Health-Check Servers

Configure health-check servers for the FortiGate unit to verify that real servers are able respond to network connection attempts. If a real server responds to connection attempts, the load balancer continues to send sessions to it. If a real server stops responding to connection attempts, the load balancer assumes that the server is down and does not send sessions to it. The health-check servers configuration determines how the load balancer tests the real servers. You can use a single health-check servers for multiple load balancing configurations.
