# 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
