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
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
acknowledgment is cleared and Watcher resumes executing the watch’s actions normally.
