Logging entire POST body with HAProxy?
Apparently since version 1.6.0 (October 2015) you can now. There is a new directive:
That you include in the front-end or back-end to give HAProxy access to the body. And you use req.body to access it. Here is a summary of the config I used:
global log 127.0.0.1 local0 debug maxconn 2048 ulimit-n 8012 # ... defaults mode http option httplog log-format frontend:%f/%H/%fi:%fp\ GMT:%T\ body:%[capture.req.hdr(0)]\ request:%r option dontlognull # ... frontend www-http log global option http-buffer-request # id=0 to store body for logging declare capture request len 40000 bind 220.127.116.11:8007 http-request capture req.body id 0 default_backend www-backend backend www-backend mode http option forwardfor # ...
Haproxy does not have a facility to log POST content or HTTP bodies.
Use Wireshark instead.
