Integrating HAProxy

Before you configure the HAProxy integration, you must have the IP Address of the USM Appliance Sensor.

To configure HAProxy to send Syslog messages to USM Appliance

HAProxy supports five different log formats, with several fields common among these formats. The HTTP format provides the recommended and most advanced logging features for HTTP proxies, and it provides the same information as the TCP format, along with some additional HTTP-specific field information. To enable the HTTP format option, set "option httplog" as a "frontend" configuration section parameter.

To send logs to USM Appliance, edit the HAProxy server configuration file (/etc/haproxy/haproxy.cfg) to include the following lines:


log <<USM-Appliance-Sensor-IP-Address>>:514 <facility>

where <facility> must be one of the 24 standard syslog facilities options:

  • kern
  • user
  • mail
  • daemon
  • auth
  • syslog
  • lpr
  • news
  • uucp
  • cron
  • auth2
  • ftp

  • audit
  • alert
  • cron2
  • local0
