---


After connecting your NGINX instances to NGINX One, you can monitor their performance and health. The NGINX One dashboard is designed for this purpose, offering an easy-to-use interface.

### Log in to NGINX One

1. Log in to [F5 Distributed Console](https://www.f5.com/cloud/products/distributed-cloud-console).
1. Select **NGINX One > Visit Service**.

Navigating the dashboard:

- **Drill down into specifics**: For in-depth information on a specific metric, like expiring certificates, click on the relevant link in the metric's card to go to a detailed overview page.
- **Refine metric timeframe**: Metrics show the last hour's data by default. To view data from a different period, select the time interval you want from the drop-down menu.
