Hi Damian and Tom,
Roger discovered that dannenberg did not include any exit flags in certain votes anymore [1].
It would be great if we would detect and notify about such events in the future.
I see two places where this could be added:
DocTor: a new check that alerts on events where a certain dir auth does either no longer include certain flags (guard, hsdir, exit, ..) at all or better: if the amount of relays with a certain flag significantly dropped by xx % from one vote to the next.
consenus-health graphs: we have nice graphs per dirauth and bwauth, if we would have per-dirauthvote-per-flag (mainly guard, exit, hsdir - we have already running) graphs as well we could spot such events (and even trends) better. (btw: what caused there recent flat-line in graphs on 2018-02-03 - 2018-02-05)
What do you think?
thanks for considering it, nusenu
