Decide on the way to represent metrics spanning multiple files

I put a gist here https://gist.github.com/mwalzer/a745e7845bfde73f12a6fee09e5f23f5

Resolution after discussing on monthly call: go forward with snippet no.2

[bittremieux]

I didn't include this in my notes about last month's call, but what was the reason to pick option 2 over option 3? Shouldn't we prefer having the unit in there, just like for simple metrics in our examples? (Although the unit for those specific values in the gist probably shouldn't be fraction.)

For the sake of keeping it in line with the single file metrics, yes. I have a more detailed example for the call.
