Redirect traffic depending nodes active/passive

not sure if i understand question correctly.

you are saying that service is on port 5555 which is always up but active node is determined by port 7777, aren't you? if so, can we make health monitor to port 7777?

e.g.

[root@ve10:Active] config  b pool Pool_DATA_PROTECTOR_ORIB_APP_PRD list
pool Pool_DATA_PROTECTOR_ORIB_APP_PRD {
   monitor all myhttp
   members {
      10.193.30.52:5555 {}
      10.193.30.56:5555 {}
   }
}

[root@ve10:Active] config  b monitor myhttp list
monitor myhttp {
   defaults from http
   dest *:7777
}
