Flapping occurs when a monitored object (ie: a service or host) changes state too frequently, making the cause and severity of the incident unclear. Flapping can be indicative of configuration problems (ie: thresholds set too low), troublesome services or real network problems.
When an alert changes states frequently, it may generate numerous events that are not immediately actionable.
In BigPanda, an incident enters the flapping state when one or more of the related alerts are flapping. By default, an alert is considered to be flapping when it has changed states more than 4 times in one hour. Contact BigPanda support if you need to configure custom logic (number of state changes within a period of time) for your organization or for a specific integration.
When an incident enters the flapping state, all subscribed users are notified and no additional state change notifications are sent. Subscribed users still receive a daily email reminding them about the incident. An incident exits the flapping state when all related alerts stop flapping (no longer meet the criteria for number of state changes in a period of time). BigPanda checks the flapping criteria every 15 minutes.
