Health Monitor

[Gajji]

Health monitor has TCP

same server(10.25.26.23) has multiple port (80,443,88 , 666) has backend

what should be the monitor for it...

if i apply tcp_80, tcp_443 , tcp_88 and tcp_666.... when of the port goes down it will mark all as down.

"what should be the monitor for it", this depends on your requirements, but in the pool configuration under advanced settings you can specify what is the number of monitors that should be up for the member to be marked up. The setting entry is called "Availability requirement" and you can tell the system to either require all the monitors to be up, or at least a number you specify. Default is all so this may be the cause of your members being marked down

If we specify some number and based on that only backend should be marked as down..

so let say if one only one member in LB goes down , LB will still send traffic to backend and user might complain that there connection isn't working.
