how can I get all my VM CPU utilization witch is present in one resource group

Question

To monitor and retrieve CPU utilization for all your Virtual Machines (VMs) in a specific Azure Resource Group, you can use Azure PowerShell. Please guide us step-by-step.

Hello Gazanfar,

You can use the following PS script cited from here by vipullag-MSFT:

#get all vms in a subscription
$vms = Get-AzVM -ResourceGroupName "ResourceGroupName"

 #get the last 3 days data
 #end date
 $et=Get-Date

 #start date
 $st=$et.AddDays(-3)

  $arr =@()

 foreach($vm in $vms)
 {
 
 $s = ""
 
 #percentage cpu usage
$cpu = Get-AzMetric -ResourceId $vm.Id -MetricName "Percentage CPU" -DetailedOutput -StartTime $st `
 -EndTime $et -TimeGrain 12:00:00  -WarningAction SilentlyContinue


 
 # 3 days == 72hours == 12*6hours

 $cpu_total=0.0
 
 foreach($c in $cpu.Data.Average)
 {
  #this is a average value for 12 hours, so total = $c*12 (or should be $c*12*60*60)
  $cpu_total += $c*12
 }


 # add all the related info to the string
 $s = "VM Name: " + $vm.name + "; Resource Group: " + $vm.ResourceGroupName + "; CPU: " +$cpu_total

 # add the above string to an array
 $arr += $s
 }

 #check the values in the array
 $arr

Hopefully this helps you. You may need to edit some variables, but this grabs for all VMs in subscription's resource group. (this checks the last 3 days).

I have made adjustments to the code to include specifically for a Resource Group.
