Partial Transfer Metric

Qloudstat supports a partial transfer metric for S3 and Rackspace Cloudfiles/Akamai endpoints. We determine partial transfers as follows:

  • S3. Log files for S3 include the actual transmitted number of bytes. If it differs from the content length the request is counted as partial.
  • Rackspace Cloudfiles. Partial transfer counts are based on a feature by Akamai CDN that marks transfers interrupted by the client with a 000 status code in the log file.

These are also taken into account when counting bandwidth and transfer cost metrics.
