Load balancing FMS servers using LVS (DR mode)
How do we configure LVS (or any load balancer for that matter) to detect when there has been a failure of a particular real server?
Answer by Jean--
It is possible to load balance using LVS, we could do an HTTP health monitor against FMS since it supports tunneling over HTTP. We can also probably hit the admin service port of the FMS server, which has a REST like interface and use some metrics like the number of streams or number of application instances. keep alived or something similar should work for the actual interface for putting servers in an out of rotation for local server load balancing. People generally know who use LVS write their own custom health check layer.
