After a condition is met, the alert goes into the **Pending** state.

If the condition remains active for the duration specified, the alert transitions to the **Firing** state, else it reverts to the **Normal** state.

You can set the minimum amount of time that an alert remains firing after the breached threshold expression no longer returns any results. This sets an alert to a "Recovering" state for the duration of time set here. The Recovering state can be used to reduce noise from flapping alerts. Select "none" stop an alert from firing immediately after the breach threshold is cleared.

1. Turn on pause alert notifications, if required.
|

|
||||
You can pause alert rule evaluation to prevent noisy alerting while tuning your alerts.
|
||||
Pausing stops alert rule evaluation and doesn't create any alert instances.
|
||||
This is different to [mute timings](ref:mute-timings), which stop notifications from being delivered, but still allows for alert rule evaluation and the creation of alert instances.
