    stats realm Haproxy\ Statistics
#automatic redirect for http to https connections

       redirect location https://<insert_fqdn_address_here>
#front settings in this case we bind to all addresses on system or specify an interface
    frontend vrops_frontend_secure
       bind <web dedicated ip>:443 
       mode tcp 
       option tcplog 
       default_backend vrops_backend_secure
#backend configuration of receiving servers containing tcp-checks health checks and hashing

    tcp-check connect port 443 ssl
    tcp-check send GET\ /suite-api/api/deployment/node/status?services=api&services=adminui&services=ui\ HTTP/1.0\r\n\r\n
## For older versions of vROPS from 6.6.1 to 7.5 please use the following “tcp-check”
# tcp-check send GET\ /suite-api/api/deployment/node/status\ HTTP/1.0\r\n\r\n
tcp-check expect rstring ONLINE
server node1 <Insert node1 ip address here>:443 check inter 15s check-ssl maxconn 140 fall 3 rise 3
server node2 <Insert node2 ip address here>:443 check inter 15s check-ssl maxconn 140 fall 3 rise 3
server node3 <Insert node3 ip address here>:443 check inter 15s check-ssl maxconn 140 fall 3 rise 3
server node4 <Insert node4 ip address here>:443 check inter 15s check-ssl maxconn 140 fall 3 rise 3

Note:

Please make sure to use proper tcp-check call in above instruction. Starting from vROps 8.0 status API enhanced to track separate services status. Old “tcp-check” call provided above in comments.
