This issue has been migrated from Redmine: https://dev.icinga.com/issues/11014

Created by tgelf on 2016-01-22 14:49:34 +00:00

Assignee: gbeutner
Status: Closed (closed on 2016-01-26 13:39:43 +00:00)
Target Version: 2.4.2
Last Update: 2016-02-23 09:58:44 +00:00 (in Redmine)

Icinga Version: 2.4.1
Backport?: Already backported
Include in Changelog: 1

The only way to run a safe environment when there are Icinga agents involved is to allow endpoint connections in only one directions, otherwise you'll get a mix of checks being executed twice the very same time, and eventually those check results being duplicated once again when sent upstream. Even more duplication takes place in case there are older connection threads hanging around for whatever reason. Or when multiple masters are involved - I found no way to work around that scenario.

Farther details have been shipped in a customer support issue, please feel free to ask in case additional information is required.

Cheers,
Thomas
