AWS Cloud Development Kit - From Beginner to Professional - CloudWatch Live Dashboards and Widgets

The video tutorial covers the creation and management of AWS CloudWatch dashboards and widgets. It explains the importance of consolidating metrics from various cloud resources like Lambda functions and EC2 instances into a single dashboard for better monitoring and action-taking. The tutorial walks through setting up a CDK stack, creating custom metrics and alarms, and building a dashboard with graph and single value widgets. It also demonstrates testing the dashboard and enabling dark mode for better visualization.

What is the primary purpose of using CloudWatch dashboards?
