Logging Configuration

HAProxy Concepts - Logging

Configure HAProxy to Log into a File

Last time I tried this, it did not work:

Configure syslog to accept network log events. Add the '-r' option to the SYSLOGD_OPTIONS in /etc/sysconfig/rsyslog:

SYSLOGD_OPTIONS="-r"

Configure local2 events to go to the /var/log/haproxy.log file. Add the following line in /etc/rsyslog.conf:

local2.*  /var/log/haproxy.log
