Custom data sources

For logs that are not covered by AWS service or third-party integrations, CloudWatch pipelines can process custom logs stored in CloudWatch Logs or Amazon S3 buckets. Custom sources accommodate unique organizational requirements:

  • Application-specific logs – Custom application telemetry from Amazon EC2 instances with specialized logging formats

  • File-based ingestion – Amazon S3-based log files from legacy systems or batch processing workflows

  • Serverless integration – Lambda function logs and custom serverless application telemetry
