Azure Monitor

Overview

Azure Monitor provides full-stack monitoring, advanced analytics, and intelligent insights for your applications and infrastructure.

Real-life Use Cases

• Cloud Architect: Design centralized monitoring for multi-region deployments.
• DevOps Engineer: Set up alerts for auto-scaling and incident response.

Terraform Example

resource "azurerm_monitor_action_group" "alerts" {
  name                = "devops-alerts"
  resource_group_name = var.resource_group
  short_name          = "alerts"
  email_receiver {
    name          = "devops"
    email_address = "devops@example.com"
  }
}

Bicep Example

resource actionGroup 'Microsoft.Insights/actionGroups@2022-06-15' = {
  name: 'devops-alerts'
  location: 'Global'
  properties: {
    groupShortName: 'alerts'
    emailReceivers: [
      {
        name: 'devops'
        emailAddress: 'devops@example.com'
      }
    ]
  }
}

Azure CLI Example

az monitor action-group create --resource-group my-rg --name devops-alerts --short-name alerts --action email devops devops@example.com

Best Practices

• Centralize logs and metrics.
• Use action groups for alerting.

Common Pitfalls

• Not setting log retention policies.
• Too many noisy alerts.

Joke: Why did Azure Monitor break up with the VM? Too many signals, not enough commitment!
