    Summary of Azure Event Hub Namespace pattern-based discovery

    The Azure Event Hub Namespace pattern-based discovery is part of the Discovery and Service Mapping Patterns application in ServiceNow. It identifies Azure Event Hub Namespace resources in your Azure cloud environment and populates detailed information about these resources into both CMDB and non-CMDB tables. This enables comprehensive visibility and management of your Azure Event Hub resources within ServiceNow.

    Key Features

    • Pattern Activation: The Azure Event Hub Namespace discovery pattern is disabled by default. Starting with Visibility Content version 6.28.0, enabling or disabling patterns does not count as customization, allowing safe upgrades without losing settings.
    • Support for Azure GovCloud: Discovery supports Azure GovCloud (US) accounts, requiring configuration of the datacenter URL when setting up Azure service accounts.
    • Data Population in Tables:
      • Non-CMDB Table: The cmdbazureeventhubnamespace table stores detailed resource attributes such as kind, location, TLS version, provisioning state, network access, resource group, subscription ID, tenant ID, and references to related CIs.
      • CMDB Table: The pattern also populates the cmdbcicloudmessagingservice table with key resource details like install status, location, name, object ID, operational status, and resource type (fixed to microsoft.eventhub/namespaces).
      • Tag Discovery: Azure tags are collected and stored in the cmdbkeyvalue table, allowing tagging metadata to be managed and queried.
    • CI Relationships: The pattern establishes relationships among configuration items (CIs), linking the Event Hub Namespace to resource groups, cloud messaging services, and Azure datacenters for accurate service mapping.

    Practical Considerations for ServiceNow Customers

    • Ensure you meet Microsoft Azure discovery prerequisites and have the appropriate service accounts configured, especially when working with Azure GovCloud environments.
    • Activate the Azure Event Hub Namespace pattern in your Discovery and Service Mapping Patterns application to enable discovery; this activation is safe across upgrades.
    • Review discovered data in both CMDB and non-CMDB tables to gain full visibility into your Azure Event Hub resources and their configurations.
    • Utilize CI relationships and tag data to enhance your CMDB accuracy and support effective service mapping and resource management.

    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 - 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.
