Problem with Sheriff-o-Matic


For the following build
https://uberchromegw.corp.google.com/i/internal.client.clank/builders/release-phone/builds/1125

Sheriff-o-Matic spammed me for every test stage that failed, in normal cases where there are different reasons for the different failures this is great, but in this case, where all the tests were failing because of the same issue (disconnected devices, see log trace below), Sheriff-o-Matic spammed me unnecessarily.

I understand that it is probably super difficult to detect what went wrong for a certain build step so I'm not really expecting this bug to be fixed :/ but if you have any suggestions on how to make this less annoying that would be appreciated (maybe see some kinds of failures, such as devices not being connected, as build-stopping or something).
