[doctor/master] Properly suppress staggered messages

commit 1bfdf45380ef0232bd563e18ccaaaeda9fd2b178 Author: Damian Johnson <atagar(a)torproject.org> Date: Sun Sep 28 12:14:28 2014 -0700 Properly suppress staggered messages We updated suppression times if and only if its duration had expired. Take the following scenario with the suppression time of six hours per message... 2:00 - issue A comes up 4:00 - issue B comes up At 4:00 an email is sent having both issue A and B, so the proper thing would be to suppress both until 10:00. However, message A's suppression time wasn't being updated so we'd email at both 8:00 and 10:00 instead. This should greatly cut down on the amount of noise since all messages have a default suppression time. --- consensus_health_checker.py | 95 ++++++++++++++++++++++++++----------------- 1 file changed, 58 insertions(+), 37 deletions(-) diff --git a/consensus_health_checker.py b/consensus_health_checker.py index 30693d5..54c50da 100755 --- a/consensus_health_checker.py +++ b/consensus_health_checker.py @@ -85,6 +85,27 @@ class Issue(object): return self._runlevel @lru_cache() + def get_suppression_key(self): + """ + Provides the key used for issue suppression. + + :returns: **str** used for the configuration key of this issue in the + suppressions file + """ + + if self._template == 'TOO_MANY_UNMEASURED_RELAYS': + # Hack because this message has too much dynamic data to be effectively + # suppressed.
