### Usage for Caddy HTTP server
If you want to monitor Caddy, you need to use Caddy with its Prometheus plugin:
* Download Caddy+Prometheus plugin [here](https://caddyserver.com/download/linux/amd64?plugins=http.prometheus)
* Add the `prometheus` directive in your `CaddyFile`
* Restart Caddy
* Configure Telegraf to fetch metrics on it:
```
[[inputs.prometheus]]
# ## An array of urls to scrape metrics from.
urls = ["http://localhost:9180/metrics"]
```
> This is the default URL where Caddy Prometheus plugin will send data.
> For more details, please read the [Caddy Prometheus documentation](https://github.com/miekg/caddy-prometheus/blob/master/README.md).
