    # to have these messages end up in /var/log/haproxy.log you will
819a9f
    # need to:
819a9f
    #
819a9f
    # 1) configure syslog to accept network log events.  This is done
819a9f
    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
819a9f
    #    /etc/sysconfig/syslog
819a9f
    #
819a9f
    # 2) configure local2 events to go to the /var/log/haproxy.log
819a9f
    #   file. A line like the following can be added to
819a9f
    #   /etc/sysconfig/syslog
819a9f
    #

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