Custom data sources - Amazon CloudWatch
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Custom data sources

For logs that are not covered by Amazon 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

For more details, see Custom log data from CloudWatch Logs or an Amazon S3 bucket.
