    Summary of Azure Service Bus Topic pattern-based discovery

    Azure Service Bus Topic pattern-based discovery enables ServiceNow customers to automatically find and map Azure Service Bus Topics within their cloud environment using the Discovery and Service Mapping Patterns application. This pattern helps populate detailed topic data into both CMDB and non-CMDB tables, supporting accurate configuration management and operational visibility.

    Key Features

    • Pattern Activation: The Azure Service Bus Topic discovery pattern is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating patterns is not considered a customization and patterns reset to the latest version after upgrades, preserving the last active state.
    • Prerequisites: Microsoft Azure discovery prerequisites must be met before enabling the pattern. Additionally, discovery schedules need configuration to support Azure GovCloud environments by using specific datacenter URLs.
    • Data Population:
      • Non-CMDB tables: The pattern populates extended inventory data, such as topic configuration details, in non-CMDB Azure-specific tables accessible under All > Configuration > Azure.
      • CMDB tables: Core topic information is stored in the Cloud Topic [cmdbcicloudtopic] table for integration with ServiceNow CMDB and relationship mapping.
    • Configuration Item (CI) Relationships: The pattern automatically creates relationships to represent containment and hosting, connecting Cloud Topics to Resource Groups, Azure Datacenters, and other cloud resources for a comprehensive service map.

    Key Outcomes

    • Accurate discovery and inventory of Azure Service Bus Topics, including operational and configuration details such as partitioning, message size limits, subscription counts, and status.
    • Enhanced visibility of Azure Service Bus Topics within the ServiceNow CMDB, supporting better governance, impact analysis, and change management.
    • Support for Azure GovCloud discovery by configuring appropriate service accounts and schedules, ensuring compliance and coverage for US government cloud environments.
    • Continuous updates to discovery patterns without customization conflicts, ensuring customers benefit from the latest improvements and fixes.

    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 components 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 - Service Bus Topic - 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 Service Bus - Topic [cmdb_azure_service_bus_topic]
    Field Description
    Enable Batched Operations [enable_batched_operations] Indicates whether batched operations are enabled for the topic.
    Enable Partitioning [enable_partitioning] Specifies if the topic is partitioned to support scalability.
    DC Location [location] The geographical region where the topic is deployed.
    Max Message Size In KB [max_message_size_in_kb] The maximum size of any message that can be sent to the topic, measured in kilobytes (KB).
    Max Size In MB [max_size_in_mb] The maximum storage limit for the topic in megabytes (MB).
    Object Id [object_id] The unique identifier for the topic resource.
    Status [status] The status of the topic resource. For example: Active or Disabled.
    Subscription Count [subscription_count] The number of active subscriptions associated with the topic.
    Resource Group [resource_group] Name of the resource group.
    Subscription ID [subscription_id] The subscription ID.
    Configuration Item [configuration_item] References the Cloud Topic [cmdb_ci_cloud_topic] table.

    Data stored in CMDB tables

    Discovery and Service Mapping Patterns application populates data in the CMDB when running the Azure - Service Bus Topic - Extended Inventory(LP) pattern.

    Table 2. Cloud Topic [cmdb_ci_cloud_topic]
    Field Description
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Location [location] The geographical region where the topic is deployed.
    Name [name] The name of the topic within the Service Bus namespace.
    Object ID [object_id] The unique identifier of the resource in the following format: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ServiceBus/namespaces/{namespaceName}/topics/{topicName}
    Operational status [operational_status] Operational status of the resource. Default value is Operational.
    Description [short_description] Description of the resource or service.

    CI relationships

    The pattern creates these relationships to support discovery.

    CI Relationship CI
    Cloud Resource [cmdb_ci_cmp_resource] Contains::Contained by Cloud Topic [cmdb_ci_cloud_topic]
    Resource Group [cmdb_ci_resource_group] Contains::Contained by Cloud Topic [cmdb_ci_cloud_topic]
    Cloud Topic [cmdb_ci_cloud_topic] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]
    Azure Service Bus - Topic [cmdb_azure_service_bus_topic] References Cloud Topic [cmdb_ci_cloud_topic]
