Description

https://metrics.torproject.org/dirbytes.html
shows that on average about 1gbit/s is spent serving directory information.

But the investigations in #33018 show that moria1 by itself is pushing about 135mbit/s, and I hear gabelmoo is doing even more than that.

The text under the graph says "directory mirrors", so maybe we are leaving out dir auths in this graph? In that case, it would be cool to change it to one of those layered graphs so you can see how much of the total is dir auths and how much of the total are other relays.

Or maybe we're somehow not adding up the right things? Step zero is to spot-check the current data and the current graphs and become convinced that indeed we're presenting the right data.

The graph leaves out directory authorities, as the text indicates. Turning this into an enhancement rather than a defect, because the code is doing what it's supposed to be doing.

I'll see whether we can change the graph. The biggest blocker is that we'll have to reprocess the archives. Otherwise the directory authority numbers will suddenly jump from 0 to $bignumber which would probably cause a lot of confusion. But that reprocessing can happen in the background somewhere. Maybe it's a simple code change.
