# Metrics

This module enables prometheus metrics for Caddy.

## Use

In your `Caddyfile`:

~~~

prometheus

~~~

For each virtual host that you want to see metrics for.

These are the (optional) parameters that can be used:

  - **use_caddy_addr** - causes metrics to be exposed at the same address:port as Caddy itself. This can not be specified at the same time as **address**.

  - **address** - the address where the metrics are exposed, the default is `localhost:9180`

  - **path** - the path to serve collected metrics from, the default is `/metrics`

  - **hostname** - the `host` parameter that can be found in the exported metrics, this defaults to the label specified for the server block

  - **label** - Custom label to add on all metrics.

    This directive can be used multiple times.  

    You should specify a label name and a value.  

    The value is a [placeholder](https://caddyserver.com/docs/placeholders) and can be used to extract value from response header for instance.  

    Usage: `label route_name {
