# health
|
|
|
|
This module enables a simple health check.
|
|
|
|
By default it will listen on port 9180.
|
|
|
|
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
|

|
|
|
|
It 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.
