Analyze Log Data with CloudWatch Logs Insights

CloudWatch Logs Insights enables you to interactively search and analyze your log data in Amazon CloudWatch Logs. You can perform queries to help you quickly and effectively respond to operational issues. If an issue occurs, you can use CloudWatch Logs Insights to identify potential causes and validate deployed fixes.

CloudWatch Logs Insights includes a purpose-built query language with a few simple but powerful commands. CloudWatch Logs Insights provides sample queries, command descriptions, query autocompletion, and log field discovery to help you get started quickly. Sample queries are included for several types of AWS service logs.

CloudWatch Logs Insights automatically discovers fields in logs from AWS services such as Amazon Route 53, AWS Lambda, AWS CloudTrail, and Amazon VPC, and any application or custom log that emits log events as JSON.

You can use CloudWatch Logs Insights to search log data that was sent to CloudWatch Logs on November 5, 2018 or later.
