> The global repeat tolerance value for all alert definitions is set on the
> cluster-env configuration. Unless an alert definition overrides this value,
> it will be used for any definition in the system. By default, this value will
> be set to 1, indicating that there is no tolerance and the alert state should
> be taken at face value.

> *UI Warning of Delayed Alerts*
> When changing the value of the global of definition-specific repeat
> tolerance, a warning should be presented to the user to indicate that it will
> now take longer for the alert notifications to be sent. This is because
> notifications are delayed until the interval multiplied by the repeat
> tolerance is reached. Consider the case where the check against an alert
> happens every 5 minutes and the repeat tolerance is set to 5. It will be at
> least 25 minutes before any outbound notifications are dispatched. This
> warning can be on a per-alert definition basis as well as when setting the
> global value.
