I have a few linux servers with multiple subinterfaces for IP addresses, but only 1 physical interface.
I'm trying to find a way to view traffic statistics for these subinterfaces, but /proc/net/dev only shows physical interfaces plus the loopback.
Is it possible to include subinterfaces into /proc/net/dev?
If not, how can I do traffic reporting for subinterfaces? (I want to keep each subinterface separate in the reports)
