What should be configured to generate alerts based on session host performance and usage in Azure Virtual Desktop?

To generate alerts based on session host performance and usage in Azure Virtual Desktop, configuring Azure Virtual Desktop Insights is the most effective option. Azure Virtual Desktop Insights provides comprehensive monitoring and analytics capabilities tailored specifically for Azure Virtual Desktop environments. It leverages metrics and log data to offer insights into session host performance, user sessions, and application usage.

By utilizing Azure Virtual Desktop Insights, administrators can set up alerts based on specific performance metrics such as CPU usage, memory consumption, and number of active user sessions. These alerts help maintain optimal performance and user experience by notifying administrators of potential issues proactively.

In contrast, while a scaling plan can manage resources based on load, it does not provide the detailed monitoring and alerting capabilities necessary for performance and usage insights. Tags are useful for organizing Azure resources but do not offer metrics or insights related to performance. Microsoft Sentinel, while a strong tool for security analytics and threat detection, is not specifically designed for performance monitoring in Azure Virtual Desktop environments. Therefore, Azure Virtual Desktop Insights is the most suited tool for generating alerts regarding session host performance and usage.
