# 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
#
#log 127.0.0.1 local2

Server running RHEL7 and it has selinux enforcing. I have followed all the steps in this link to setup rsyslog for haproxy which selinux enforce. But only logs shows is haproxy service start/stop logs, it doesn't show traffic logs.

Answer 1

Recently I have installed several haproxy services, Centos 6 and 5, I guess.
Config haproxy.cfg contains:
global
log 127.0.0.1 local2 info
Also, I have created a new file in /etc/rsyslog.d/haproxy.conf (I guess it does the job)
# Collect log with UDP
$ModLoad imudp
$UDPServerAddress 127.0.0.1
$UDPServerRun 514
# Creating separate log files based on the severity
local2.* /var/log/haproxy.log
After restarting rsyslog daemon, haproxy started writing to log.
P.S. After tests I have added as defaults to stop unnecessary info
option dontlog-normal
