New Time Metric for CloudFront Logs

Amazon silently introduced a new time-taken property to the CloudFront access logs for web distributions last week.

The time-taken field shows the number of seconds between the time a CloudFront edge server receives a viewer’s request and the time that CloudFront writes the last byte of the response to the server’s output queue as measured on the server.

We have added support for this additional field which can be evaluated using the Total Time metric in Qloudstat.
