# to have these messages end up in /var/log/haproxy.log you will
|
|
|
763875 |
# need to:
|
|
|
763875 |
#
|
|
|
763875 |
# 1) configure syslog to accept network log events. This is done
|
|
|
763875 |
# by adding the '-r' option to the SYSLOGD_OPTIONS in
|
|
|
763875 |
# /etc/sysconfig/syslog
|
|
|
763875 |
#
|
|
|
763875 |
# 2) configure local2 events to go to the /var/log/haproxy.log
|
|
|
763875 |
# file. A line like the following can be added to
|
|
|
763875 |
# /etc/sysconfig/syslog
|
|
