To receive email notifications before a VM shuts down, you can follow these steps depending on your cloud provider or virtualization platform:
For Azure VMs
1. Enable Auto-Shutdown: Configure the auto-shutdown feature for your VM in the Azure portal. Ensure that the scheduled shutdown time is at least half an hour later than the current time if you want notifications to work properly[1][10].2. Set Up Notifications: In the auto-shutdown settings, specify an email address to receive notifications. Users will get an email 30 minutes before the VM shuts down, allowing them to postpone the shutdown if needed[10].
3. Use Azure Logic Apps: For more customized notifications, you can create an Azure Logic App that triggers before the shutdown time. This app can retrieve VM schedules and send emails using the Office 365 Outlook connector[3][10].
For Google Compute Engine VMs
1. Use Stackdriver: While Google Compute Engine doesn't directly offer email notifications for shutdowns, you can use Stackdriver for event-driven notifications. This involves setting up alerts for specific events like maintenance or instance restarts[2].2. Custom Scripts: You can write custom scripts to detect maintenance events and send notifications. This might involve using the metadata server to detect changes in the `maintenance-event` attribute[2].
For Other Platforms (e.g., vROPS, Proxmox)
1. Configure Alerts: In platforms like vROPS, you can create custom alerts that trigger email notifications when a VM is powered off unexpectedly. This involves setting up alert definitions and notifications in the platform's management interface[5].2. Scripting for Proxmox: For Proxmox, you might need to use scripting to send email notifications during shutdowns, possibly leveraging tools like NUT for UPS-triggered shutdowns[9].
Each platform has its specific methods for handling notifications, so it's important to consult the relevant documentation for detailed setup instructions.
