        # 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
        #    by adding 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
