Advanced configuration options provide additional customization capabilities beyond standard settings. These options allow you to fine-tune system behavior and optimize performance for specific organizational
requirements.
* **[Convert an application source to DEX](https://servicenow-prod.fluidtopics.net/5ZYgY475zktJvIKeKr7KTw)**   
  Convert a Visibility Content application to DEX monitoring. After conversion, the application is managed in the Application and Device Health system.
* **[Map a device user to a ServiceNow DEX user](https://servicenow-prod.fluidtopics.net/2cIIfB2vqGf8ufpyoPp8pA)**   
  Complete this procedure to map a device user to a DEX user so you can notify the user about any of the device metrics breaching a predetermined threshold.
* **[Device location determination](https://servicenow-prod.fluidtopics.net/WwxY7RH0Fkyi0Uh9EMp05g)**   
  Identify and determine the number of impacted devices based on the location by defining a custom logic.
* **[Configure ACC to use a proxy for all traffic](https://servicenow-prod.fluidtopics.net/45_m6kWmq3dDWE36qdmoHg)**   
  Configure the Agent Client Collector (ACC) to use a proxy for all traffic by setting environment variables. Using a proxy helps you enhance security, monitor and control internet usage, improve performance through caching, protect privacy, and enforce compliance with your organization's policies.
* **[Switch ACC from one instance to another](https://servicenow-prod.fluidtopics.net/JXI8m~zAMrUVGeSYBUBTMQ)**   
  Switch Agent Client Collector (ACC) to a different instance.
* **[Configure MID-less Agent Client Collector using a single-line command](https://servicenow-prod.fluidtopics.net/BxAGTslVHdjwJ~sJfeYXQA)**   
  Use a single-line command to set up a MID-less Agent Client Collector. You can also use the single-line command to migrate agents configured with a MID Server to have a MID-less configuration.
* **[Convert MID-based ACC to MID-less](https://servicenow-prod.fluidtopics.net/jEBFIYcEu3kHF0BhR7pe3A)**   
  Convert MID-based Agent Client Collector (ACC) to MID-less ACC by adjusting the configuration in acc.yml, decoupling from a specific MID to enhance flexibility and adaptability.
* **[Sudo banner validation](https://servicenow-prod.fluidtopics.net/M6DyLeRy8jmHZmO7Iz0J8A)**   
  Sudo banner validation flags missing sudo permissions on managed devices so you know when the DEX agent's capabilities are limited.
