Check if perms are right chmod +x /var/lib/zabbix/haproxy/*.sh
Modify haproxy socket path in simple_haproxy_stats.sh

HAProxy requisites

HAProxy 1.6.x and socat are required. Autodiscovery feature uses "set server state" command through socket that appears in HAProxy 1.6.

It's necessary to be able to acces to haproxy socket.
You will have to add some configuration to haproxy config file (usually haproxy.cfg)

global
    stats socket /var/lib/haproxy/stats mode 666 level admin

Notice: mode 666 if zabbix user is running zabbix-agent.

Test

/var/lib/zabbix/haproxy/simple_haproxy_discovery.sh Should return a json with your fronts and servers.

/var/lib/zabbix/haproxy/simple_haproxy_stats.sh <backend_name> <server_name> hrsp_2xx Should return the number of 200 OK responses of your backend_name/server_name.

He made a very complete plugin but sometimes is hard to make it work.
