    Summary of Azure Service Bus Topic pattern-based discovery

    The Azure Service Bus Topic pattern-based discovery in ServiceNow enables automated detection and mapping of Azure Service Bus Topic resources within your cloud environment. This capability is part of the Discovery and Service Mapping Patterns application, which helps populate both CMDB and non-CMDB tables with detailed information about these Azure resources. It requires enabling the specific pattern and meeting Azure discovery prerequisites to function correctly.

    Key Features

    • Pattern Activation: The Azure Service Bus Topic pattern is disabled by default; enabling it allows discovery of Service Bus Topic resources. Activating or deactivating patterns from Visibility Content version 6.28.0 onward does not count as customization and preserves update compatibility.
    • Discovery Support for Azure GovCloud: Special configuration using datacenter URLs is necessary to discover Azure GovCloud (US) accounts.
    • Data Population: The pattern populates data in both CMDB and non-CMDB tables, ensuring comprehensive resource representation.
    • Non-CMDB Table (cmdbazureservicebustopic): Stores detailed Azure Service Bus Topic attributes such as enablement of batched operations, partitioning, location, message size limits, topic status, subscription count, resource group, and subscription ID.
    • CMDB Table (cmdbcicloudtopic): Captures essential configuration item (CI) details including install status, location, name, unique object ID, operational status, and description.
    • CI Relationships: The discovery pattern establishes relationships between Cloud Topics, Resource Groups, Azure Datacenters, and other cloud resources to maintain an accurate and connected CMDB environment.

    Practical Application for ServiceNow Customers

    By enabling and configuring this pattern, ServiceNow customers can automatically discover and maintain up-to-date records of Azure Service Bus Topics in their CMDB. This facilitates better visibility, management, and operational insight into Azure messaging infrastructure. The accurate relationships and detailed attributes support impact analysis, compliance, and cloud resource governance. Additionally, proper setup for Azure GovCloud ensures coverage of US government cloud environments.

    Next Steps

    • Verify and complete Microsoft Azure discovery prerequisites before enabling the pattern.
    • Activate the Azure Service Bus Topic pattern within the Discovery and Service Mapping Patterns application.
    • Configure discovery schedules and Azure service accounts, especially if using Azure GovCloud.
    • Review discovered data in both CMDB and non-CMDB tables to validate accuracy and completeness.

    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]
