b) Automating infrastructure deployments with Azure Resource Manager (ARM) templates and Azure DevOps.
c) Monitoring applications deployed in Azure using Azure Monitor and integrating alerts with Azure DevOps.

Module 10: Azure Monitoring and Management


1. Azure Monitor for Logging and Monitoring
Azure Monitor is a comprehensive monitoring solution that provides insights into the performance and health of Azure resources. It collects telemetry data from various sources and offers features for logging, metrics collection, alerting, and dashboards.
(i) Logging with Azure Monitor
a) Logging: Capture and store log data generated by Azure resources, including virtual machines, databases, and applications.
b) Log Analytics: Analyze log data using powerful query language and tools provided by Azure Log Analytics.
(ii) Metrics Monitoring
a) Metrics: Collect and monitor performance metrics such as CPU usage, memory utilization, and network traffic for Azure resources.
b) Azure Metrics Explorer: Visualize and analyze metric data using built-in charts and graphs.

2. Azure Log Analytics and Azure Metrics
(i) Azure Log Analytics
Azure Log Analytics is a service that collects, analyzes, and visualizes log data from Azure resources and on-premises environments. It offers advanced querying capabilities, machine learning insights, and integration with other Azure services.
(ii) Azure Metrics
Azure Metrics provides a centralized location for monitoring performance metrics across Azure services. It offers built-in charts, alerts, and dashboards for visualizing and analyzing metric data in real-time.

3. Azure Alerts and Azure Automation
(i) Azure Alerts
Azure Alerts enable proactive monitoring and notification of resource states and conditions. Users can set up alerts based on metrics, logs, and activity logs, and define actions to take when alerts are triggered.
(ii) Azure Automation
Azure Automation allows users to automate manual, repetitive tasks and processes within Azure environments. It provides capabilities for creating runbooks, scheduling jobs, and integrating with other Azure services.

4. Application Insights for Application Performance Monitoring
Application Insights is a service that provides application performance monitoring (APM) and diagnostics for web applications. It offers features for monitoring availability, performance, and usage of applications, as well as diagnosing and troubleshooting issues.
Performance Monitoring:
a) Availability Monitoring: Monitor the availability and responsiveness of web applications from various locations.
b) Performance Metrics: Track performance metrics such as response times, page load times, and server-side exceptions.

5. Best Practices for Azure Monitoring and Management
(i) Define Monitoring Requirements: Identify key performance indicators (KPIs) and metrics to monitor based on business objectives and requirements.
(ii) Set up Alerts and Notifications: Configure alerts and notifications to proactively monitor resource states and conditions and take timely action.
(iii) Centralize Logging and Monitoring: Use Azure Monitor and Log Analytics to centralize logging and monitoring across Azure resources and environments.
(iv) Automate Remediation: Implement Azure Automation to automate remediation tasks and ensure timely response to alerts and incidents.
