Amazon CloudFront is a web service that speeds up the distribution of static and dynamic web content
(such as .html, .css, .js, and image files).
CloudFront delivers content through a worldwide network of data centers called edge locations.
For example, when a user requests content that you’re serving with CloudFront, the user is routed to the edge location that provides the lowest latency (time delay). Edge locations help deliver content with the best possible performance.
Use the AWS public cloud integration to discover and collect metrics against the AWS service.

| aws_cloudfront_5xxErrorRate Percentage of all requests for which the HTTP status code is 5xx. | 5xxErrorRate | Count | Average |
| cloud.instance.state Cloud front distribution status state metric | Status/State | n/a | n/a |
| aws_cloudfront_401ErrorRate Percentage of all viewer requests for which the response HTTP status code is 401. | 401ErrorRate | Percent | Average |
| aws_cloudfront_403ErrorRate Percentage of all viewer requests for which the response HTTP status code is 403. | 403ErrorRate | Percent | Average |

| aws_cloudfront_OriginLatency Total time spent, in milliseconds, from when CloudFront receives a request to when it starts providing a response to the network (not the viewer), for requests that are served from the origin, not the CloudFront cache. | OriginLatency | Milliseconds | Average |
