Zabbix is a powerful open-source monitoring platform, capable of monitoring anything and everything, with the right configuration. Zabbix's powerful Discovery capability is awesome, making it possible to automatically register hosts as they come online or monitor database servers without having to add individual databases and tables one by one. This repo contains everything you need to discover and monitor HAProxy frontends, backends and backend servers.
HAProxy is an awesome multi-purpose load-balancer.
HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for very high traffic web sites and powers quite a number of the world's most visited ones. Over the years it has become the de-facto standard opensource load balancer, is now shipped with most mainstream Linux distributions, and is often deployed by default in cloud platforms.

userparameter_haproxy.confinto/etc/zabbix/zabbix_agentd.d/directory, assuming you have Include set inzabbix_agend.conf, like so:
### Option: Include
# You may include individual files or all files in a directory in the configuration file.
# Installing Zabbix will create include directory in /usr/local/etc, unless modified during the compile time.
#
# Mandatory: no
# Default:
Include=/etc/zabbix/zabbix_agentd.d/
- Place
haproxy_discovery.shinto/usr/local/bin/directory and make sure it's executable (sudo chmod +x /usr/local/bin/haproxy_discovery.sh) - Import
haproxy_zbx_template.xmltemplate via Zabbix Web UI interface (provided byzabbix-frontend-phppackage) - Configure HAProxy control socket
- Configure HAProxy to listen on
/run/haproxy/info.sock - or set custom socket path in checks (set
{$HAPROXY_SOCK}template macro to your custom socket path) - or update
userparameter_haproxy.confandhaproxy_discovery.shwith your socket path
- Configure HAProxy to listen on
- Customize your HAProxy config file location via
{$HAPROXY_CONFIG}template macro, if necessary
# haproxy.conf snippet
# haproxy read-only non-admin socket
## (user level permissions are required, admin level will work as well, though not necessary)
global
stats socket /run/haproxy/info.sock mode 666 level user
- Verify on server with HAProxy installed:
anapsix@lb1:~$ sudo zabbix_agentd -t haproxy.list.discovery[FRONTEND]
haproxy.list.discovery[FRONTEND] [t|{"data":[{"{#FRONTEND_NAME}":"http-frontend"},{"{#FRONTEND_NAME}":"https-frontend"}]}]
anapsix@lb1:~$ sudo zabbix_agentd -t haproxy.list.discovery[BACKEND]
haproxy.list.discovery[BACKEND] [t|{"data":[{"{#BACKEND_NAME}":"www-backend"},{"{#BACKEND_NAME}":"api-backend"}]}]
anapsix@lb1:~$ sudo zabbix_agentd -t haproxy.list.discovery[SERVERS]
haproxy.list.discovery[SERVERS] [t|{"data":[{"{#BACKEND_NAME}":"www-backend","{#SERVER_NAME}":"www01"},{"{#BACKEND_NAME}":"www-backend","{#SERVER_NAME}":"www02"},{"{#BACKEND_NAME}":"www-backend","{#SERVER_NAME}":"www03"},{"{#BACKEND_NAME}":"api-backend","{#SERVER_NAME}":"api01"},{"{#BACKEND_NAME}":"api-backend","{#SERVER_NAME}":"api02"},{"{#BACKEND_NAME}":"api-backend","{#SERVER_NAME}":"api03"}]}]
- Add hosts with HAProxy installed to just imported Zabbix HAProxy template.
- Wait for discovery.. Frontend(s), Backend(s) and Server(s) should show up under Host Items.
An easy way to see all data is via Overview (make sure to pick right Group, one of the "HAProxy" applications and select Data as Type)
