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-policies-persistent-vdis__section_lnp_r1b_bxb}

DEX provides the following policies for persistent VDI applications.{#dex-policies-persistent-vdis__table_hxg_t1b_bxb__entry__5}

| Check instance | Description | Frequency | Historical or latest | Check instance parameters\* |
|-|-|-|-|-|
| os.win.check-app-historical | Collects the application metrics on the persistent VDI Windows device and sends the metric data to MetricBase. | 5 minutes | Historical | cpu_usage, memory_usage, uptime, last_access_time, crashes, io_usage_read, io_usage_write, is_running, freezes, zscaler_service_status |
| os.win.check-app-sccm-latest | Collects application-specific metrics for the Microsoft System Center Configuration Manager app on the persistent VDI Windows device. | 24 hours | Latest | Not applicable |
| Important: \* DEX Windows Apps Metrics with the uptime check instance parameter only runs with the Local System account. |||||
