# DEX Diagnostics

DEX Diagnostics is an AI-powered capability that helps IT professionals quickly understand processes, executables, faulting modules (DLLs), and Windows error codes associated with managed devices. When a supported diagnostic item is selected, Zia generates a concise summary explaining its purpose, category, severity where applicable, and relevance. This helps administrators identify unknown components, interpret diagnostic information, and make faster, more informed troubleshooting decisions during endpoint analysis.

## Use DEX Diagnostics

1. Navigate to **DEX > Insights**.
2. Open the required insight page.
3. Click **View** on a KPI or **View** on a table to open the detailed data view.
4. Click the required process name (EXE), or select a highlighted value under **Top Processes**, **Faulting Modules**, or **Error Codes**.
5. Review the diagnostic information in the Zia pop-up.
6. Use the information to decide whether the selected item requires further investigation or remediation.

## Considerations

- The available summary, category, and severity depend on the metadata available for the selected item.
- DEX Diagnostics provides explanatory context. It does not confirm the root cause or perform remediation.
- Review the generated information with the affected device data before applying configuration changes or troubleshooting steps.
