In this video, I walk through setting up the Azure Monitor solution for Windows Virtual Desktop Spring Update.  The video starts by setting up a Log Analytics workspace, then adding the Session Hosts to send performance data to the Log Analytics Workspace.  After that, Azure Diagnostic data is configuring to send data to Log Analytics.  Lastly, the Workbook available from Microsoft is deployed to view WVD performance and session information.
