# health This module enables a simple health check. By default it will listen on port 8080. Restarting CoreDNS will stop the health checking. This is a bug. Also [this upstream Caddy bug](https://github.com/mholt/caddy/issues/675). ## Syntax ~~~ health ~~~ Optionally takes an address; the default is `:8080`. The health path is fixed to `/health`. It will just return "OK" when CoreDNS is healthy. This middleware only needs to be enabled once. ## Examples ~~~ health localhost:8091 ~~~
