Azure Monitor and Azure Application Insights are two powerful services provided by Microsoft Azure for monitoring and analyzing applications and infrastructure. While they share some similarities, each service is designed to address specific monitoring needs. In this article, we'll delve into the differences between Azure Monitor and Azure Application Insights, highlighting their features, capabilities, and ideal use cases.
Overview of Azure Monitor
Azure Monitor is a comprehensive monitoring service that collects, analyzes, and acts on telemetry data from your cloud and on-premises environments. It provides a unified solution for monitoring the performance and availability of your resources, from infrastructure to applications.
Overview of Azure application insights
Azure Application Insights is a feature of Azure Monitor specifically designed for monitoring the performance, availability, and usage of web applications. It provides deep insights into application behavior and helps diagnose issues to improve overall application performance.
