📖 What is Azure Monitor?
Azure Monitor collects and analyzes telemetry from Azure resources and applications. It provides a comprehensive view of performance, availability, and potential issues through logs, metrics, and alerts. This data enables proactive identification and resolution of problems, ensuring optimal system operation and user experience.
"Understand the distinction between Logs, Metrics, and Alerts within Azure Monitor. Exam questions frequently involve scenarios requiring appropriate monitoring solutions for specific resource types. Focus on Log Analytics Workspaces as a central repository for log data."

🔑 What are the Key Concepts of Azure Monitor?
- ▸ Metrics provide numerical values tracking resource performance over time, like CPU utilization or network bandwidth, and are optimized for charting.
- ▸ Logs contain detailed textual records of events occurring within Azure resources, useful for troubleshooting and auditing.
- ▸ Alerts are triggered by defined rules based on metrics or logs, notifying you of potential issues requiring attention.
- ▸ Log Analytics Workspaces are central repositories for collecting, searching, and analyzing log data from various sources.
- ▸ Azure Monitor integrates with other Azure services, enabling end-to-end monitoring of complex applications and infrastructure.

A scenario might describe a need to troubleshoot an application error – expect questions about using Azure Monitor logs to pinpoint the root cause.
Expect questions about choosing the correct Azure Monitor component to track the performance of a virtual machine, focusing on CPU usage and memory consumption.
❓ Frequently Asked Questions
When should I use Metrics versus Logs?
Use Metrics for performance monitoring and trending. Use Logs for detailed event information, troubleshooting, and auditing. They serve different purposes and complement each other.
What is the role of Log Analytics queries?
Log Analytics queries (using Kusto Query Language - KQL) allow you to search, filter, and analyze the data stored in Log Analytics Workspaces, enabling you to extract valuable insights.
Can Azure Monitor monitor on-premises resources?
Yes, using Azure Monitor agents, you can collect data from on-premises servers and send it to Azure for centralized monitoring and analysis, creating a hybrid monitoring solution.
