Turning on default rules
Integrated Setup automatically configures the following default rules in Amazon EventBridge. These rules create OpsItems in AWS Systems Manager OpsCenter. If you don't want EventBridge to create OpsItems for the following events, then clear this option in Integrated Setup. If you prefer, you can specify OpsCenter as the target of specific EventBridge events. For more information, see Configure EventBridge rules to create OpsItems. You can also turn off the default rules at any time on the Settings page.
Important
You can't edit the Category and Severity values for default rules but you can edit these values on OpsItems created from the default rules.
