This telemetry includes metrics, logs, and activity logs. Metrics are numerical values measured over time, offering insights into resource performance (CPU utilization, memory usage, network traffic). Logs contain textual data about system events, errors, and application traces. Activity logs record administrative actions taken on Azure resources (creating VMs, updating configurations).
Azure Monitor provides a single pane of glass for observing the health and performance of your applications and infrastructure. You can visualize data through dashboards, notebooks, and workbooks, allowing for quick identification of issues. Proactive alerting based on predefined or custom rules ensures timely notifications of critical events, enabling prompt remediation. You can set up alerts based on metric thresholds (e.g., high CPU usage), log patterns (e.g., specific error messages), or activity patterns (e.g., unauthorized access attempts).
Beyond monitoring, Azure Monitor facilitates diagnostics by providing tools to drill down into issues, analyze root causes, and optimize performance. Log Analytics, a key feature, allows you to query and analyze log data using a powerful query language. Application Insights provides deep observability into your applications, tracking requests, dependencies, and exceptions. Azure Monitor integrates with other Azure services, like Azure Automation and Azure Logic Apps, to automate responses to incidents and streamline operations. Essentially, it empowers you to understand the state of your IT estate, identify problems quickly, and ensure optimal performance and availability.
Azure Monitor: A Comprehensive Guide
{'importance': "**_Why is Azure Monitor Important?_** Azure Monitor is crucial for maintaining the health, performance, and availability of your Azure resources and applications. Without proper monitoring, you're essentially flying blind, unable to proactively identify and resolve issues, optimize resource utilization, or ensure a positive user experience. It enables informed decision-making and efficient resource management, leading to cost savings and improved service reliability.", 'exam_tips_az900': "**_Exam Tips: Answering Questions on Azure Monitor (AZ-900)_** br Here's how to tackle Azure Monitor related questions in the AZ-900 exam: br br *__Understand Core Concepts:__* Focus on the fundamental concepts: metrics, logs, alerts, and dashboards. Know the differences between them and their respective use cases. br *__Know the Benefits:__* Emphasize the business benefits of Azure Monitor, such as improved uptime, reduced costs, and enhanced security. Think in terms of *proactive* monitoring versus *reactive* troubleshooting.br *__Differentiate from other services:__* Be able to differentiate Azure Monitor from other services, such as Azure Advisor (which provides recommendations) or Azure Security Center (which focuses on security). Azure Monitor is *generic* telemetry and monitoring.br *__Focus on capabilities described in this guide:__* Metrics/Logs/Alerts, that is all you need to know for AZ-900! br *__Practice Questions:__* Practice with mock exams to get comfortable with the question format and identify your weak areas. Focus particularity on the type of data collected by Azure Monitor.", 'example_questions': '**_Example AZ-900 Questions and how to answer them: _** br br *__Question:__* Which Azure service provides a centralized platform for collecting and analyzing telemetry data from various sources? br *__Answer:__* Correct answer will be Azure Monitor, because none others allow collecting and analysis of metrics and logs.br br *__Question:__* Which type of data is collected by Azure Monitor to track the performance of your resources over time? br *__Answer:__* Correct answer will be metrics, because metrics are the only numerical values that relates to performance over time', 'what_is_azure_monitor': '**_What is Azure Monitor?_** Azure Monitor is a comprehensive monitoring service in Azure that collects, analyzes, and acts on telemetry data from your cloud and on-premises environments. It provides a single platform for monitoring all your resources, including VMs, applications, networks, and operating systems. Azure Monitor helps you understand the performance and health of your infrastructure and applications so you can identify issues and resolve them quickly.', 'how_azure_monitor_works': "**_How Azure Monitor Works?_** Azure Monitor works by collecting telemetry data from various sources: br br *__Metrics:__* Numerical values that describe the performance of your resources over time (e.g., CPU utilization, memory usage, network traffic). br *__Logs:__* Text-based records of events and activities that occur within your environment (e.g., application errors, security events, audit logs). br br This data is collected through agents (for VMs and on-premises servers), diagnostic settings (for Azure resources), and APIs. The collected data is then stored in Azure Monitor's data platform, optimized for time-series data. You can then use Azure Monitor's tools and features to analyze the data, create alerts, visualize trends, and diagnose issues.Key components include Log Analytics Workspace (for log data), Azure Monitor Metrics (for metric data), and Action Groups (for automated responses)."}
