    Summary of Azure Compute Gallery Image Definition Pattern-Based Discovery

    The Azure Compute Gallery Image Definition pattern-based discovery enables ServiceNow users to discover Azure services in their cloud environments. This process may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Key Features

    • Prerequisites: Ensure compliance with Microsoft Azure discovery prerequisites.
    • Pattern Activation: The relevant discovery pattern is disabled by default. Starting from Visibility Content version 6.28.0, activating or deactivating patterns will not be treated as customizations, allowing for continuous updates.
    • GovCloud Support: To discover Azure GovCloud accounts, use a datacenter URL when setting up the Azure service account.
    • Data Population: The application populates both CMDB and non-CMDB tables with data during the discovery process.

    Data Storage

    Data can be stored in both non-CMDB and CMDB tables, depending on the pattern being used:

    • Non-CMDB Tables: When running the Azure - Compute Gallery Image Definition - Extended Inventory(LP) pattern, data is stored in non-CMDB tables, accessible via the Azure configuration section.
    • CMDB Tables: The same pattern populates data in the CMDB, including essential fields like install status, operational status, and resource type.

    Key Outcomes

    By utilizing the Azure Compute Gallery Image Definition pattern, ServiceNow customers can effectively manage and track Azure resources, ensuring that data integrity is maintained across both CMDB and non-CMDB tables. This enables better resource management, operational visibility, and streamlined cloud service discovery.

    Discovery and Service Mapping Patterns finds Azure services 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 Microsoft Azure discovery prerequisites
    For more information, see the prerequisites section in Microsoft Azure Cloud discovery using 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 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.

    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 Azure - Compute Gallery Image Definition - Extended Inventory(LP) pattern.

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

    Table 1. Azure Compute Gallery - Image Definition [cmdb_azure_compute_gallery_image_definition]
    Field Description
    Architecture [architecture] Central processing unit (CPU) architecture of the resource, such as x86 or ARM.
    Hyper-V Generation [hyper_v_generation] The Hyper-V generation version of the virtual machine.
    Kind [kind] The specific subcategory or variation type of the resource.
    Location [location] The geographical region where the resource is deployed.
    Object Id [object_id] The unique identifier of the resource.
    OS Type [os_type] The operating system type associated with the resource.
    Provisioning State [provisioning_state] Current provisioning status of the resource.
    Resource Group [resource_group] Name of the resource group.
    SKU [sku] The stock keeping unit (SKU) that defines the pricing tier of the resource.
    Subscription ID [subscription_id] The subscription ID.
    Tenant ID [tenant_id] The unique identifier for the Azure Active Directory tenant.
    Configuration Item [configuration_item] References the Cloud Resource [cmdb_ci_cmp_resource] table.

    Data stored in CMDB tables

    Discovery and Service Mapping Patterns application populates data in the CMDB when running the Azure - Compute Gallery Image Definition - Extended Inventory(LP) pattern.

    Table 2. Cloud Resource [cmdb_ci_cmp_resource]
    Field Description
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Location [location] The geographical region where the resource is deployed.
    Name [name] The name given to the resource.
    Object ID [object_id] The unique identifier of the resource.
    Operational status [operational_status] Operational status of the resource. Default value is Operational.
    Resource type [resource_type] Type of resource. The value is set to microsoft.compute/galleries/images.

    CI relationships

    The pattern creates these relationships to support discovery.

    CI Relationship CI
    Resource Group [cmdb_ci_resource_group] Contains::Contained by Cloud Resource [cmdb_ci_cmp_resource]
    Cloud Resource [cmdb_ci_cmp_resource] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]
    Azure Compute Gallery - Image Definition [cmdb_azure_compute_gallery_image_definition] References Cloud Resource [cmdb_ci_cmp_resource]

    Azure tag discovery

    The pattern collects tags and populates them in the Key Value [cmdb_key_value] table.
    Table 3. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
