The report includes the following values:

**DistributionID**

**TimeBucket**  
The hour or the day that the data applies to, in Coordinated Universal Time (UTC).

**BytesUploaded**  
The number of bytes that viewers uploaded for the specified distribution during the time period.

**TotalErrorRatePct**  
The percentage of requests for which the HTTP status code was a `4xx` or `5xx` error for the specified distribution during the time period.

**4xxErrorRatePct**  
The percentage of requests for which the HTTP status code was a `4xx` error for the specified distribution during the time period.

**5xxErrorRatePct**  
The percentage of requests for which the HTTP status code was a `5xx` error for the specified distribution during the time period.

If you have [turned on additional metrics](viewing-cloudfront-metrics.md#monitoring-console.distributions-additional) for your distribution, then the report also includes the following additional values:

**OriginLatency**  
The total time spent, in milliseconds, from when CloudFront received a request to when it started providing a response to the network (not the viewer), for requests that were served from the origin, not the CloudFront cache. This is also known as *first byte latency*, or *time-to-first-byte*.

**CacheHitRate**  
The percentage of all cacheable requests for which CloudFront served the content from its cache. HTTP `POST` and `PUT` requests, and errors, are not considered cacheable requests.
