# 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

haproxyログを/var/log/haproxy.logに送信するようにrsyslogを設定しましたが、haproxyサービスの開始ログと停止ログのみが表示され、haproxy呼び出しログは表示されません。
答え1
haproxyはデフォルトでrsyslogを使用しているので、次の設定が必要だと思います。
ファイルを作成/開き、vim /etc/rsyslog.d/haproxy-rsyslog.conf
次のコードを追加します。
$ModLoad imudp
$UDPServerRun 514
$UDPServerAddress 0.0.0.0
local0.* /var/log/haproxy.log
「rsyslog」サービスを再起動すると、「/var/log/haproxy.log」にファイルが生成されます。
