You plan to use the Start/Stop VMs during off-hours feature and need automatic shutdown of session hosts based on CPU utilization. What must you configure on the session hosts?

The Start/Stop VMs during off-hours feature relies on Azure Monitor metrics for its auto-scaling capabilities, including CPU utilization. To enable the feature to collect and act upon CPU utilization data from your session hosts, you must configure Diagnostic settings for those VMs. This directs performance counters, like CPU usage, to a Log Analytics workspace, which the Start/Stop feature then queries. Installing the Azure Virtual Desktop Agent is necessary for the session host to function within AVD, but it doesn't directly enable CPU-based auto-shutdown for this specific feature. Enabling change tracking is for monitoring configuration changes, not performance metrics. Configuring Power Management settings within the guest OS is generally for individual VM power states, not for integration with Azure's auto-scaling features based on performance metrics.
