# DEX policies for persistent VDIs

DEX policies for Windows persistent Virtual Desktop Infrastructures \(VDIs\) define the 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 MetricBase and the ServiceNow instance.|10 minutes|Historical|domain\_network\_details|
|os.win.check-web-app-dom-net-historical|Collects Windows web apps network monitoring metrics like latency, packet loss, and jitter and sends monitoring data to MetricBase and the ServiceNow instance.|10 minutes|Historical|domain\_network\_details|
