This capability is part of the Discovery and Service Mapping Patterns application, designed to help you accurately populate your CMDB and non-CMDB tables with detailed Azure resource data. Show full answer Show less To use this feature effectively, ensure you have met Microsoft Azure discovery prerequisites and enabled the relevant pattern, which is disabled by default. From Visibility Content version 6.28.0 onward, enabling or disabling patterns does not count as customization, allowing automatic updates during upgrades. For Azure GovCloud (US) discoveries, configure your Azure service accounts with the appropriate datacenter URL to support discovery schedules. ## Key Features * **Pattern Activation:** Activate the Azure Compute Gallery Image Definition pattern to enable discovery; pattern activation status resets to predefined versions on upgrades but retains the last active state. * **Data Population:** The pattern populates Azure Compute Gallery Image Definition details into both CMDB and non-CMDB tables, ensuring comprehensive resource tracking. * **Non-CMDB Data Tables:** Key resource attributes such as architecture, Hyper-V generation, kind, location, OS type, provisioning state, resource group, SKU, subscription ID, and tenant ID are stored in the `cmdbazurecomputegalleryimagedefinition` table. * **CMDB Data Tables:** Core resource CMDB records are created in the `cmdbcicmpresource` table, including install status, location, name, object ID, operational status, and resource type. * **CI Relationships:** The pattern establishes relationships between the discovered Image Definition, resource groups, cloud resources, and Azure datacenters to maintain accurate dependency mapping. * **Tag Discovery:** Azure tags associated with resources are collected and stored in the `cmdbkeyvalue` table, facilitating better resource categorization and management. ## Practical Benefits for ServiceNow Customers * Gain detailed visibility into your Azure Compute Gallery Image Definitions, including their configurations, statuses, and locations across your subscriptions and tenants. * Maintain an accurate and up-to-date CMDB that reflects your Azure resources and their relationships, supporting better change, incident, and asset management. * Leverage automated pattern-based discovery to reduce manual data entry and improve the reliability of your cloud infrastructure data. * Support compliance and governance requirements by mapping and tracking resource tags and provisioning states. * Ensure compatibility with Azure GovCloud by correctly configuring discovery schedules and service accounts. 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 {#azure-compute-gallery-img-definition__section_ipy_53n_jfc} Verify the Microsoft Azure discovery prerequisites{#azure-compute-gallery-img-definition__verify-azure-discovery-prerequisites-dlentry} : For more information, see the prerequisites section in [Microsoft Azure Cloud components discovery using patterns](https://www.servicenow.com/docs/JeDZ0tlC9eLF5fei5qSv3w "Discovery uses multiple patterns to discover components of the Microsoft Azure Cloud deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Enable the relevant pattern{#azure-compute-gallery-img-definition__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/R5W5GP640V_5uNIhVNRPCw "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#azure-compute-gallery-img-definition__activating-disabled-pattern-not-customization} Configure the Discovery schedule to support GovCloud{#azure-compute-gallery-img-definition__configure-govcloud-azure-dlentry} : Discovering Azure GovCloud (US) accounts requires using a datacenter URL when setting up an Azure service account.
