Running Command on Azure vm via powershell

Question

I am trying to invoke powershell script via another powershell script , and i can see output on console but while extracting in csv values are null and also how can i print individual value like StandardName (for reference check output file )etc .

$report =$null
$report= @()
$vms = get-azvm  #vmname detail 
foreach( $vm in $vms){
$data =get-azvm -ResourceGroupName $vm.resourcegroupname -Name $vm.name -Status
if ( ($data.OsName -contains "Windows Server 2016 Datacenter") -and ($data.Statuses.DisplayStatus -contains "VM running") )
{
    Write-Host server name is : $data.Name
    $invoke = Invoke-AzVMRunCommand -ResourceGroupName $vm.ResourceGroupName -VMName $vm.Name -CommandId RunPowerShellScript -ScriptPath ./timezone.ps1 
    $output=$invoke.Value[0,1]
    $output
    $report_temp = new-object psobject 
    $report_temp | Add-Member -MemberType NoteProperty -Name "VM Name" -Value $data.Name
    $report_temp | Add-Member -MemberType NoteProperty -Name "Detail" -Value $output.Message
    #assiging value to variable which we had created eariler 
    #$report += $report_temp
  }
}
$report |export-csv "c:\date.csv"

Below are Output for script:

Answer 1

but while extracting in csv values are null

In this line of code $report_temp | Add-Member -MemberType NoteProperty -Name "Detail" -Value $output.Message $report_temp | Add-Member -MemberType NoteProperty -Name "Detail" -Value $output.Message , you should use $output.Message[0] instead of $output.Message (because the type of $output.Message is array, you need to use index to fetch the value; otherwise, it will not add the details to the report.)

how can i print individual value like StandardName

you'd better convert the output to json, then convert it to a custom PSCustomObject object. And you can use the properties(like StandardName) of the object.

Here is the completed code:

$report =$null
$report= @()
$vms = get-azvm   #vmname detail 
foreach( $vm in $vms){
$data =get-azvm -ResourceGroupName $vm.resourcegroupname -Name $vm.name -Status
if ( ($data.OsName -contains "Windows Server 2016 Datacenter") -and ($data.Statuses.DisplayStatus -contains "VM running") )
{
    Write-Host server name is : $data.Name
    $invoke = Invoke-AzVMRunCommand -ResourceGroupName $vm.ResourceGroupName -VMName $vm.Name -CommandId RunPowerShellScript -ScriptPath ./timezone.ps1
    $output=$invoke.Value[0,1]
    $output
    $report_temp = new-object psobject 
    $report_temp | Add-Member -MemberType NoteProperty -Name "VM Name" -Value $data.Name
    $report_temp | Add-Member -MemberType NoteProperty -Name "Detail" -Value $output.Message[0]

    #here convert the $output to json
    $temp =$output.message[0]
    $temp = $temp | ConvertTo-Json
    $temp = $temp.Replace("\n\n","\n").replace("\n\n","\n").replace("\n",";") 
    $temp = $temp.Remove($temp.LastIndexOf(";"),1) 
    $temp = $temp -replace '\s',''
    $temp = $temp -replace '\"',''
    $items = [ordered]@{}
    $temp.Split(";") | ForEach-Object {
        $key, $value = $_.Split(":")
        $items[$key] = $value
        }

    $t2 = $items | ConvertTo-Json

    #here convert the json to custom PSCustomObject object
    $b1 = $t2 | ConvertFrom-Json

    #here, add the StandardName to the report
    $report_temp | Add-Member -MemberType NoteProperty -Name "StandardName" -Value $b1.StandardName

    #assiging value to variable which we had created eariler 
    $report += $report_temp
  }
}
$report |export-csv "c:\date.csv"
