Grafana dashboard: HAproxy Frontend | HAproxy
Description: HAproxy Frontends

This dashboard displays the detailed number of requests and their split by HTTP codes along aggregated throughput for the haproxy frontends.

It requires that you gather haproxy metrics using the haproxy_exporter from prometheus [link](https://github.com/prometheus/haproxy_exporter "here")

Example prometheus configuration:
```
  - job_name: 'loadbalancer1'
    static_configs:
      - targets: ['172.18.0.108:9101']
        labels:
          alias: loadbalancer1
```

You need to have the stats option configured in your global section of haproxy.cfg, example:

```
global
	log /dev/log	local0
	log /dev/log	local1 notice
	user haproxy
	group haproxy
	maxconn  16000
	stats  socket /var/lib/haproxy/stats level admin
	tune.bufsize  32768
	tune.maxrewrite  1024
	tune.ssl.default-dh-param 2048
	daemon
```
You can start the exporter to listen on the unix socket:
```
haproxy_exporter -haproxy.scrape-uri unix:/var/lib/haproxy/stats
```
