Hello Vinoth Kaliaperumal

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

For your ask "I need to pull CPU usage report of all the virtual machines present in a subscription."

As mentioned in previous response, there is not straight way from Azure Portal.

You can do this using scripting. I just tried this using a powershell script and it works. Please note that this is a sample script and you may need to add/modify based on your need.

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

 #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

Hope this helps.

Answer 2

Here is the way in which you can monitor the cpu usage of the virtual machine. It uses Azure VM Metrics

1. Go to the VM resource that you are interested in
2. Go to Monitoring > Metrics
3. Select the scope you are interested in
4. Configure the filters to show the data you would like to see
5. Click on Save to dashboard and then select Pin to dashboard
6. Either use an existing dashboard or create a new dashboard
7. Pin additional metrics from other resources/scopes as needed
