Lab 11 - Implement Monitoring

Lab introduction

In this lab, you learn about Azure Monitor. You learn to create an alert and send it to an action group. You trigger and test the alert and check the activity log.

This lab requires an Azure subscription. Your subscription type may affect the availability of features in this lab. You may change the region, but the steps are written using East US.

Estimated timing: 40 minutes

Lab scenario

Your organization has migrated their infrastructure to Azure. It is important that Administrators are notified of any significant infrastructure changes. You plan to examine the capabilities of Azure Monitor, including Log Analytics.

Interactive lab simulation

There is an interactive lab simulation that you might find useful for this topic. The simulation lets you to click through a similar scenario at your own pace. There are differences between the interactive simulation and this lab, but many of the core concepts are the same. An Azure subscription is not required.

  • Implement monitoring. Create a Log Analytics workspace and Azure-automation solutions. Review monitoring and diagnostic settings for virtual machines. Review Azure Monitor and Log Analytics functionality.

Task 3: Configure action group notifications

In this task, if the alert is triggered send an email notification to the operations team.

  1. Continue working on your alert. Select Next: Actions, and then select Create action group.

    Did you know? You can add up to five action groups to an alert rule. Action groups are executed concurrently, in no specific order. Multiple alert rules can use the same action group.

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

    Setting Value
    Project details  
    Subscription your subscription
    Resource group az104-rg11
    Region Global (default)
    Instance details  
    Action group name Alert the operations team (must be unique in the resource group)
    Display name AlertOpsTeam
  3. Select Next: Notifications and enter the following values for each setting.

    Setting Value
    Notification type Select Email/SMS message/Push/Voice
    Name VM was deleted
  4. Select Email, and in the Email box, enter your email address, and then select OK.

    Note: You should receive an email notification saying you were added to an action group. There may be a few minutes delay, but that is a sure sign the rule has deployed.

  5. Once the action group is created move to the Next: Details tab and enter the following values for each setting.

    Setting Value
    Alert rule name VM was deleted
    Alert rule description A VM in your resource group was deleted
  6. Select Review + create to validate your input, then select Create.

Task 4: Trigger an alert and confirm it is working

In this task, you trigger the alert and confirm a notification is sent.

Note: If you delete the virtual machine before the alert rule deploys, the alert rule might not be triggered.

  1. In the portal, search for and select Virtual machines.

  2. Check the box for the az104-vm0 virtual machine.

  3. Select Delete from the menu bar.

  4. Check the box for Apply force delete. Enter delete to confirm and then select Delete.

  5. In the title bar, select the Notifications icon and wait until vm0 is successfully deleted.

    Setting Value
    Resource group az104-rg11
    Rule name Planned Maintenance
    Description Suppress notifications during planned maintenance.
  7. Select Review + create to validate your input, then select Create.

Task 6: Use Azure Monitor log queries

In this task, you will use Azure Monitor to query the data captured from the virtual machine.

  1. In the Azure portal, search for and select Monitor blade, click Logs.

  2. If necessary close the splash screen.

  3. Select a scope, your resource group. Select Apply.

  4. In the Queries tab, select Virtual machines (left pane).

  5. Review the queries that are available. Run (hover over the query) the Count heartbeats query.

  6. You should receive a heartbeat count for when the virtual machine was running.

  7. Review the query. This query uses the heartbeat table.

  8. Replace the query with this one, and then click Run. Review the resulting chart.

     InsightsMetrics
     | where TimeGenerated > ago(1h)
     | where Name == "UtilizationPercentage"
     | summarize avg(Val) by bin(TimeGenerated, 5m), Computer //split up by computer
     | render timechart
    
  9. As you have time, review and run other queries.

    Did you know?: If you want to practice with other queries, there is a Log Analytics Demo Environment.

    Did you know?: Once you find a query you like, you can create an alert from it.

Cleanup your resources

If you are working with your own subscription take a minute to delete the lab resources. This will ensure resources are freed up and cost is minimized. The easiest way to delete the lab resources is to delete the lab resource group.

  • In the Azure portal, select the resource group, select Delete the resource group, Enter resource group name, and then click Delete.
  • Using Azure PowerShell, Remove-AzResourceGroup -Name resourceGroupName.
  • Using the CLI, az group delete --name resourceGroupName.

Key takeaways

Congratulations on completing the lab. Here are the main takeaways for this lab.

  • Alerts help you detect and address issues before users notice there might be a problem with your infrastructure or application.
  • You can alert on any metric or log data source in the Azure Monitor data platform.
  • An alert rule monitors your data and captures a signal that indicates something is happening on the specified resource.
  • An alert is triggered if the conditions of the alert rule are met. Several actions (email, SMS, push, voice) can be triggered.
  • Action groups include individuals that should be notified of an alert.
