 Prometheus is a monitoring and alerting system. More and more people use it to
 monitor their environment (this is written February 2019). It collects metrics
 from monitored targets by scraping metrics HTTP endpoints on these targets. For

 (https://github.com/prometheus/haproxy_exporter). But it requires an extra
 software to deploy and monitor. PROMEX, on its side, is a built-in Prometheus
 exporter for HAProxy. It was developed as a service and is directly available in
 HAProxy, like the stats applet.

 must loop on all proxies for each metric. Same for the servers. Thus, it will
