 We can see if #28547 helps us work out why relays are not being measured.
 But if relays are never measured, we will need to implement this ticket to
 see them in the v3bwfile.

 at to search for this type of information?.

 Torflow does not provide much diagnostic information per relay.
 sbws need to provide better information, so we can fix the bugs that make
 it worse than torflow.

 The votes provide a small amount of information, it is available in
 consensus-health in the big relay table:
 https://consensus-health.torproject.org/consensus-
 health-2019-03-13-10-00.html#000A10D43011EA4928A35F610405F92B4433B4DC

 There are bw and bwauth lines for each relay in consensus-health.

 > If we add them, just without `bw` key so that Tor doesn't parse it,
 relay operators will see their relay, but still might question why it is
 not `measured` in the consensus.

 We have this ticket so we can answer the questions that relay operators
 ask when their relays are not measured.
