Watch Acknowledgment and Throttling

edit

Watcher supports both time-based and acknowledgment-based throttling. This enables you to prevent actions from being repeatedly executed for the same event.

By default, Watcher uses time-based throttling with a throttle period of 5 seconds. This means that if a watch is executed every second, its actions are performed a maximum of once every 5 seconds, even when the condition is met. You can configure the throttle period on a per-action basis, at the watch level, or change the default throttle period in elasticsearch.yml.

Acknowledgment-based throttling enables you to tell Watcher not to send any more notifications about a watch as long as its condition remains true. Once the condition evaluates to false, the acknowledgment is cleared and Watcher resumes executing the watch’s actions normally.
