Monitor Azure AI Services

Azure AI Services can be a critical part of an overall application infrastructure. It’s important to be able to monitor activity and get alerted to issues that may need attention.

Clone the repository for this course

If you have already cloned AI-102-AIEngineer code repository to the environment where you’re working on this lab, open it in Visual Studio Code; otherwise, follow these steps to clone it now.

  1. Start Visual Studio Code.
  2. Open the palette (SHIFT+CTRL+P) and run a Git: Clone command to clone the repository to a local folder (it doesn’t matter which folder).
  3. When the repository has been cloned, open the folder in Visual Studio Code.
  4. Wait while additional files are installed to support the C# code projects in the repo.

    Note: If you are prompted to add required assets to build and debug, select Not Now.

Provision an Azure AI Services resource

If you don’t already have one in your subscription, you’ll need to provision an Azure AI Services resource.

  1. Open the Azure portal at, and sign in using the Microsoft account associated with your Azure subscription.
  2. In the top search bar, search for Azure AI services, select Azure AI Services, and create an Azure AI services multi-service account resource with the following settings:
    • Subscription: Your Azure subscription
    • Resource group: Choose or create a resource group (if you are using a restricted subscription, you may not have permission to create a new resource group - use the one provided)
    • Region: Choose any available region
    • Name: Enter a unique name
    • Pricing tier: Standard S0
  3. Select any required checkboxes and create the resource.
  4. Wait for deployment to complete, and then view the deployment details.
  5. When the resource has been deployed, go to it and view its Keys and Endpoint page. Make a note of the endpoint URI - you will need it later.

Configure an alert

Let’s start monitoring by defining an alert rule so you can detect activity in your Azure AI services resource.

  1. In the Azure portal, go to your Azure AI services resource and view its Alerts page (in the Monitoring section).
  2. Select + Create dropdown, and select Alert rule
  3. In the Create an alert rule page, under Scope, verify that the your Azure AI services resource is listed. (Close Select a signal pane if open)
  4. Select Condition tab, and click on the See all signals link to show the Select a signal pane that appears on the right, where you can select a signal type to monitor.
  5. In the Signal type list, select Activity Log, and then in the filtered list, select List Keys.
  6. Review the activity over the past 6 hours.
  7. Select the Actions tab. Note that you can specify an action group. This enables you to configure automated actions when an alert is fired - for example, sending an email notification. We won’t do that in this exercise; but it can be useful to do this in a production environment.
  8. In the Details tab, set the Alert rule name to Key List Alert.
  9. Select Review + create.
  10. Review the configuration for the alert. Select Create and wait for the alert rule to be created.
  11. In Visual Studio Code, right-click the 03-monitor folder and open an integrated terminal. Then enter the following command to sign into your Azure subscription by using the Azure CLI.

    az login

    A web browser tab will open and prompt you to sign into Azure. Do so, and then close the browser tab and return to Visual Studio Code.

    Tip: If you have multiple subscriptions, you’ll need to ensure that you are working in the one that contains your Azure AI services resource. Use this command to determine your current subscription.

    az account show

    If you need to change the subscription, run this command, changing <subscriptionName> to the correct subscription name.

    az account set --subscription <subscriptionName>
  12. Now you can use the following command to get the list of Azure AI services keys, replacing <resourceName> with the name of your Azure AI services resource, and <resourceGroup> with the name of the resource group in which you created it.

    az cognitiveservices account keys list --name <resourceName> --resource-group <resourceGroup>

The command returns a list of the keys for your Azure AI services resource.

  1. Switch back to the browser containing the Azure portal, and refresh your Alerts page. You should see a Sev 4 alert listed in the table (if not, wait up to five minutes and refresh again).
  2. Select the alert to see its details.

Visualize a metric

As well as defining alerts, you can view metrics for your Azure AI services resource to monitor its utilization.

  1. In the Azure portal, in the page for your Azure AI services resource, select Metrics (in the Monitoring section).
  2. If there is no existing chart, select + New chart. Then in the Metric list, review the possible metrics you can visualize and select Total Calls.
  3. In the Aggregation list, select Count. This will enable you to monitor the total calls to you Azure AI Service resource; which is useful in determining how much the service is being used over a period of time.
  4. To generate some requests to your Azure AI service, you will use curl - a command line tool for HTTP requests. In Visual Studio Code, in the 03-monitor folder, open rest-test.cmd and edit the curl command it contains (shown below), replacing <yourEndpoint> and <yourKey> with your endpoint URI and Key1 key to use the Text Analytics API in your Azure AI services resource.

     curl -X POST "<yourEndpoint>/text/analytics/v3.1/languages?" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: <yourKey>" --data-ascii "{'documents':           [{'id':1,'text':'hello'}]}"
  5. Save your changes, and then in the integrated terminal for the 03-monitor folder, run the following command:


The command returns a JSON document containing information about the language detected in the input data (which should be English).

  1. Re-run the rest-test command multiple times to generate some call activity (you can use the ^ key to cycle through previous commands).
  2. Return to the Metrics page in the Azure portal and refresh the Total Calls count chart. It may take a few minutes for the calls you made using curl to be reflected in the chart - keep refreshing the chart until it updates to include them.

More information

One of the options for monitoring Azure AI services is to use diagnostic logging. Once enabled, diagnostic logging captures rich information about your Azure AI services resource usage, and can be a useful monitoring and debugging tool. It can take over an hour after setting up diagnostic logging to generate any information, which is why we haven’t explored it in this exercise; but you can learn more about it in the Azure AI Services documentation.
