Hi, does anyone can explain why there is a discrepancy in the Output of the Powershell script when I used Get-AzMetric command in obtaining the data from the Azure Performance Metrics Portal?

    Hi @Jessah Mae Alogon

    I think the reason these two results are different is because the time granularity is different. If you change the -TimeGrain, you can get different values. I am not sure the default values of time granularity in azure vm service. You can try 24hours for testing.
