AWS SDK v2.7.15 or greater (if using captureAWS or captureAWSClient) Express 4.14.0 or greater (if using Express and the associated X-Ray middleware) MySQL 2.12.0 or greater or greater (if using captureMySQL) Postgres 6.1.0 or greater (if using capturePostgres)
The AWS X-Ray SDK automatically records information for incoming and outgoing requests and responses (via middleware), as well as local data such as function calls, time, variables (via metadata and annotations), even EC2 instance data (via plugins).
Although the AWS X-Ray SDK was originally intended to capture request/response data on a web app, the SDK provides functionality for use cases outside this as well. The SDK exposes the 'Segment' and 'Subsegment' objects to create your own capturing mechanisms, middleware, etc.
This package includes all other AWS X-Ray packages.
