Updating Health Checks When You Change CloudWatch Alarm Settings (Health Checks that Monitor a CloudWatch Alarm Only)

If you create an Amazon Route 53 health check that monitors the status of a CloudWatch alarm and then you update the settings in the CloudWatch alarm, Amazon Route 53 doesn't automatically update the alarm settings in the health check. If you want the health check to start using the new alarm settings, you need to update the health check.

Note

To update a health check programmatically, you can use the UpdateHealthCheck API. Just specify the current values for AlarmIdentifier and Region, and Amazon Route 53 will get the latest settings from CloudWatch. For more information, see UpdateHealthCheck in the Amazon Route 53 API Reference.

To update a health check with new CloudWatch alarm settings

  1. Sign in to the AWS Management Console and open the Amazon Route 53 console at https://console.aws.amazon.com/route53/.

  2. In the navigation pane, choose Health Checks.

  3. Select the check box for the health check that you want to update.

  4. Choose Edit health check.

    A note explains that the CloudWatch alarm for the health check has changed. The Details field shows the new alarm settings.

  5. Choose Save.
