reference brazil Updated Oct 1, 2026 1 min read recommended-policies-np-vdis.md

VDI policy and VDI configuration file records to activate on your instance so that DEX can monitor non-persistent (NP) Virtual Desktop Infrastructures (VDIs).

Configure these records as described in Prepare agent deployment on a non-persistent virtual desktop infrastructure machine.

Note: For each record listed in this topic, make sure Active is set to true.

VDI policies

Configure the following records in the VDI Policies [sn_agent_vdi_policy] table.

Policy	Used for
Enhanced Discovery Policy	SaaS and installed usage
VISC Get application metric	SaaS and installed usage
SAM background policy (Non OsqueryD)	SaaS and installed usage
VISC Get browser extension init	SaaS and installed usage
VISC Get browser extension device init	SaaS and installed usage
SAM discovery	SaaS and installed usage
DEX NP VDI Windows Device Metrics	DEX performance metrics
DEX NP VDI Windows Apps Metrics	DEX performance metrics
DEX Local Metric Tag Enrichment	DEX performance metrics. Requires version 4.3.2 or later.
DEX Metrics Reporter	DEX performance metrics
DEX Metric Aggregations	DEX performance metrics

VDI configuration files

Configure the following records in the VDI Configuration Files [sn_agent_vdi_config_file] table.

Configuration file	Used for
AccVisMonitoredUrls	SaaS and installed usage
MonitoredServiceApps	SaaS and installed usage
DEXAgentSystemConfig	DEX performance metrics
DEXMetricEnrichmentSchema	DEX performance metrics
DEXMetricRulesConfig	DEX performance metrics
DEXMonitoredInstalledApps	DEX performance metrics
DEXAdvancedAppMonitoringConfig	DEX performance metrics

For the check instances, frequencies, and parameters that these policies run, see DEX policies for non-persistent VDIs.

To configure the agent on the golden image, see Enable a non-persistent virtual desktop infrastructure agent.
