The charts show your usage from each CloudFront region at daily or hourly granularity, going back up to 60 days, and they also include totals, average, and peak usage during the time interval selected.
These charts include: Number of HTTP/S Requests, Data Transferred over HTTP/S, Data Transferred from CloudFront Edge Locations to Your Users, and Data Transferred from CloudFront to Your Origin.

Amazon CloudFront monitoring & alarms via Amazon CloudWatch
Monitor, Alarm and Receive Notifications in Near Real-Time
You can monitor, alarm and receive notifications on the operational performance of your Amazon CloudFront distributions within a few minutes of viewer requests using Amazon CloudWatch, giving you more visibility into the overall health of your web application. CloudFront automatically publishes six operational metrics, each at 1-minute granularity, into Amazon CloudWatch. You can then use CloudWatch to set alarms on any abnormal patterns in your CloudFront traffic.
These metrics include: Requests, Bytes Downloaded, Bytes Uploaded, 4xx Error Rate, 5xx Error Rate and Total Error Rate. These are automatically provided to all CloudFront customers at no additional costs. Alarming is billed at standard CloudWatch rates.

Amazon CloudFront Access Logs
Enable CloudFront Logs to Learn More About Your Traffic
Cloudfront generates logs that provide detailed information about every request it receives and responds to. These logs are effectively equivalent to Web Server logs and are delivered in the same W3C format, but also contain additional CloudFront specific data. CloudFront logs can be very useful for exploring performance and usage trends and in isolating potential errors or configuration optimizations.
CloudFront provides two ways to log the requests that are delivered from your distributions: Standard logs and Real-time logs.
CloudFront standard logs are delivered to the Amazon S3 bucket of your choice (log records are delivered within minutes of a viewer request). When enabled, CloudFront will automatically publish detailed log information in a W3C extended format into an Amazon S3 bucket that you specify. Access logs contain detailed information about each request for your content, including the object requested, the date and time of the request, the edge location serving the request, the client IP address, the referrer, the user agent, the cookie header, and the result type (for example, cache hit, or miss, or error). CloudFront doesn’t charge for standard logs, though you incur Amazon S3 charges for storing and accessing the log files.
CloudFront real-time logs are delivered to the data stream of your choice in Amazon Kinesis Data Streams (log records are delivered within seconds of a viewer request). You can choose the sampling rate for your real-time logs—that is, the percentage of requests for which you want to receive real-time log records. You can also choose the specific fields that you want to receive in the log records. CloudFront real-time logs contain all the same data-points as the standard logs and also contain certain additional information about each request, such as viewer request headers and country code, in a W3C extended format. CloudFront charges for real-time logs, in addition to the charges you incur for using Kinesis Data Streams.
As part of the AWS Free Usage Tier, you can get started with Amazon CloudFront for free. Upon sign-up, new AWS customers receive 50 GB Data Transfer Out and 2,000,000 HTTP and HTTPS Requests each month for one year.
