    Summary of Azure Event Hub Namespace pattern-based discovery

    This discovery pattern enables ServiceNow customers to identify and map Azure Event Hub Namespace resources within their Microsoft Azure cloud environments. It is part of the Discovery and Service Mapping Patterns application and requires the latest version of this application for optimal functionality. The pattern uncovers detailed resource information and relationships, populating both CMDB and non-CMDB tables to provide a comprehensive view of Azure Event Hub Namespaces and their configurations.

    Key Features

    • Pattern Activation: The Azure Event Hub Namespace pattern is disabled by default. Starting with Visibility Content version 6.28.0, enabling or disabling patterns is no longer considered customization and patterns reset to the latest predefined version after upgrades while retaining activation status.
    • Discovery Prerequisites: Proper Microsoft Azure discovery prerequisites must be met, including configuring Azure service accounts, especially when working with Azure GovCloud (US), which requires a specific datacenter URL.
    • Data Population: The pattern populates resource data into both CMDB tables and non-CMDB tables:
      • Non-CMDB Tables: Contains detailed Azure Event Hub Namespace inventory data accessible via the Configuration > Azure section.
      • CMDB Tables: Populates the Cloud Messaging Service table with key attributes and maintains relationships to resource groups and Azure datacenters.
    • Resource Attributes Captured: Includes critical fields such as kind, location, minimum TLS version, object ID, provisioning state, public network access, resource group, subscription ID, tenant ID, install status, operational status, and type.
    • CI Relationships: Establishes relationships linking Azure Event Hub Namespace CIs to resource groups, cloud messaging services, and Azure datacenters to support comprehensive discovery and mapping.
    • Tag Discovery: Collects Azure tags associated with Event Hub Namespaces and stores them in the Key Value table, enabling better resource categorization and filtering.

    Practical Implications for ServiceNow Customers

    Enabling and running the Azure Event Hub Namespace discovery pattern allows customers to automate the identification and inventory of their Azure Event Hub Namespace resources within ServiceNow CMDB. This enriches asset visibility, supports compliance and security posture management (e.g., TLS versions and network access), and facilitates better cloud resource governance through tag capture and CI relationship mapping. Customers should ensure prerequisite configurations are met and the pattern is enabled to benefit from up-to-date, actionable data on their Azure Event Hub Namespaces.

    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 - Event Hub Namespace - 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 Event Hub - Namespace [cmdb_azure_event_hub_namespace]
    Field Description
    Kind [kind] The nature or subtype of the resource, often describing its specific role or variation.
    Location [location] The geographical location where the resource is hosted.
    Minimum TLS Version [minimum_tls_version] The minimum Transport Layer Security (TLS) version required by the resource for secure connections.
    Object Id [object_id] The unique identifier of the resource.
    Provisioning State [provisioning_state] The current status of the resource provisioning process.
    Public Network Аccess [public_network_access] Indicates whether the resource can be accessed via the public network.
    Resource Group [resource_group] Name of the resource group.
    Subscription ID [subscription_id] The subscription ID.
    Tenant ID [tenant_id] The identifier of the Azure Active Directory tenant.
    Configuration Item [configuration_item] References the Cloud Messaging Service [cmdb_ci_cloud_messaging_service] table.

    Data stored in CMDB tables

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

    Table 2. Cloud Messaging Service [cmdb_ci_cloud_messaging_service]
    Field Description
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Location [location] The geographical location where the resource is hosted.
    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.
    Type [type] Type of resource. The value is set to microsoft.eventhub/namespaces.

    CI relationships

    The pattern creates these relationships to support discovery.

    CI Relationship CI
    Resource Group [cmdb_ci_resource_group] Contains::Contained by Cloud Messaging Service [cmdb_ci_cloud_messaging_service]
    Cloud Messaging Service [cmdb_ci_cloud_messaging_service] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]
    Azure Event Hub - Namespace [cmdb_azure_event_hub_namespace] References Cloud Messaging Service [cmdb_ci_cloud_messaging_service]

    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.
