[Pkg-nagios-devel] Bug#686036: icinga: Upstream bug fixes for duplicate events

[Bernhard Schmidt]

Package: icinga
Version: 1.7.1-2
Severity: normal
Tags: patch

Hello,

upstream just released version 1.7.2, which fixes a highly annoying bug
causing duplicate events

| we learned by different sources (#2964, using mod_gearman, PNP rrdtool
| illegal update time) that a performance increasing change in Icinga Core
| 1.7.0 (#2182) was causing trouble on the event scheduling logic, causing
| duplicated events when rescheduling those. This resulted in duplicated
| (or even more) check events under various circumstances,  as well as too
| much performance data and more outputs. We’ve been testing various fixes
| in our development branches (#2676)

In my environment this is causing about 10k lines per hour of the sort

I patched icinga with the two upstream commits locally (see attached
patch) and it immediately solved my issue as well as reducing CPU usage
by 30%.

I'm not sure whether this could be a candidate for Wheezy at this time.
