Closed, ResolvedPublicPRODUCTION ERROR

Description

We should setup new shinken checks in beta that mirror the icinga error-rate alerts in production. This would hopefully catch more errors pre-production.

The log errors project is for actual errors, not infrastructure to deal with them.

Actually there's an "Improvements" column in Wikimedia-production-error for exactly this sort of thing :)

That is nice! https://gerrit.wikimedia.org/r/304263 managed to get an alarm overnight on beta-cluster alerts https://lists.wikimedia.org/pipermail/betacluster-alerts/2016-November/023912.html

Subject: [Betacluster-alerts] PROBLEM alert - Graphite Labs/Mediawiki Error Rate is CRITICAL
Notification Type: PROBLEM

Service: Mediawiki Error Rate
Host: Graphite Labs
Address: graphite-labs.wikimedia.org
State: CRITICAL

Date/Time: Thu 24 Nov 00:07:02 UTC 2016

Additional Info:

Graphite shows the error rate being 0 for the last 24 hours, so the alarm should NOT have triggered

I guess the check_graphite_threshold command fails on the Shinken host.
