Apache Compatible HAProxy Log Formatting?

[Joel Krauska]

Has anyone worked out a way to get HAProxy to output logging in an 
Apache Combined Log Format?


Most log analysis tools out there already speak Apache log format and I 
was hoping to avoid writing a parser for what is essentially mostly the 
same information.


Anyone got a work around for this situation?

Best,

Joel

Hi Joel,

you can try option httplog clf instead of option httplog

 option httplog [ clf ]
   Enable logging of HTTP request, session state and timers
   May be used in sections :   defaults | frontend | listen | backend
  yes   |yes   |   yes  |   yes
   Arguments :
 clf   if the clf argument is added, then the output format
   will be the CLF format instead of HAProxy's default HTTP format. You
   can use this when you need to feed HAProxy's logs through a specific
   log analyser which only support the CLF format and which is not
   extensible.
 
 
 Be careful, HAproxy's CLF is Apache's common log format, not the
 combined log format that Joel originally asked for. The latter also
 logs the User-Agent and Referer headers.

 Ah yes.
 
 That's 95% though. I'll take it.
 
 Combined would be a great addition.

Hey, simply add header captures and you'll get it at a different position
though.

 Even better would be apache style custom format syntax.

No, it serves a different purpose. Some info that apache has are not in
haproxy and many of the info haproxy logs cannot be expressed with the
custom format.

Anyway, we've planned to do a big rework of the logs subsystem to make
them much more extensible.

Willy
