Microsoft Azure provides a wide range of services to cater to various business needs. Among these, Azure Files is a popular choice for creating, sharing, and managing file shares in the cloud. However, to ensure optimal performance and availability, it’s crucial to monitor your Azure Files service effectively. This blog post will provide a detailed, step-by-step guide on how to set up monitoring for Azure Files.

Understanding Azure Files

Azure Files is a managed file storage service provided by Microsoft Azure. It supports both Server Message Block (SMB) and Network File System (NFS) protocols, making it compatible with a wide range of applications and platforms. Azure Files provides identity-based authentication and access control through Azure Active Directory (Azure AD) and Shared Access Signatures (SAS).

Why Monitor Azure Files?

Monitoring Azure Files is crucial for several reasons:

  1. Performance Optimization: Monitoring can help you identify performance bottlenecks and optimize your file shares for better performance.
  2. Cost Management: By monitoring your usage, you can identify unnecessary costs and optimize your spending.
  3. Security and Compliance: Monitoring can help you detect unusual activity and ensure compliance with security policies and regulations.
  4. Troubleshooting: If issues arise, monitoring data can provide valuable insights to help troubleshoot and resolve these issues quickly.

Azure Monitor: Your Monitoring Tool

Azure Monitor is a service provided by Microsoft Azure for collecting, analyzing, and acting on telemetry from your cloud and on-premises environments. It helps you understand how your applications are performing and proactively identifies issues affecting them and the resources they depend on.

  3. Click on “+ Add diagnostic setting”.
  4. In the “Diagnostic setting name” field, enter a name for your diagnostic setting.
  5. Under “Log”, check the box for “AzureFileOperation”.
  6. Under “Destination details”, check the box for “Send to Log Analytics workspace” and select your Log Analytics workspace from the dropdown menu.
  7. Click on “Save” to save your diagnostic setting.

Step 3: Create Log Queries

Azure Monitor uses a query language known as Kusto Query Language (KQL) to retrieve and analyze data. You can create log queries to retrieve specific data from your Azure Files service.

  1. In the Azure Monitor service, click on “Logs”.
  2. In the query editor, you can write your KQL queries. For example, to retrieve all operations from your Azure Files service, you can use the following query:
  1. Click on “Run” to run your query and retrieve the data.

Azure Monitor allows you to set up alerts based on your log queries. This allows you to receive notifications when specific conditions are met.

  1. In the Azure Monitor service, click on “Alerts”.
  2. Click on “+ New alert rule”.
  3. Under “Scope”, select your storage account.
  4. Under “Condition”, click on “+ Add”.
  5. Select “Custom log search” and enter your KQL query.
  6. Specify the threshold value and period for your alert.
  7. Click on “Done” to add your condition.
  8. Under “Action group”, select or create an action group. This defines what actions should be taken when the alert is triggered.
  9. Under “Alert rule details”, enter a name and description for your alert rule.
  10. Click on “Create alert rule” to create your alert.


Monitoring Azure Files is crucial for optimizing performance, managing costs, ensuring security and compliance, and troubleshooting issues. By leveraging Azure Monitor, you can collect and analyze telemetry data from your Azure Files service and set up alerts to notify you of specific conditions.

Remember, monitoring is just one aspect of managing your Azure Files service. It’s also important to consider other aspects such as performance optimization, cost management, and security. By taking a holistic approach to managing your Azure Files service, you can ensure optimal performance and availability for your file shares.
