and graphics seem a bit dated but should still be applicable:

Graphic Traffic Monitoring for Interfaces - QoS Statistics

Hope it helps,

For live graph you can use built in QoS statistics as @kiwi mentioned.

For historic data you need to set up SNMP based monitoring.

SNMP monitoring app can then send alerts according to thresholds.
