Create Azure Service Health Alerts for All Resource Groups

[Guest wernerrall]

Introduction

 

I recently had a customer requirement for creating Azure Service Health Alerts. The way access was provided in Azure, meant that only specific users had access to their respective Resource Groups. We also did not want these users to receive alerts for all Resources in the Subscription [Default scope for Service Health Alerts].

 

 

 

Process Description:

 

This led to the creation of a PowerShell Script that will cycle through each Resource Group and create Service Health Alerts for all Contributors or Owners.

 

 

Script Explanation

 

*Please only run this script in PowerShell 7 and above as I am using the -Parallel switch

 

1. Breaking the script into a few different sections, we will start by connecting to Azure and getting a list of all subscriptions
   

 

 

 

 

 

 

1. Then we will kick off a few Parallel processes to speed things up. These jobs will change context for each subscription and then find all resource groups
   

 

 

 

 

 

 

1. Now we will find all Contributors on the resource group. If there are none we will look for Owners. We are only looking for objects that have a SignInName as we will need that for our email address assignment.
   

 

 

 

 

 

 

1. By using the ARM Template for Health Alerts we can create a deployment with some parameters which I am randomizing the numbers for.
   

 

 

 

 

 

 

1. If we take a closer look at the ARM Template one of the original problems were that this could only be assigned to the subscription().id scope
   

 

 

 

 

 

 

 

 

But by added two new parameters and modifying the scope I could get it to apply on ResourceGroup Level

 

 

 

 

 

 

 

 

Running the Script

 

 

 

1. Simply grab the PowerShell from my GitHub Repo and save it into a PS1 file.
   

 

 

 

 

 

 

 

 

1. Launch a PowerShell 7 or newer session, change directory to your ps1 file and run.
   

 

 

 

 

 

 

 

 

1. The PowerShell session will launch an Azure Window to Authenticate you
   

 

 

 

 

 

 

 

 

 

 

 

You might see some warnings as I am not hiding any errors.

 

 

 

 

 

 

On Success you should see the ARM Template deployed.

 

 

 

 

 

 

We can confirm the deployment ran by looking in the deployments section of the resource group

 

 

 

 

 

 

 

 

 

Also if we go into Service Heath and click on Health Alerts we will see all our newly created alerts.
