## Summary of Amazon EventBridge Event Bus pattern-based discovery

The Amazon EventBridge Event Bus pattern-based discovery within ServiceNow's Discovery and Service Mapping Patterns application identifies and maps EventBridge Event Buses in your AWS cloud environment.
This enables automatic population of both CMDB and non-CMDB tables with detailed configuration and relationship data about your EventBridge Event Buses.

## Prerequisites and Setup

* **AWS Discovery Prerequisites:** Ensure AWS discovery prerequisites are met, as detailed in the AWS discovery using patterns documentation.
* **Resource Inclusion List:** Remove relevant EventBridge Event Bus resources from the Resource Inclusion List \[sacloudinventoryresourcewhitelist\] to prevent duplicate discoveries.
* **Pattern Activation:** The EventBridge Event Bus discovery pattern is disabled by default and must be enabled. Starting with Visibility Content version 6.28.0, pattern activation changes are preserved during upgrades.
* **GovCloud Support:** For AWS GovCloud (US) accounts, configure the discovery schedule with the appropriate datacenter URL when creating AWS service accounts.

## Data Population and Tables

The discovery process populates data in both non-CMDB and CMDB tables:

* **Non-CMDB Data:** The Amazon AWS - EventBridge Event Bus - Extended Inventory (LP) pattern populates non-CMDB AWS tables accessible via *All \> Configuration \> AWS*. Key fields include the event bus name, ARN, and resource-based policy.
* **CMDB Data:** The same pattern populates the Cloud Messaging Service \[cmdbcicloudmessagingservice\] table in the CMDB with fields such as event bus name, ARN, resource type (AWS::EventBridge::EventBus), install status, and operational status.

## Configuration Item Relationships and References

The pattern creates relationships to represent hosting and references between CIs to provide a complete discovery picture:

* **CI Relationships:** Cloud Messaging Service CIs are linked as hosted on AWS Datacenter CIs.
* **CI References:** EventBridge Event Bus records reference the corresponding Cloud Messaging Service CI in their configuration item field.

## Tag Discovery

The pattern collects AWS tags associated with EventBridge Event Buses and stores them in the Key Value \[cmdbkeyvalue\] table. Each tag entry includes the tag name, value, and references the related Cloud Messaging Service CI.

## Practical Benefits for ServiceNow Customers

By enabling this pattern-based discovery, customers can automatically identify and track Amazon EventBridge Event Buses within their AWS environments, maintain accurate and up-to-date CMDB records, understand resource relationships, and leverage tagging information for better resource management and governance.  
Discovery and Service Mapping Patterns finds Amazon EventBridge Event Buses on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Pattern-based discovery and mapping requirements {#aws-eventbridge-event-bus__section_rpj_fj2_bgc}

Verify the AWS discovery prerequisites
:   For more information, see the prerequisites section in [AWS discovery using patterns](https://www.servicenow.com/docs/NFaTlkGaSxMWb2bQPsCnCA "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

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](https://www.servicenow.com/docs/0pDNq0441mpy~sExfQvvqA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

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](https://www.servicenow.com/docs/aypCYVQdO8oFebLMLEI89g "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#aws-eventbridge-event-bus__activating-disabled-pattern-not-customization}

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](https://www.servicenow.com/docs/vpueuFRHMWLNi6dzsJv94A "Create AWS service accounts on the ServiceNow AI Platform to access your AWS account during AWS discovery.").
Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

## Data stored in non-CMDB tables {#aws-eventbridge-event-bus__section_aq4_qkq_hfc}

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 AllConfigurationAWS. You can also search the navigation filter for the specific pattern name.  
{#aws-eventbridge-event-bus__table_non_cmdb__entry__2}

| Field | Description |
|-|-|
| Name \[name\] | Name of the event bus. |
| Object ID \[object_id\] | The Amazon Resource Name (ARN) of the event bus. |
| Policy \[policy\] | The resource-based policy that controls who can send events to the event bus. |
| Configuration Item \[configuration_item\] | References the Cloud Messaging Service \[cmdb_ci_cloud_messaging_service\] table. |
[Table 1. AWS EventBridge Event Bus \[cmdb_aws_eventbridge_event_bus\]]
