Resource Overview​

Amazon CloudWatch Logs enables you to monitor, store, and access system, application, and custom log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS CloudTrail, Route 53, and other sources. CloudWatch Logs allows you to centralize logs from all systems, applications, and AWS services you use in a single, highly scalable service. You can then easily view logs, search for specific error codes or patterns, filter based on specific fields, or securely archive logs for future analysis. With CloudWatch Logs, you can view all logs as a single, consistent stream of events ordered by time regardless of source, query and sort them by different dimensions, group them by specific fields, create custom calculations using a powerful query language, and visualize log data.
