Exercise - Trigger a logic app by using Event Grid

Completed

One easy way to use Azure Event Grid is to include it in a logic app.

Suppose you've chosen to use Event Grid to alert your administrators when a virtual machine is reconfigured.

Here, you'll set up a virtual machine and create a logic app with an Event Grid trigger that responds to the events produced by the virtual machine.

Create a virtual machine

Let's start by creating a new virtual machine in the Azure portal.

1. Sign in to the Azure portal with the account that you used to activate the sandbox.

2. In resource menu or on the home page, under Azure services, select Create a resource. The Create a resource pane appears.

3. In the Create a resource pane, enter Virtual machine in global search. In the search results, select Virtual machine published by Microsoft for Azure, and then select Create.

4. On the Basics tab, enter the following values for each setting:

   Setting	Value
   Project details
   Subscription	Concierge subscription
   Resource group	From the dropdown list, select [sandbox resource group]
   Instance details
   Virtual machine name	vm1
   Region	Choose from the free sandbox regions listed after this table.
   Availability options	No infrastructure redundancy required
   Security type	Standard
   Image	Windows Server 2019 Datacenter - x64 Gen2
   Run with Azure Spot discount	No checkmark
   Size	Standard DS1 v2
   Administrator account
   Username	vmadmin
   Password	Enter a complex password
   Inbound port rules
   Public inbound ports	None

   The free sandbox allows you to create resources in a subset of the Azure global regions. Select a region from the following list when you create resources:

   • West US 2
   • South Central US
   • Central US
   • East US
   • West Europe

   • Southeast Asia
   • Japan East
   • Brazil South
   • Australia Southeast
   • Central India

5. Select Review and create. Once validation passes, select Create.

   Wait for deployment to complete, and then select Go to resource. The Overview pane for vm1 Virtual machine appears.

Create a logic app

Let's create a logic app that runs whenever a virtual machine change is detected. First, we'll create a blank logic app.

1. In the resource menu, select Create a resource. The Create a resource pane appears.

2. In the Create a resource menu, select Integration, and then in the results list, select Logic App. The Create Logic App pane appears.

3. On the Basics tab, enter the following values for each setting.

   Setting	Value
   Project Details
   Subscription	Concierge subscription
   Resource group	From the dropdown list, select [sandbox resource group]
   Instance Details
   Logic app name	Enter a name
   Region	Choose from the free sandbox regions listed after this table.
   Enable log analytics	No
   Plan type	Consumption

   The free sandbox allows you to create resources in a subset of the Azure global regions. Select a region from the following list when you create resources:

   • West US 2
   • South Central US
   • Central US
   • East US
   • West Europe

   • Southeast Asia
   • Japan East
   • Brazil South
   • Australia Southeast
   • Central India

4. Select Review + create, then select Create.

5. Wait for deployment to complete, then select Go to resource. The Overview pane appears.

Add an Event Grid trigger to the logic app

1. In the menu on the left, select Logic app designer in the Development Tools section.

2. Scroll down to Templates section, then select Blank Logic App. The Logic Apps Designer pane appears.

   

3. In the Search connectors and triggers search box, enter Event Grid as your filter. From the list of triggers, select When a resource event occurs.

   

4. When prompted, sign in to the Microsoft Learn Sandbox organization using your Azure account credentials.

5. The When a resource event occurs dialog box appears. Select the following values for each setting to subscribe your logic app to publisher events:

   Setting	Value
   Subscription	Concierge Subscription
   Resource Type	Microsoft.Resources.ResourceGroups
   Resource Name	[sandbox resource group]
   Event Type Item - 1	Choose Microsoft.Resources.ResourceActionSuccess from the drop-down, then select Add new item
   Event Type Item - 2	Choose Microsoft.Resources.ResourceDeleteSuccessfrom the drop-down, then select Add new item
   Event Type Item - 3	Choose Microsoft.Resources.ResourceWriteSuccess from the drop-down.

   

6. On the command bar, select Save.

   

Your logic app is now ready and set up to be a subscriber to the events from the Azure Event Grid.
