about haproxy's logging not working on OpenBSD ...

[zje.net.cn]

Hi, I have install the haproxy ver1.5.14 on OpenBSD 5.8 ,
but i can not find the logs of haproxy anywhere even try to make any 
cofigurations for it with syslogd,
i thik the logging must not be working with any reasons, then i was wondering 
how to do.
Sorry,perhaps it is not a bug of haproxy or OpenBSD, but i realy want to know 
how to let haproxy's logging working??
Thinks for your help!
