| 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 |
