  13     # to have these messages end up in /var/log/haproxy.log you will
  14     # need to:
  15     #
  16     # 1) configure syslog to accept network log events.  This is done
  17     #    by adding the '-r' option to the SYSLOGD_OPTIONS in
  18     #    /etc/sysconfig/syslog
  19     #
  20     # 2) configure local2 events to go to the /var/log/haproxy.log
  21     #   file. A line like the following can be added to
  22     #   /etc/sysconfig/syslog
  23     #
  24     #    local2.*                       /var/log/haproxy.log
