During the application monitoring process on AWS, we will use a suite of powerful Amazon CloudWatch tools to collect and analyze operational data. CloudWatch Logs allows you to record logs from services like API Gateway, supporting debugging and error tracing. CloudWatch Metrics helps track performance indicators such as latency, request count, and error rates. Based on these metrics, we can set up Alarms to automatically detect incidents and trigger alerts through Amazon SNS to email or other services. In addition, CloudWatch Log Insights offers a powerful query tool to analyze logs in an intuitive and efficient way. Finally, we will use CloudWatch Dashboards to create visual dashboards that centralize all metrics, logs, and alert charts, making it easier to monitor the overall system activity in real time.
