Re: bytes_sent?

2013-05-15 Thread haproxy 
This is already present in haproxy 1.5.
1.5 has a `log-format` parameter which lets you specify a custom format.
The format has a `%U` parameter which is the number of bytes sent by the
client.

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?


You should look at custom log format
http://cbonte.github.io/haproxy-dconv/configuration-1.5.html#8.2.4

%B  bytes_read (from server to client)
or
%U  bytes_uploaded (from client to server)

I think that this option is only available in 1.5dev

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
