What topics are covered in module 9 regarding Amazon CloudWatch for monitoring various services?

Amazon CloudWatch is a monitoring service that collects metrics, logs, and events from AWS resources and applications. In module 9 we cover how to set up CloudWatch metrics for services such as EC2, RDS, Lambda, and custom applications. We also discuss creating dashboards to visualize key performance indicators, configuring alarms to trigger notifications or automated actions, and using CloudWatch Logs Insights for ad‑hoc log analysis. Additionally, we explore integration with CloudWatch Events (now EventBridge) to react to state changes, and best practices for naming conventions, retention policies, and cost optimization. By the end of the module, you should be able to design a comprehensive monitoring strategy that provides real‑time visibility into the health and performance of your cloud infrastructure. You’ll learn how to aggregate metrics across accounts using CloudWatch cross‑account dashboards, how to set up composite alarms for complex conditions, and how to use metric math to derive custom metrics. Finally, we cover how to export CloudWatch data to S3 or Kinesis for long‑term analytics and compliance reporting.
