Introduction

This action disables an EventBridge rule on its event bus for the duration of the experiment. Matching events stop being delivered to the rule's targets while the rule is disabled.

The rule is re-enabled on stop. No rule configuration is removed or recreated.

Use Cases

• Simulate dropped or missed events for a downstream consumer (Lambda, ECS task, Step Functions, ...).
• Verify that a critical scheduled rule (cron-style) firing a routine job continues to work after a temporary outage.
• Test alerting / SLO breach detection when an expected event stream stops.

Rollback

The rule is automatically re-enabled when the experiment stops.

The pre-attack state (whether the rule was originally ENABLED or DISABLED) is recorded during Prepare and restored on Stop: a rule that was already disabled remains disabled.

Parameters

Parameter	Description	Default
Duration	How long to keep the rule disabled. Re-enabled on stop.	60s
