# Summary Analyzing Metrics

> This lesson explores performance metrics and monitoring tools in Azure for effective DevOps workflows and AZ-400 certification preparation.

In this lesson, we explore essential performance metrics and monitoring tools in Azure. Mastering these concepts is critical for the AZ-400 certification and for building robust, scalable cloud architectures. You’ll learn how to collect telemetry data, configure alerts, and create custom dashboards to streamline DevOps workflows.

## Key Performance Metrics

| Metric Category    | Metrics                          | Why It Matters                                       |
| ------------------ | -------------------------------- | ---------------------------------------------------- |
| CPU Performance    | CPU usage, CPU load              | Identifies processing bottlenecks and scaling needs. |
| Memory Utilization | RAM consumption, memory pressure | Ensures application responsiveness and stability.    |
| Disk Performance   | IOPS, throughput, latency        | Measures storage efficiency and data access speed.   |

  ![The image is a slide titled "Analyzing Metrics by Using Collected Telemetry, Including Usage and Application Performance," listing topics related to Azure telemetry and monitoring services. It includes a color-coded list of five topics, such as "Introduction to Telemetry in Azure" and "Monitoring Application Performance."](https://kodekloud.com/kk-media/image/upload/v1752867322/notes-assets/images/AZ-400-Designing-and-Implementing-Microsoft-DevOps-Solutions-Summary-Analyzing-Metrics/analyzing-metrics-azure-telemetry-slide.jpg)
</Frame>

Below are the key steps for leveraging telemetry in Azure:

1. **Introduction to Telemetry in Azure**\
   Collect performance and usage data from applications and infrastructure using Azure Monitor agents and SDKs.

2. **Analyzing Usage Metrics**\
   Use built-in reports and queries in Log Analytics to understand service consumption patterns and optimize resource allocation.

3. **Monitoring Application Performance**\
   Integrate Application Insights SDK into your codebase for end-to-end transaction tracking and real-time root-cause analysis.

4. **Configuring Alerts and Notifications**\
   Define alert rules in Azure Monitor based on metric thresholds or log query results to receive proactive notifications.

5. **Creating Custom Dashboards**\
   Build interactive dashboards in the Azure portal to visualize the most critical metrics, charts, and logs in one place.

## Best Practices for Azure Telemetry

* Define clear, actionable alert thresholds to minimize false positives.
* Encrypt telemetry data both in transit and at rest to ensure compliance.
* Automate the provisioning of monitoring resources using Infrastructure as Code (IaC).
* Regularly review and refine dashboards and alert rules as application workloads evolve.

  Over-alerting can lead to alert fatigue. Ensure each notification delivers actionable insights.
