    • Discovery and Service Mapping Patterns finds Azure OS images 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 overview

    Discovery uses the Azure - Image (LP) pattern to discover Azure OS images from your Azure account.

    When using the Image [cmdb_ci_os_template] table to store Cloud OS images, you may notice an unusually large number of records. To avoid this issue, you can store the discovered OS images in the Cloud Image [cmdb_ci_cloud_os_image] table. When enabled, Discovery launches the Azure - Cloud OS Image (LP) pattern, which populates the Cloud Image [cmdb_ci_cloud_os_image] table. For more information, see Enable Cloud OS Image discovery.

    Pattern-based discovery and mapping requirements

    Verify the Azure discovery prerequisites section in Microsoft Azure Cloud discovery using patterns.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Azure OS image patterns.

    표 1. Image [cmdb_ci_os_template] or Cloud Image [cmdb_ci_cloud_os_image]
    Field Description
    Name [name] Name of the image resource.
    Object ID [object_id] Azure resource ID of the image.
    Image Source [image_source] Azure resource ID of the image.

    Provider [provider] The cloud provider, which is AZURE.

    This field is only populated in Cloud Image [cmdb_ci_cloud_os_image] table.

    CI relationships

    The Azure OS image patterns create these relationships to support Azure OS image discovery.

    CI Relationship CI
    Image [cmdb_ci_os_template] or Cloud Image [cmdb_ci_cloud_os_image] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]
    Resource Group [cmdb_ci_resource_group] Contains::Contained by Image [cmdb_ci_os_template] or Cloud Image [cmdb_ci_cloud_os_image]
    Key Value [cmdb_key_value] References Image [cmdb_ci_os_template] or Cloud Image [cmdb_ci_cloud_os_image]

    Azure Tag discovery

    The Azure OS image patterns collect tags and populate them in the Key Value [cmdb_key_value] table.

    표 2. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
