_lb_health_check_oss.html.md.erb

Cloud Foundry uses the following properties:

`router.drain_wait`: Specifies, in seconds, the `unhealthy` threshold that determines when the Gorouter stops accepting connections and
the process gracefully stops. During this period, the Gorouter continues to serve HTTP requests and the health check endpoint returns `503` errors.

`router.load\_balancer\_healthy\_threshold`: Specifies the amount of time, in seconds, that the load balancer waits until it declares the
Gorouter instance `started`. This enables the load balancer time to register the instance as `healthy`.
