When monitoring CloudFront, the CloudWatch monitoring service allows us to get an idea of the performance of our CloudFront distribution and the consumption of our CloudFront resources by our distribution. The CloudFront dashboard also includes a nice feature that allows us to overview the error rates, as seen in the top-right corner of the following screenshot:
As this demo distribution seems to be error prone, we can drill down into the error metrics by clicking on the Metrics selection from the menu on the left and then view the detailed CloudFront metrics.
In this example, we have chosen just the requests and the 400 error rate to try and determine whether there is any correlation between the requests and the relatively high number of errors:
As you can see, CloudWatch can be a valuable tool for analyzing different types of metrics that are reported...
