SAM function without active X-Ray tracing

Description

A SAM function’s Tracing: Active lets Lambda sample requests and initiate X-Ray tracing. Missing required trace data can make latency or cross-service problems harder to investigate.

Potential impact

Without another tracing mechanism, finding call paths and failure points can take longer.

Remediation

Set Tracing: Active when active tracing is needed. Grant X-Ray write permissions to any explicitly supplied execution role and instrument code for downstream calls that need tracing.

Examples

The examples enable active tracing for an image-based function. Set the image and execution configuration to suit the actual environment.
