Amazon EventBridge Event Bus pattern-based discovery

Discovery and Service Mapping Patterns finds Amazon EventBridge Event Buses on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Pattern-based discovery and mapping requirements

Verify the AWS discovery prerequisites

For more information, see the prerequisites section in AWS discovery using patterns.

Remove resources from the Resource Inclusion List table

Verify that the relevant resource isn't listed in the Resource Inclusion List [sa_cloud_inventory_resource_whitelist] table to avoid duplicate discovery. For more information on removing resources from the Resource Inclusion List, see AWS Resource Inventory discovery with Patterns.

Enable the relevant pattern

The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see Activate a disabled pattern.

Configure the Discovery schedule to support GovCloud

Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see Create AWS service accounts.

Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

Data stored in non-CMDB tables

Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - EventBridge Event Bus - Extended Inventory (LP) pattern.

You can review the non-CMDB AWS tables by navigating to All > Configuration > AWS. You can also search the navigation filter for the specific pattern name.
