It details the various check instances, their frequencies, and parameters available for monitoring applications, network experience, and device health within persistent VDIs. These policies help ServiceNow customers effectively monitor and maintain the performance and stability of their Windows persistent VDI environments. Show full answer Show less ## Application Monitoring Policies * **os.win.check-app-historical:** Collects historical application metrics every 5 minutes, including CPU and memory usage, uptime, crashes, IO usage, and service status, sending data to Metric Base. * **os.win.check-app-sccm-latest:** Gathers latest metrics for Microsoft System Center Configuration Manager app every 24 hours. Note that uptime checks run only with Local System account. ## Application Network Experience (ANE) Policies These policies monitor network metrics such as latency, packet loss, and jitter for installed Windows apps and web apps. They run every 10 minutes and send data to Metric Base and the ServiceNow instance. Limitations include use of tracert command, which does not support domain URL paths. * **os.win.check-app-dom-network-historical:** Monitors network for Windows installed apps. * **os.win.check-web-app-dom-net-historical:** Monitors network for Windows web apps. ## Device Monitoring Policies * **os.win.check-system-metrics-latest:** Collects device metrics every 24 hours, including uptime, antivirus/firewall status, disk and CPU details, updates, network, and more, sending data to the ServiceNow instance. Certain parameters require Local System account. * **os.win.check-system-metrics-historical:** Runs every 30 minutes or 5 minutes depending on parameters, collecting detailed device metrics sent to Metric Base. * **os.win.check-process-data:** Gathers data on running processes every 24 hours. * **os.win.check-sys-compliance-historical/latest:** Collects device compliance metrics every 5 minutes or 24 hours, respectively. * **os.win.check-system-executables-latest:** Retrieves all executables on device volumes every 24 hours. * **os.win.check-system-registry-latest:** Collects registry data every 24 hours. ## Key Considerations * Several check instances with parameters such as uptime and bitlockerdetails require running under the Local System account for proper data collection. * Network path monitoring uses tracert command, which does not function for URLs with domain paths. By leveraging these DEX policies, ServiceNow customers can gain comprehensive visibility and monitoring capabilities for Windows persistent VDIs, enabling proactive management of application performance, network health, and device stability within their virtual desktop environments.
