HAPROXY

HAPROXY

HAProxy is free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers. It is written in C and has a reputation for being fast and efficient

HAProxy by HTTP

Overview

For Zabbix version: 6.2 and higher
The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template HAProxy by HTTP collects metrics by polling HAProxy Stats Page with HTTP agent remotely.

Note that this solution supports https and redirects.

This template was tested on:

  • HAProxy, version 1.8

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{HOST.CONN}, {$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

If you want to use authentication, set the username and password in the "stats auth" option of the configuration file and in the macros {$HAPROXY.USERNAME},{$HAPROXY.PASSWORD}.

Zabbix configuration

No specific Zabbix configuration is required.

HAProxy frontend {#PXNAME}: Session utilization is high

Alerting on this metric is essential to ensure your server has sufficient capacity to handle all concurrent sessions. Unlike requests, upon reaching the session limit HAProxy will deny additional clients until resource consumption drops. Furthermore, if you find your session usage percentage to be hovering above 80%, it could be time to either modify HAProxy's configuration to allow more sessions, or migrate your HAProxy server to a bigger box.
