## Summary of Azure Event Grid System Topic discovery with Patterns

This document explains how to discover and map Azure Event Grid System Topics in your cloud environment using ServiceNow Discovery and Service Mapping Patterns.
It highlights prerequisites, configuration steps, and how data is populated in both CMDB and non-CMDB tables.
This enables customers to maintain accurate and up-to-date records of their Azure Event Grid System Topics within ServiceNow.

## Key Features

* **Pattern-based discovery:** Utilizes specific Azure patterns to identify and map Event Grid System Topics and related resources.
* **Permissions and prerequisites:** Requires verifying REST API permissions and ensuring Microsoft Azure discovery prerequisites are met. A Cloud Discovery patterns spreadsheet provides detailed pattern names, permissions, and CI classes.
* **Resource Inclusion List management:** Advises removing resources from the Resource Inclusion List table to prevent duplicate discoveries.
* **Pattern activation:** Patterns like the Azure Event Grid System Topic are disabled by default but can be enabled without affecting updates or customizations starting from Visibility Content version 6.28.0.
* **Discovery schedule configuration:** Supports Azure GovCloud discovery by configuring service accounts with specific datacenter URLs.
* **Data storage:** Populates relevant Azure Event Grid System Topic data in both CMDB and non-CMDB tables, including detailed fields and relationships.
* **Tag discovery:** Collects Azure resource tags and stores them in the Key Value table for enhanced resource metadata management.

## Data and CI Relationships

The discovery pattern populates:

* **Non-CMDB data:** Information such as kind, metric resource ID, provisioning state, subscription, tenant ID, and topic type is stored in the `cmdbazureeventgridsystemtopic` table.
* **CMDB data:** Key details like install status, location, operational status, and type (set to `microsoft.eventgrid/systemtopics`) are stored in the `cmdbcicloudmessagingservice` table.
* **CI Relationships:** Establishes relationships linking Event Grid System Topics to resource groups, cloud messaging services, and Azure datacenters, supporting comprehensive discovery and service mapping.
* **Tag metadata:** Tags discovered on Azure resources are stored in the `cmdbkeyvalue` table, capturing tag names and values for better asset management.

## Practical Benefits for ServiceNow Customers

* Enables automated, accurate discovery and mapping of Azure Event Grid System Topics in ServiceNow CMDB.
* Supports compliance and operational visibility by maintaining up-to-date resource inventories and relationships.
* Facilitates governance and reporting by capturing detailed resource properties and tags.
* Integrates seamlessly with Azure GovCloud environments through configurable discovery schedules.
* Reduces discovery errors by managing resource inclusion lists and ensuring proper permissions.  
Discovery and Service Mapping Patterns finds Azure services 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 {#azure-event-grid-pattern__section_ipy_53n_jfc}

Verify the REST API permissions
:   Download the [Cloud Discovery patterns spreadsheet](https://downloads.docs.servicenow.com/resource/enus/api/servicenow-discovery-patterns-api-details.xlsx) so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.{#azure-event-grid-pattern__cloud-discovery-api-ph-short-prereq}

Verify the Microsoft Azure discovery prerequisites{#azure-event-grid-pattern__verify-azure-discovery-prerequisites-dlentry}
:   For more information, see the prerequisites section in [Microsoft Azure Cloud discovery using patterns](https://www.servicenow.com/docs/e2521~KHAw8EO7j1nC9QMA "Discovery uses multiple patterns to discover components of the Microsoft Azure 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{#azure-event-grid-pattern__remove-resource-inclusion-list-azure}
:   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 [Microsoft Azure resource inventory discovery](https://www.servicenow.com/docs/tO3nNqXv4zOe7q99krvAnA "The ServiceNow Discovery application uses the Azure Resource Inventory (LP) pattern to find resources available through Azure that don’t have a dedicated pattern. 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{#azure-event-grid-pattern__enable-pattern-reuse-dlentry}
:   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.").{#azure-event-grid-pattern__activating-disabled-pattern-not-customization}

Configure the Discovery schedule to support GovCloud{#azure-event-grid-pattern__configure-govcloud-azure-dlentry}
:   Discovering Azure GovCloud (US) accounts requires using a datacenter URL when setting up an Azure service account. For more information, see [Set up Azure service accounts](https://www.servicenow.com/docs/XKQpJvxWTKNL58XCkRHVxA "Create and configure cloud service accounts at ServiceNow AI Platform for the corresponding Microsoft Azure accounts.").{#azure-event-grid-pattern__configure-govcloud-azure-dd}
{#azure-event-grid-pattern__configure-govcloud-azure-dd} Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

## Data stored in non-CMDB tables {#azure-event-grid-pattern__section_aq4_qkq_hfc}

Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Azure - Event Grid System Topic - Extended Inventory(LP) pattern.

You can review the non-CMDB
Azure tables by navigating to AllConfigurationAzure. You can also search the navigation filter for the specific pattern name.
