Amazon CloudWatch: Monitoring and Observability Service for AWS Resources
A monitoring and observability service that delivers metrics, logs, and events to help developers and operators optimize applications, understand resource utilization, and get a unified view of operational health.
What is Amazon CloudWatch?
Amazon CloudWatch is a monitoring and management service that provides data and actionable insights for AWS resources and applications. CloudWatch delivers metrics, logs, and events to help developers, operations engineers, and IT managers understand how the components of their applications and infrastructure are performing so they can optimize for efficiency, availability, and reliability.
Some key capabilities and benefits of CloudWatch include:

- Logs - CloudWatch Logs enables you to monitor, store, and access your log files from AWS CloudTrail, Amazon EC2, and other sources.
- Events - CloudWatch Events delivers system events in real time so you can match events and route them to one or more event target functions.
- Dashboards - CloudWatch dashboards allow you to create customizable views of metrics and alarms to monitor your environment.
- Alarms - You can create alarms that trigger notifications or auto scaling actions based on thresholds you define on CloudWatch metrics.
- Integrations - CloudWatch integrates with various AWS services and allows you to easily monitor resources like instances, EBS volumes, Lambda functions and more.
Overall, CloudWatch gives developers and administrators visibility into resource utilization, operational health, application performance, and more - making it an essential monitoring tool on AWS.
