Not sure about LUA exactly but HAProxy supports external health check scripts written in whatever language is available on the system so usually BASH/Perl/Python/Whatever.

https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#external-check

HAProxy passes some variables to be used by your script:

$1= VIP
$2= VIP_Port
$3= RIP
$4= RIP_Port

So you can use this info in your script.
