AWS eventbridge: Update EventBridge monitoring docs for Classic vs Custom Event Bus

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

File: eventbridge/latest/userguide/eb-monitoring.md · Type: logging

Summary

Removes a CloudWatch Events evolution link, adds a pointer to Custom Event Bus observability (AWS/EventsV2 metrics and CloudWatch vended logs), and renames 'custom event bus' references to 'Custom Event Bus - Classic'.

Security assessment

The change is a terminology/scope update to monitoring documentation and only cross-references observability (metrics, logs, CloudTrail) for the new bus type; it documents no new security control or fix.

Evidence

+This section describes Custom Event Bus - Classic. For the Custom Event Bus, which publishes its metrics in the `AWS/EventsV2` namespace and its subscriber logs through CloudWatch vended logs, see [Observability for the Custom Event Bus: metrics, logs, and CloudTrail](./eb-custom-bus-observability.html).
