# Overview
## Viewing options
{% hint style="warning" %}
Only machines with the **Xopero ONE** agent installed are visible in the **Devices** tab.

#### In the **Devices** tab, devices can be displayed in two modes:
1. **Device view** — presents each device separately with detailed information about its last backups.
2. **List view** — optimized for managing a large number of devices; displays all devices in a table. In list view, you can configure column visibility, adjust the number of items per page, and view details such as group, IP address, description, agent version, operating system, and the time of the last successful backup.
