Question: How to get frontend stats by host header?

[dsouzajude]

Hi, i'm looking for a way to monitor frontends by host header in HAProxy config where we route by host header. For example, consider the following config:

frontend http-in
    bind *:80
    log /dev/log    len 65535 local1 info
    capture request header User-Agent len 30
    capture request header X-Request-ID len 36
    capture request header Host len 32

    # Frontend rules for host header routing
    use_backend user if { hdr(Host) -i user user.example.com  }
    use_backend login if { hdr(Host) -i login login.example.com }


backend user
    mode http
    server-template user 10 _user._tcp.service.consul resolvers consul resolve-prefer ipv4 check

backend login
    mode http
    server-template login 10 _login._tcp.service.consul resolvers consul resolve-prefer ipv4 check

Is there a way to get stats of all frontends, for example in particular haproxy.frontend.response.4xx by header:Host?
