AWS Step Functions can emit execution-level logs — state transitions, input and output payloads, errors, and per-state durations — to CloudWatch Log Groups. State machines also publish status-change events to EventBridge. CloudWatch Log Forwarder — enable logging on each state machine with a destination Log Group, and the Bronto forwarder Lambda subscribes to it.

Alternatives

  • EventBridge API Destinations — for execution status-change events (started, succeeded, failed, timed out) when full step-by-step detail isn’t required.
See Ingesting AWS Data into Bronto for the full service-to-method mapping.
