# Editing EventBridge rules created for Explorer
<a name="Explorer-using-editing-default-rules"></a>

When you complete Integrated Setup, the system allows more than a dozen rules in Amazon EventBridge. These rules automatically create OpsItems in AWS Systems Manager OpsCenter. AWS Systems Manager Explorer then displays aggregated information about the OpsItems.

Each rule includes a preset **Category** and **Severity** value. When the system creates OpsItems from an event, it automatically assigns the preset **Category** and **Severity**.

**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.

**To edit default rules for creating OpsItems**

1. Open the AWS Systems Manager console at [https://console.aws.amazon.com/systems-manager/](https://console.aws.amazon.com/systems-manager/).

1. In the navigation pane, choose **Explorer**.

1. Choose **Settings**.

1. In the **OpsItems rules** section, choose **Edit**.

1. Expand **CWE rules**.

1. Clear the check box beside those rules that you don't want to use.

1. Use the **Category** and **Severity** lists to change this information for a rule. 

1. Choose **Save**.

Your changes take effect the next time the system creates an OpsItem.
