EventBridge Troubleshooting
Explore practical strategies for troubleshooting AWS EventBridge by identifying failure boundaries such as pattern mismatch, target invocation errors, and downstream execution issues. Understand how to verify event payloads against rule patterns, analyze evidence from EventBridge and targets, and apply minimal patterns to prevent brittle configurations. This lesson helps you confidently diagnose absence of expected executions and improve event-driven system reliability.
A remediation was supposed to run after a system event, but nothing happened, and that particular kind of failure is its own special headache. There's no stack trace, no error banner, no obvious place to start, just an absence where an execution should be. The report says an event from aws.health should have triggered a rule, and the target was a Step Functions state machine, yet there is no execution record and no obvious error in the application logs.
When the symptom is absence, speed comes from choosing a first check that splits the problem space cleanly into ...
