About this Hands-on Lab

Welcome to this AWS hands-on lab for Using CloudWatch for Resource Monitoring!

This lab provides practical experience with creating and configuring multiple custom AWS CloudWatch dashboards and widgets.

The primary focus will be on the following features within CloudWatch:

1. CloudWatch Dashboards
1. Dashboard Widgets
1. CloudWatch Metrics

CloudWatch Dashboards built with custom widgets allow you to visually monitor resources and proactively take actions if needed. Overall, the dashboards give you a central (and visual) view of how your monitored resources are behaving at specific points in time.
