How to configure Amazon CloudFront Streaming log with CloudBerry Explorer

Note: this post applies to CloudBerry Explorer 2.1 and later.

Amazon CloudFront has been offering access logs for HTTP distributions for quite some time. Now this feature is extended to work with streaming distributions as well. Amazon team has designed CloudFront access logs for streaming to work in a very similar fashion to the existing access logs for HTTP distributions.

Access logs for streaming will, however, have a different record layout that reflects the different nature of streaming delivery. Each record in a streaming access log will represent a distinct playback event – connect, play, pause, stop, disconnect and so on. So, each time one of your viewers watches a video, you’ll see multiple records in your access logs.

CloudBerry Explorer has been supporting Amazon S3 server access logging and CloudFront access logging from a long time. Following the recent announcement CloudBerry Explorer added a support for enabling CloudFront logging and generating simple reports.

To turn this option on simply go to Streaming Distribution properties, Logging tab and choose Use logging option. Select the bucket and prefix where you want the log files to be written.

Enabling logging is only half of the deal as you can imagine and once log files come to the bucket you may want to analyze them. Select the bucket with configured as a streaming distribution and with streaming log enabled. Go to the logging tool bar and choose View Streaming Access Log in the drop down menu.

CloudBerry Explorer comes with a few basic reports that help you get a feel of the information stored in your log files. Here is an example of the log file in the tabular format.

Another important feature related to log files is that CloudBerry Explorer PRO improves the performance of the log files by allowing for maintaining a local cache. You can notice a significant performance improvement when working with built-in CloudBerry Explorer reports and charts.
