Amazon CloudWatch

Amazon CloudWatch is a native AWS monitoring and observability service built for DevOps engineers, developers, site reliability engineers (SREs), and IT managers. CloudWatch provides users with data and actionable insights to monitor applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. CloudWatch collects monitoring and operational data in the form of logs, metrics, and events, providing users with a unified view of AWS resources, applications, and services that run on AWS and on-premises servers. CloudWatch can be used to detect anomalous behavior in environments, set alarms, visualize logs and metrics side by side, take automated actions, troubleshoot issues, and discover insights to keep your applications running smoothly. With Amazon CloudWatch, there is no up-front commitment or minimum fee; users simply pay for what they use.
