How to find % disk used in Azure

Question

Hello there,

Greetings of the day!

We are looking for ways to identify how much % of disk capacity are in use ? If disk size is 256GB and it has only 128GB data in it, 50% of the disk size is in use for our calculations.

We are not looking for free size information at VM level, rather we want to gather that info for each disk.

Applicate your Response. Thank you!!

Hi anil kumar

You can enable VM insight through Azure portal or method of your choice

https://learn.microsoft.com/en-us/azure/azure-monitor/vm/vminsights-enable-portal

Once done you can use following KQL Query to get the details

InsightsMetrics
| where Origin == "vm.azm.ms" 
  and Namespace == "LogicalDisk" 
  and Name == "FreeSpacePercentage"
| extend Disk = tostring(todynamic(Tags)["vm.azm.ms/mountId"])
| summarize Disk_Used_Space = 100 - avg(Val) by Computer, Disk, _ResourceId
| project Computer, Disk, Disk_Used_Space
