Service: eventbridge · 2026-09-27 · Documentation low

File: eventbridge/latest/userguide/eb-related-service-xray.md

Summary

Adds a note scoping the page to Custom Event Bus - Classic and describing how a Custom Event Bus subscriber propagates trace headers to Step Functions and SQS targets; also renames a nav entry from 'Third-party integrations' to 'Monitoring'.

Security assessment

Purely informational tracing/observability documentation and a navigation label change; no security control, credential, or vulnerability content.

Evidence

This page applies to Custom Event Bus - Classic. A Custom Event Bus subscriber propagates a trace header to Step Functions targets through `StepFunctionsParameters.TraceHeader` and to Amazon SQS targets through `MessageSystemAttributes`; see [Targets for a Custom Event Bus subscriber](./eb-custom-bus-targets.html).
