CloudWatch Logs for Lambda
Lambda auto-reports metrics to CloudWatch.
After permissions are set, Lambda logs all requests and stores code-generated logs in CloudWatch Logs.
Log group:
/aws/lambda/<function-name>View via Lambda console, CloudWatch console, AWS CLI, or CloudWatch API.
Lambda + X-Ray
X-Ray visualizes app components, bottlenecks, and error traces.
Lambda sends trace data when X-Ray tracing is enabled upstream (API Gateway, EC2 with X-Ray SDK).
Upstream service samples requests and passes a tracing header.
