Dear Jarno,

Thanks for your message.

Ok, my /haproxy -vv/ output is as follows:

The setting for the logging was done in the /default /section as:

   log-format %Ci:%Cp\ [%t]\ %ft\ %b/%s\ %Tq/%Tw/%Tc/%Tr/%Tt\ %st\ %B\ %cc\ %cs\ %tsc\ %ac/%fc/%bc/%sc/%rc\ %sq/%bq\ %hr\ %hs\ %[capture.req.hdr(0)]\ %{+Q}r
        option log-separate-errors
        option log-health-checks

and in the /http /and /https /section the body parameter capturing is activated as:

    # enable HTTP body logging
        option http-buffer-request
        declare capture request len 4
        http-request capture req.body_param(customerId) id 0

As my haproxy version differs from yours I'm unsure where I might made a configuration error.

Thanks for your help,
best
Simon

Hi,

We use the req.body_param([<name>]) setting to retrieve body
parameter from the incoming HTTP queries and place them into the
logs.

Unfortunately this only works with HTTP POST requests. In our case
we need to extract the parameter from PUT requests as well.

Would it be an option to use req.body_param([<name>]) on any HTTP
method type instead of restricting it to HTTP POST?
Can you share your haproxy -vv and the logging config ?

I just tested with haproxy-ss-20180507 and this minimal test
seems to get req.body_param(log) to stick table on both POST/PUT requests
(tested w/curl -X PUT|POST):
...
frontend test
         option  http-buffer-request
         bind ipv4@127.0.0.1:8080
         http-request track-sc2 req.body_param(log),lower table test_be if 
METH_POST || METH_PUT

         default_backend test_be

backend test_be
         stick-table type string len 48 size 64 expire 240s store http_req_cnt
         server wp2 some.ip.add.ress:80 id 2
...

curl -X PUT -d'log=user1' http://127.0.0.1:8080/
curl -X POST -d'log=user2' http://127.0.0.1:8080/
