# DEX policies for persistent VDIs

Policy reference for DEX monitoring on Windows persistent Virtual Desktop Infrastructures \(VDI\). Use this reference to understand available check instances, frequencies, and parameters for application, network, and device monitoring.

## Policies for Windows persistent VDIs — Application

DEX provides the following policies for persistent VDI applications.

</table>## Policies for Windows persistent VDIs — Application Network Experience

**Note:** These policies have the following limitations:

-   A tracert command is used to get the network path.
-   ANE doesn't work for path in the domain URL. Example: &lt;domain&gt;/&lt;path&gt;

DEX provides the following policies for persistent VDIs applications.

|Check instance|Description|Frequency|Historical or latest|Check instance parameters|
|--------------|-----------|---------|--------------------|-------------------------|
|os.win.check-app-dom-network-historical|Collects Windows installed apps network monitoring metrics like latency, packet loss, and jitter and sends monitoring data to Metric Base and the ServiceNow® instance.|10 mins|Historical|domain\_network\_details|
