You will associate anti-flooding policies with sending policies to make use of them. The default anti-flooding policy dictates that a single alert may be distributed to any recipient up to five times over the course of one hour and, if it persists, a reminder is sent after another hour passes. You can use this rule, called default AF, edit it, or you can create additional policies as needed.

Devo internal mechanisms Triggered alert discarding → Apart from explicit anti-flooding policies, Devo possesses an intrinsic anti-flooding system that offers an additional layer of protection against alert flooding. Alerts will be discarded after receiving 100 in every five-minute period. This system is always active but becomes especially useful when no anti-flooding policy is selected because setting one will create a more restrictive environment that will make it impossible to reach the conditions to activate this system. Alert definition deactivation → Devo also has an internal mechanism called AlertRateChecker, which shields you from extreme cases of alert flooding. It deactivates alert definitions upon exceeding a TREND of 100 given TREND or SPIKE. Even though they can be configured, the default TREND is 100 alerts per minute several times in every five-minute period, or a SPIKE of 5000 and the default SPIKE is 5000 alerts in a single minute. |
