Azure webhook get VM status - azure

Question

I'm trying to do a runbook/webhook that return a status of machine. What I finally notices is that
Get-AzureRmVM
is only returning 2 resource groups. Where
Get-AzureRmResource
Does return many more but not all of them again!
I'm sure about my Resource Group Name but still it says resource group 'groupName' could not be found. when I try to run with specific name
Get-AzureRmVM -ResourceGroupName groupName
While my other start and stop runbook works just fine, so i'm confused I can't see the difference between the groups.
PS: I'm using Azure Run As Connection
param
(
[Parameter (Mandatory = $false)]
[object] $WebhookData
)
if ($WebhookData) {
$vms = (ConvertFrom-Json -InputObject $WebhookData.RequestBody)
Write-Output "Authenticating to Azure with service principal and certificate"
$ConnectionAssetName = "AzureRunAsConnection"
Write-Output "Get connection asset: $ConnectionAssetName"
$Conn = Get-AutomationConnection -Name $ConnectionAssetName
if ($Conn -eq $null)
{
throw "Could not retrieve connection asset: $ConnectionAssetName. Check that this asset exists in the Automation account."
}
Write-Output "Authenticating to Azure with service principal."
Add-AzureRmAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint | Write-Output
# Start each virtual machine
foreach ($vm in $vms)
{
$vmName = $vm.Name
Write-Output "Checking $vmName"
$vmstatus = Get-AzureRmVM -Name $vm.Name -ResourceGroupName $vm.ResourceGroup -Status# | Select-Object -ExpandProperty StatusesText | ConvertFrom-Json
#select code index and convert to $vmpowerstate
$vmPowerState = $vmstatus#[1].Code
#Write-Output "Resource Group: $vmResourceGroupName", ("VM Name: " + $VM.Name), "Status: $VMStatusDetail" `n
Write-Output ("VM Name: " + $vmName), "Status: $vmPowerState" `n
}
}
else {
write-Error "This is webhook only."
}

Answer 1

Because your resource groups are in the different subscriptions.
As #et3rnal mentioned,
I have 2 subscriptions and Get-AzureRmVM returning 2 vms only because the rest are classics. The automation account I created this runbook at is the other one and I can see that in the overview? its the same one I use to start/stop machines in the other subscription!
Update:
If you want to get the PowerState of the VM, you could try the command below, in your case, just put it in the loop, the $PowerState is the PowerState.
$status = Get-AzureRmVM -Name <VM Name> -ResourceGroupName <Resource Group Name> -Status
$PowerState = ($status.Statuses | Where-Object {$_.Code -like "PowerState/*"}).DisplayStatus
Update2:
1.For the classic VM, we need to use azure ASM powershell module command, you could try Get-AzureVM, may be the Example 3: Display a table of virtual machine statuses in that link will help.
2.Another option is to migrate the classic VM(ASM) to ARM, then use the ARM command Get-AzureRmVM.
