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.
