Option to perform tests on specific interfaces?

[shaperilio]

I landed here via internet-pi.

I currently have multiple Internet providers as they appear to be intermittently unreliable. Before I embark on a bonding experiment, I figured I'd check on their quality / see how often and for how long each one goes bad.

What would it take to be able to run speed tests through specific interfaces? I suppose it may be easiest to have a dashboard for each one, though perhaps a dashboard for comparing results from each interface would also be useful.
