A health check can be configured in order to remove a backend from LB rotation as long as it keeps returning HTTP status codes other than `2xx` or `3xx` to HTTP GET requests periodically carried out by Traefik. A health check can be configured in order to remove a backend from LB rotation as long as it keeps returning HTTP status codes other than `2xx` or `3xx` to HTTP GET requests periodically carried out by Traefik.
The check is defined by a path appended to the backend URL and an interval (given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)) specifying how often the health check should be executed (the default being 30 seconds). The check is defined by a path appended to the backend URL and an interval specifying how often the health check should be executed (the default being 30 seconds.)
Each backend must respond to the health check within 5 seconds. Each backend must respond to the health check within a timeout duration (the default being 5 seconds.)
Interval and timeout are to be given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration).
The interval must be greater than the timeout. If configuration doesn't reflect this, the interval will be set to timeout + 1 second.
By default, the port of the backend server is used, however, this may be overridden. By default, the port of the backend server is used, however, this may be overridden.
