HAProxy one port down failover all ports

Question

I am trying to implement HAProxy for auto-failover for several ports. Like to have the capability to auto-failover all ports, such as 389, 443, and 8443 if any one of these ports is down.

Looks to me the following configuration only auto-failover on a port not all ports.

mode tcp
server s1 10.10.10.1:389 check inter 1s fail 3 rise 3
server s2 10.10.10.2:389 check backup

Thanks,

Write a simple script that for a given server checks all three ports and which will return a non-zero error condition when either one or more port/service fails.

Configure and use that script as an external-check command </path/to/scriptname> for all your services instead of the native checks.
