        ## Description
        
        frontend stats bind *:8880 http-request use-service prometheus-exporter if { path /metrics } stats enable stats uri /stats stats refresh 10s
        
        ## Overview
        
        Permit getting stats via prometheus exporter (since haproxy 2.0)
        
        
        First, configure your haproxy to expose frontend stats page like this :
        
        
        frontend stats  
         bind *:8880  
         http-request use-service prometheus-exporter if { path /metrics }  
         stats enable  
         stats uri /stats  
         stats refresh 10s
        
        
        Then, check the item haproxy.prometheus.allmetrics URL.
        
        
        Discovery for frontends, backends, servers.
        
        
        * Check if <50% of backend are down (not up, like DRAIN, NOLB, etc )on a frontend.
        * Check if connections are >90/95% of the limit on frontend
        * Check status of frontend and backend.
