- If you haven't done it already, please enable access to your AWS resources either by creating Site24x7 as an IAM user or by creating a cross-account IAM role between your AWS account and Site24x7's AWS account. Learn more.
- Next, in the Integrate AWS Account page, please ensure the CloudFront check box is selected in the Services to be discovered field. Learn more.
Policies and permissions
Please make sure the following read level actions are present in the policy statement assigned to the Site24x7 IAM entity. Learn more.
- "cloudfront:GetDistribution",
- "cloudfront:ListPublicKeys",
- "cloudfront:ListTagsForResource",
- "cloudfront:ListInvalidations",
- "cloudfront:ListDistributions",
- "cloudfront:GetDistributionConfig"
Polling frequency
Site24x7 queries CloudWatch and various service level APIs as per the poll frequency set (1 minute to a day), to collect performance metrics and metadata for your CloudFront distributions.
To view metrics:
- Log in to the Site24x7 console, click on AWS > Monitored AWS account and choose CloudFront from the drop down.
- From the list of monitored distributions, choose the distribution for which you want to access metrics for.
- The various graphs applicable for your Amazon CloudFront Distribution are displayed in the Summary tab.

| Total error rate | Measures the percentage of total request that returned a 4xx or a 5xx error code | Average | Percent |
| 4xx error rate | Measures the percentage of requests that return a HTTP status code 4xx | Average | Percent |
| 5xx error rate | Measures the percentage of requests that return a HTTP status code 5xx | Average | Percent |

The following config data are collected:
| Attribute | Description |
|---|---|
| Distribution ID | Shows the identifier for the distribution |
| Domain name | Shows the domain name that corresponds to the distribution |

| Last modified time | Displays the date and time the distribution was last modified. |
| Status | Displays the current status of the distribution. |
| State | Shows the distribution state – enabled or disabled. |
| Price class | Displays the price class associated with the distribution. |

You can collect your CloudFront logs for monitoring with the Site24x7 AppLogs agent. Learn more.
Support for Lambda@Edge
The Lambda@Edge error metrics can be viewed if you have Lambda@Edge in CloudFront. Plus, you can monitor the metrics available in the regional edge cache levels supported by AWS Lambda@Edge.
| Attribute | Description | Statistics | Data type |
|---|---|---|---|
| Execution Errors | Execution errors are returned when CloudFront doesn’t get a response after triggering a Lambda function. | Average | Count |
| Invalid Function Responses | When the response contains invalid headers or fields, an invalid function response error is displayed. | Average | Count |
| Throttles | The Lambda service throttles executions in each Region and returns an error if your CloudFront distribution tries to run a Lambda function when you're at the limit. | Average | Count |
Lambda@Edge errors
Various errors at CloudFront regional edge cache levels are provided to help you understand the faults in Lambda@Edge. You can view details like the region name, the associated AWS region, execution errors, and more. This section lets you configure the thresholds for each parameter in a particular region.
Lambda@Edge functions
The different Lambda@Edge functions associated with a CloudFront monitor are displayed here for each resource with details like Resource Name and Resource Type for a custom duration you choose. You can view status and set alerts for the monitored functions.
