Description

We were talking today about how to compare bandwidth authorities, and make sure that different implementations are producing similar figures.

One easy way to compare bandwidth authority implementations is to compare their total bandwidth weights.

For example, this is the total bandwidth weight in the consensus:

$ cat Library/Application\ Support/TorBrowser-Data/Tor/cached-microdesc-consensus | grep "^w" | cut -d= -f2 | grep -v Unmeasured | paste -s -d + - | bc
43763163

Do you think we can do a graph of total bandwidth weight for votes?
Should this go somewhere on metrics?
Or should it be a once-off thing that Tom (or someone else) does?

This should start as a once-off thing. I'll make a first graph in the next few hours and post it here.

Here's a graph showing total consensus weights across bandwidth authorities in March 2018:


Let me know if you want something else or another graph for a longer time frame (like all of 2018).

Thanks, this is interesting.

I'd like to see a graph from the "normal state" around September? 2017, through the DDoS in December and failure in February.

Sure, that'll take a while. I'll post the graph as soon it's ready.

Here's a new graph covering the time between July 2017 and today:

Thanks!
For reference, we'll use this graph in the scaling part of the bandwidth authority session org/meetings/2018Rome/Notes/BandwidthAuthorityRequirements
