Looks rather strange. Could you try stracing syslogd and haproxy upon startup to check 1) if haproxy sends a log, and 2) if syslogd receives it ?

If you see syslogd receives the logs but does not write them, check that your syslogd is currently running with the above config (maybe a kill -HUP was forgotten after tweaking the config).

If haproxy does not emit anything, then try changing the address, or forcing the port (127.0.0.1:514), then try removing the level filter ("debug") and try changing the facility ("syslog") to something else (eg: local0).

You should see the lines indicating that haproxy has started.

Oh, BTW, I notice that you don't have any "log" statement in your listen section. You should add "log global", otherwise you will only get the process management logs ("starting" and "stopping"). Maybe you did not notice those and are just seeking for traffic logs, reason why you thought logging did not work ?

BTW, if your upstream client(s) do keep-alive, you will only get the first request in the logs. In this case, you'll have to add "option httpclose" in the listen section.

Hoping this helps,
