# Using Digital End-user Experience Self-service

With Digital End-user Experience Self-service, you can monitor device performance using the **Device health check** feature available in Desktop Assistant and Employee Center, or conversationally through the ServiceNow Otto for ITSM Virtual Agent.

You can access Device health check from the following sources:

-   Employee Center. See [Check device health using Employee Center](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/digital-end-user-experience-dex/check-your-device-s-using-employee-center.md).
-   Desktop Assistant. See [Check device health using Desktop Assistant](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/digital-end-user-experience-dex/check-your-device-s-health-using-desktop-assistant.md).
-   Now Assist for ITSM Virtual Agent. See [Check device health using ServiceNow Otto for ITSM Virtual Agent](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/digital-end-user-experience-dex/check-your-device-s-health-using-now-assist-for-itsm.md).

You might be unable to access the Device health check widget or page due to the following reasons:

-   The device isn't assigned: DEX monitored devices aren’t assigned to you. 
-   The device is offline: The device list drop-down is inactive and you see a message that the device is currently offline.
-   The device is online but no recent data is available: You see a message notifying you that Device health check is unavailable and are prompted to retry later or open an IT ticket.
