Managing alarms

Alarms you create in the Amazon Redshift console are CloudWatch alarms. They are useful because they help you make proactive decisions about your cluster or serverless instance. You can set one or more alarms on any of the metrics listed in Monitoring Amazon Redshift using CloudWatch metrics. For example, setting an alarm for high CPUUtilization on a cluster node helps indicate when the node is overutilized. An alarm for high DataStorage would keep track of the storage space that your serverless namespace is using for your data.

From Actions, you can modify or delete alarms. You can also create a chime or slack alert to send an alert from CloudWatch to Slack or Amazon Chime by specifying a Slack or Amazon Chime webhook URL.
