Configure auto shutdown for labs and VMs in DevTest Labs

As an Azure DevTest Labs lab owner, you can configure a schedule to shut down all the virtual machines (VMs) in your lab at a specific time of day or night. You save the cost of running machines that aren't being used.

You can also set a central auto shutdown policy to control whether lab users can schedule auto shutdown for their own individual VMs. Auto shutdown policies range from allowing VM owners to fully control their VM's shutdown schedules to allowing them no control over the schedules.

This article explains how to set auto shutdown schedules for DevTest Labs labs and for individual lab VMs. The article also describes how to set lab auto shutdown policy, and how to configure auto shutdown notifications.

Configure lab auto shutdown schedule

Auto shutdown helps minimize lab waste by shutting down all of a lab's VMs at a specific time of day or night. To view or change a lab's auto shutdown schedule, follow these steps:

  1. On the home page for your lab, select Configuration and policies.

  2. In the Schedules section of the left menu, select Auto-shutdown.

  3. On the Auto-shutdown screen, for Enabled, select On to enable auto shutdown, or Off to disable it.

  4. For Scheduled shutdown and Time zone, if you turned on auto shutdown, specify the time and time zone to shut down all lab VMs.

  5. For Send notification before auto-shutdown?, select Yes or No for the option to send a notification 30 minutes before the specified auto shutdown time. If you choose Yes, enter a webhook URL endpoint under Webhook URL or semicolon-separated email addresses under Email address where you want the notification to post or be sent. For more information, see the auto shutdown notifications section.

  6. Select Save.

By default, this schedule applies to all VMs in the lab. To remove this setting from a specific VM, if allowed by policy, open the VM's management pane and change its Auto-shutdown setting.

Note

If you update the auto shutdown schedule for your lab or a VM within 30 minutes of the previously scheduled shutdown time, the new shutdown time takes effect the next day.

Configure lab auto shutdown policy

As a lab owner, you can control cost and minimize waste in your labs by managing auto shutdown policy settings for your lab. To see how to set all lab policies, see Define lab policies in Azure DevTest Labs.

Important

Auto shutdown policy changes apply only to new VMs created in the lab, not to the already existing VMs.

  1. On the home page for your lab, select Configuration and policies.

  2. In the Schedules section of the left menu, select Auto shutdown policy.

  3. Select one of the options.

    • User sets a schedule and can opt out: Lab users can override or opt out of the lab schedule. This option grants VM owners full control to set their VMs' auto shutdown schedules.

    • User sets a schedule and cannot opt out: Lab users can override the lab schedule, but they can't opt out of the auto shutdown policy. This option ensures that every lab VM is under an auto shutdown schedule. VM owners can update the schedule time, and set up shutdown notifications.

    • User has no control over the schedule set by lab administrator: Lab users can't alter or opt out of the lab auto shutdown schedule. This option gives the lab administrator complete control of the schedule for all lab VMs. VM owners can still set up auto shutdown notifications for their VMs.

  4. Select Save.

Configure VM auto shutdown settings

Depending on the auto shutdown policy, you can also set an auto shutdown schedule for individual lab VMs.

  1. On the home page for the VM, in the Operations section on the left menu, select Auto-shutdown.

  2. On the Auto-shutdown screen, for Enabled, select On to enable auto shutdown, or Off to disable it.

  3. For Scheduled shutdown and Time zone, if you turned on auto shutdown, specify the time and time zone to shut down all lab VMs.

  4. For Send notification before auto-shutdown?, select Yes or No for the option to send a notification 30 minutes before the specified auto shutdown time. If you choose Yes, enter a webhook URL endpoint under Webhook URL or an email address under Email address where you want the notification to post or be sent. For more information, see the auto shutdown notifications section.

  5. Select Save.

View activity logs for auto shutdown updates

After you update auto shutdown settings, you can see the activity logged in the activity log for the VM.

  1. On the home page for the VM, select Activity log from the left menu.

  2. Remove the Resource filter, apply the appropriate Resource group filter, and view the entries for Add or modify schedules.

  3. Select the Add or modify schedules operation to open a summary page that shows more details about the operation.

Auto shutdown notifications

When you enable notifications in auto shutdown configuration, lab users receive a notification 30 minutes before auto shutdown if any of their VMs will be affected. The notification gives users a chance to save their work before the shutdown. If the auto shutdown settings specify an email address, the notification sends to that email address. If the settings specify a webhook, the notification sends to the webhook URL.

The notification can also provide links that allow the following actions for each VM if someone needs to keep working:

  • Skip the auto shutdown this time.
  • Snooze the auto shutdown for an hour.
  • Snooze the auto shutdown for 2 hours.

You can use webhooks to implement your own notifications. You set up integrations that subscribe to certain events. When one of those events happens, an HTTP POST payload sends to the webhook's URL.

Apps like Azure Logic Apps and Slack have extensive support for webhooks. For more information about responding to webhooks, see Azure Functions HTTP triggers and bindings overview and Add an HTTP trigger for Azure Logic Apps.

The following example shows you how to use Logic Apps to configure an auto shutdown notification that sends an email to VM owners.

Create a logic app that sends email notifications

Logic Apps provides many connectors that make it easy to integrate a service with other clients, like Office 365 and Twitter. At a high level, the steps to set up a Logic App for email notification are:

  1. Create a logic app.
  2. Configure the built-in template.
  3. Integrate with your email client.
  4. Get the Webhook URL to use in auto shutdown notification settings.

To get started, create a logic app in Azure with the following steps:

  1. In the Azure portal, enter logic apps into the top Search field, and then select Logic apps.

  2. At the top of the Logic apps page, select Add.

  3. On the Create Logic App page:

    • Select your Azure Subscription.
    • Select a Resource Group or create a new one.
    • Enter a Logic App name.
    • Select a Region for the logic app.
