The consensus-health checker rate-limits warnings to reduce the noise. See this part in the code: https://gitweb.torproject.org/doctor.git/blob/HEAD:/src/org/torproject/doctor/StatusFileReport.java#l89 For example, a message "The following directory authorities did not return a consensus within a timeout of 60 seconds: $authorities" won't be repeated in the next 150 minutes. Ideally, I'd want to reduce volume of consensus-health messages even more, for example, using #9103. So, the idea behind consensus-health messages is to get a notification of *current* problems, not at all to investigate problems in the *past*. You'll want to use Atlas or relay-search or the descriptor archives for that. So, how to check the checker? Fine question! One solution might be to run a second checker. Want to do that and report problems that the first checker overlooked? In theory, setting up DocTor is easy: https://gitweb.torproject.org/doctor.git/blob/HEAD:/README Best, Karsten _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
