Azure Monitor for Windows Virtual Desktop public preview

Hi Logan_Silliman

I am trying to understand the best way to price the Log Analytics / Azure monitor cost when we use the Azure Monitor for WVD workbook / solution. Should we price the no of session host VMs or the user desktops as the data source? I believe they should be session host VMs but I am keen to confirm that. Also, is there any technique towards estimating the amount of log data this will generate (for Log Analytics ingestion pricing). Many thanks.
