Powershell Script to download Azure recommendations - azure

Question

Login-AzAccount
$subs= az account list --query '[*].id'
Get-AzAdvisorRecommendation list --subscription $subs
I need to download the list of Azure recommendations on a tenant which will be having multiple subscriptions using Powershell script

Answer 1

Get-AzAdvisorRecommendation list --subscription $subs
Instead of --subscription you need to pass -subscription as a parameter to Get-AzAdvisorRecommendation cmdlet.
As per the Azure PowerShell cmdlet documentation, The Cmdlet Get-AzAdvisorRecommendation doesnt have any flag -subscription as parameter.
You can use this below script to pull the azure advisor recommendations for all subscriptions under a particular tenant.
$list=#()
$sub=get-azsubscription
Write-Output $sub
foreach( $item in $sub){
Set-AzContext -Subscription $item.Id -Tenant $item.TenantId -Force
$rg=Get-AzResourceGroup
foreach($r in $rg){
$list+=Get-AzAdvisorRecommendation -ResourceGroupName $r.ResourceGroupName
}
}
$list | Export-Csv C:\Users\list.csv
Here is the sample output for reference:
While testing the above script in our local environment, we have passed a single subscription to the cmdlet Get-azsubscription using the -subscriptionId flag.

Using this updated script, I can download the recommendations as well, thanks Venkatesh for your inputs.
