The HTTP Log Format tracks bytes_read, which appears to be the number of bytes in the HTTP response send from the backend to the requesting client.
https://code.google.com/p/haproxy-docs/wiki/HTTPLogFormat I feel also that bytes_sent may be an interesting field to track. For example: An Image upload site may care a lot more about image uploads to their servers than downloads. (esp for an upload backend pool) Checking the ratio of bytes_read vs bytes_sent also provides interesting insight in to how an application is performing. Is there anyway I can lobby to get bytes_sent added to future revisions of the HTTP Log format? Is there any other method to collect this info? The stats page is already collecting Bytes in and Bytes out, but I'm missing it in the log format, so I can't look at it on a per-request level. Thanks, Joel
