Create alarms for metrics

In the CloudFront console, you can set alarms to notify you by Amazon Simple Notification Service (Amazon SNS) based on specific CloudFront metrics.

To create alarms for metrics

  1. Sign in to the Amazon Web Services Management Console and open the CloudFront console at https://console.amazonaws.cn/cloudfront/v4/home.

  2. In the navigation pane, choose Alarms.

  3. Choose Create alarm.

  4. For Details, specify the following:

    1. Alarm name – A name for the alarm.

    2. Distribution – The CloudFront distribution that you're creating the alarm for.

  5. For Condition, specify the following:

    1. Metric – The metric that you're creating the alarm for.

    2. "IF" <condition> – The threshold when CloudWatch should trigger an alarm and send a notification to the Amazon SNS topic. For example, to receive a notification when the 5xx error rate exceeds 1%, specify the following:

      5xx error rate > 1

    3. "FOR" consecutive periods – The period of time that the condition must be met before triggering an alarm. When you choose a value, aim for an appropriate balance between a value that doesn't alarm for temporary problems, but will alarm for sustained or real problems.

    4. (Optional) Notify – The Amazon SNS topic to send notification to if this metric triggers an alarm.

  6. Choose Create alarm.

Notes

  • When you enter the values for the condition, use whole numbers without punctuation. For example, to specify one thousand, enter 1000.

  • For 4xx, 5xx, and total error rates, the value that you specify is a percentage.

  • For requests, bytes downloaded, and bytes uploaded, the value that you specify is units. For example, 1073742000 bytes.
