A Practical Guide to Handling Azure Alerts During Planned Maintenance

Problem description Availability alerts for VMs in a resource group were configured. During planned maintenance (for example, a VM reboot), the team receives VM availability notifications that are false positives. How can we avoid or resolve these false alarms? Approaches The alert in question uses VM availability metrics evaluated every 1 minute with a 5‑minute lookback window. Option 1 — Disable the alert during the maintenance window When you stop the VM, disable the alert. When you start the VM, re-enable the alert. This is a simple approach but requires coordinating the start/stop process with alert management.
