Hi Team,

Could you please provide us the powershell script for enabling alerts for all PaaS resources in Azure?

We have around 40K PaaS resources in our Azure estate.

Kindly help us with this.

    Hi @Akash Chopra ,

    Thanks for posting this question in Microsoft Q&A platform and for using Azure services.

    As I understand from the question, you need a PowerShell script for enabling alerts for all PaaS resources in Azure.

    Please check below if this helps in your use-case:

    [CmdletBinding()]  
    param (  
        # ResourceGroup to operate on.  
        [Parameter(Mandatory=$true)]  
        [string]  
        $ResourceGroupName,  
        <# Switch parameter to either enable or disable all rules, default value   
            is false if not supplied when calling the script. #>  
        [switch]  
        $Enable  
        )  
      
    # Get all the rules for the given Resource Group.  
    $alertRules = @(Get-AzureRmAlertRule -ResourceGroupName $ResourceGroupName);  
    
    <# Function reads the array and enables all rules in the array. If a rule is already enabled,  
        it will stay enabled. #>   
    function Enable-AllRules {  
        param([string]$RG)  
        foreach ($rule in $alertRules) {  
            Add-AzureRmMetricAlertRule `  
                -ResourceGroupName $RG `  
                -TargetResourceId $rule.Condition.DataSource.ResourceUri `  
                -Location $rule.Location `  
                -Name $rule.AlertRuleResourceName `  
                -Description $rule.Description `  
                -MetricName $rule.Condition.DataSource.MetricName `  
                -Operator $rule.Condition.OperatorProperty `  
                -Threshold $rule.Condition.Threshold `  
                -WindowSize $rule.Condition.WindowSize `  
                -TimeAggregationOperator $rule.Condition.TimeAggregation;  
        }  
    }  
      
    switch ($Enable) {  
        $true { Enable-AllRules -RG $ResourceGroupName; }  
        Default { Disable-AllRules -RG $ResourceGroupName; }  
    }

    Hi @Akash Chopra ,

    You have not specified what type of alert is required but any of the alerts are specified either at resource, resource group or subscription.
    If you want to have the same alert on multiple subscriptions create the same alert on those subscriptions.
    If you are sending your monitoring data from multiple resources in different subscriptions to Log Analytics workspace you can create Log Alert scoped to the workspace and that way you will get alerted on any resource that sends data to the Log Analytics workspace.

    Hope this should help. Do let us know if further queries.
    Thanks.
