#to have these messages end up in /var/log/haproxy.log you will

#need to:

#

#1) configure syslog to accept network log events.This is done

#byadding the '-r' option to the SYSLOGD_OPTIONS in

#/etc/sysconfig/syslog

#

#2) configure local2 events to go to the /var/log/haproxy.log

#file.A line like the following can be added to

#/etc/sysconfig/syslog

#

#local2.*/var/log/haproxy.log
