How to find/query disk growth for Windows VM

Hi,

I have to calculate Disk "% Growth" for Windows & Linux VMs.

 

By referring earlier articles/Conversation, I am able to get details/data for Free_Space & Used_Space. Now I have to write a query for "% Growth" and "Growth % ABS".

 

Is any available counter or way to write Log query?

    Are you looking for % change per day?  

    Perf
    | where TimeGenerated > startofday(ago(7d))
    | where Computer == "VM01"
    | where CounterName == "Free Megabytes" and InstanceName == "_Total" 
    | summarize max(CounterValue) by Computer, bin(TimeGenerated, 1d)
    | order by Computer asc, TimeGenerated asc
    | extend changeInMb = max_CounterValue  - prev(max_CounterValue, 1)
    | extend pctChange = (changeInMb * 100) / prev(max_CounterValue,1)
