This may also result in that an OK notification not being sent if alert transitions from `No Data -> Pending -> OK`.
 
 
 
 If an alert rule has a configured `For` and the query violates the configured threshold it will first go from `OK` to `Pending`. Going from `OK` to `Pending` Grafana will not send any notifications. Once the alert rule has been firing for more than `For` duration, it will change to `Alerting` and send alert notifications.
