 ## Multi-Target Support (BETA)
 **This Feature is in beta and may require changes in future releases. Feedback is welcome.**
 
-This exporter supports the [multi-target pattern](https://prometheus.io/docs/guides/multi-target-exporter/). This allows running a single instance of this exporter for multiple postgres targets. Using the milti-target funcationality of this exporter is **optional**. To use the multi-target functionality, send an http request to the endpoint `/probe?target=foo:5432` where target is set to the DSN of the postgres instance to scrape metrics from.

 To avoid putting sensitive information like username and password in the URL, preconfigured auth modules are supported via the [auth_modules](#auth_modules) section of the config file. auth_modules for DSNs can be used with the `/probe` endpoint by specifying the `?auth_module=foo` http parameter.
