Здравствуйте.
Есть хост с HAProxy
который принимает входящий http/https трафик

и раскидывает на 2 backend
10.0.1.12
10.0.1.13
используется версия HAProxy 1.8

global
# to have these messages end up in /var/opt/rh/rh-haproxy18/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/opt/rh/rh-haproxy18/log/haproxy.log
# file. A line like the following can be added to
# /etc/sysconfig/syslog
#
# local2.* /var/opt/rh/rh-haproxy18/log/haproxy.log
#
log 127.0.0.1 local2
