## Alarme de facturation
Dans l'exemple suivant, Amazon CloudWatch envoie une notification par e-mail lorsque les frais prélevés sur votre AWS compte dépassent le seuil d'alarme. Pour recevoir des notifications d'utilisation, activez les alertes de facturation. Pour plus d'informations, consultez la section [Créer une alarme de facturation pour surveiller vos AWS frais estimés](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/monitor_estimated_charges_with_cloudwatch.html) dans le *guide de CloudWatch l'utilisateur Amazon*. >

## Récupération d'une instance Amazon Elastic Compute Cloud
L' CloudWatch alarme suivante permet de récupérer une instance EC2 lorsque le contrôle de statut échoue pendant 15 minutes consécutives. Pour plus d'informations sur les actions d'alarme, consultez la section [Créer des alarmes pour arrêter, arrêter, redémarrer ou récupérer une instance EC2](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/UsingAlarmActions.html) dans le *guide de l' CloudWatch utilisateur Amazon*.
