Comment 3 for bug 1372818

Yes, for me "feature" is the L3 metering driver.

The admin has a problem: metering traffic for his projects/users. At the time (two years ago) I configured it successfully, meaning I could stare at a table full of numbers, but I had no idea what those numbers meant, on which interface they were measured, what kind of traffic was measured or if it measured only external traffic or inter-tenant or both.

So my suggestion is: take a simple example, one that an admin can relate to, like measure internet-bound traffic for project X, and show how to get that measurement.

It could also be that in two years it is now simpler to configure and understand, I haven't tried it since. (we rely on non-openstack metering)
