Azure Monitor & MELT: A Comprehensive Approach to Cloud Observability

Maintaining the performance and reliability of your applications and infrastructure is critical. Whether you’re a growing company, a large enterprise, or operating a hybrid environment, comprehensive observability is essential to ensuring your systems are running smoothly.

Azure Monitor, Microsoft’s fully managed observability platform, provides a powerful solution to help organizations achieve full stack observability across applications, infrastructure, and services. In this post, we’ll look at how Azure Monitor can help you do just that. fuze Framework(middleEtrix, Eventilation opening, LOgs, and teaIt provides deep insights, proactive monitoring, and automated problem resolution through a series of actionable workflows that illustrate how these concepts translate into efficient, automated operations.

Why MELT is important for cloud observations

Organizations of all sizes face the challenge of maintaining and scaling complex IT systems, where visibility into the health and performance of applications and infrastructure is critical. fuze The framework categorizes observability into four core pillars:

• Metric: Quantitative data showing resource and system performance, such as CPU, memory, and network usage.
• event: Notifications of important changes to your environment, such as expansions, resource updates, and system restarts.
• log: A detailed record of actions and errors that can be analyzed to troubleshoot problems and understand root causes.
• evidence: Helps you pinpoint performance bottlenecks by tracing requests through your distributed system end-to-end.

Together, these components provide a holistic view of your system, enabling you to proactively detect problems, optimize performance, and improve stability.

How Azure Monitor implements MELT

Azure Monitor is built to collect, analyze, and act on telemetry data across all MELT categories. It provides the visibility needed to maintain operational excellence at any scale, enabling organizations to prevent, detect, and resolve issues before they impact end users.

1. Metrics: Real-time performance insights

Azure Monitor automatically collects metrics from all your Azure resources, giving you real-time insights into CPU usage, memory consumption, and network traffic. Metrics Explorer lets you visualize this data over time, identify trends, and proactively troubleshoot performance issues.

For example, if your virtual machine’s CPU usage continues to spike, you can use Azure Monitor to set up alerts and trigger automated scaling actions to ensure optimal performance.

Here’s how to put the auto-scaling workflow into practice:

This workflow demonstrates how Azure Monitor automates scaling to optimize performance during high load conditions, and scales down when demand decreases.

2. Events: Tracking changes in the environment

Azure Activity Logs, part of Azure Monitor, captures important events in your environment, such as resource provisioning, scaling operations, or configuration updates. These events are essential for understanding changes and correlating them with performance fluctuations.

For example, if your application is experiencing delays after a new deployment, activity logs can help you quickly isolate potential causes of the problem by showing you exactly what changes were made and when they occurred.

3. Logs: In-depth analysis through Log Analytics

Logs provide detailed insights into operational events and errors, enabling thorough troubleshooting and root cause analysis. Azure Monitor Log Analysis You can query the logs using: Cousteau Query Language (KQL)This allows you to easily filter and aggregate large data sets.

A common scenario is to correlate logs with metrics to diagnose application issues. For example, if users report that a page is loading slowly, you can query the logs to identify slow database queries that correspond to backend errors or high CPU usage.

Here’s a workflow for detecting and resolving application errors using logs:

This workflow automatically detects recurring application errors and triggers actions such as service restarts to ensure minimal downtime and quick resolution.

4. Tracking: Monitoring Distributed Applications

In distributed systems and microservice architectures, evidence Essential for tracking request flows between services. Azure Monitor integrates with: Application InsightsSupports distributed tracing to monitor the performance and health of multi-service applications.

For example, if a customer request is taking too long to process, Application Insights can track that request across multiple services to help you identify which service is causing the delay or error.

Learn how distributed tracing can help you identify bottlenecks.

This workflow highlights how to use Application Insights to follow request flows, identify performance bottlenecks, and take actions to improve the responsiveness of your application.

Build an effective MELT strategy using Azure Monitor

To ensure your observability strategy is comprehensive and scalable, here’s how to leverage Azure Monitor’s MELT capability:

1. Centralized telemetry collection

Collect all telemetry (metrics, logs, events, and traces) from your applications and infrastructure into Azure Monitor. This centralization allows you to correlate data across the entire stack, providing a unified view of system health.

2. Actionable Notifications

Set up custom alerts that trigger when critical thresholds are reached. For example, you can set up alerts based on high CPU utilization, low memory availability, or specific error messages found in logs.

Examples of proactive security monitoring using logs include:

This workflow demonstrates how Azure Monitor can detect suspicious activity, such as repeated failed login attempts, and automatically trigger a security response to mitigate the threat.

3. Automation for scalability

Automating responses to alerts is critical to ensuring smooth operations. Azure Monitor integrates with Azure Automation and Logic Apps to trigger automated workflows, such as scaling resources during periods of high demand or restarting services when failures are detected.

4. Real-time dashboard and reporting

Create dashboards to visualize real-time metrics and logs, and integrate data with Power BI for deeper analysis. Dashboards give your team a live view of system performance, helping you proactively manage operations.

Below is a cost management workflow using metrics.

This workflow allows you to automatically scale down underutilized resources to reduce costs and maintain performance.
