Flapping in Icinga 2.8.0

The author viewing the code for the first time

Flapping detection is a feature many monitoring suites offer. It is mainly used to detect unfortunately chosen thresholds, but can also help in detecting network issues or similar. In most cases two thresholds are used, high and low. If the flapping value, which is the percentage of state changes over a set time, gets higher than the high threshold, it is considered flapping. It will then stay flapping until the value drops below the low threshold.

Icinga 2 v2.7.1 bugfix release

We’ve come around several issues with Icinga 2 v2.7.0 and fixed them with this new v2.7.1 release. It also contains other bug fixes requested by Icinga partners and their customer support (Livestatus, DB IDO downtimehistory).

There also was an issue with large configuration files being synced in distributed environments. Aside from the bugfix the configuration sync logs now tell you how many bytes will be synced for better debugging low bandwidth issues. Cluster setups could also run into the problem that the “Downtime End” event was not correctly updated in the IDO database history tables. (more…)
