    Summary of Azure DNS zones and record sets discovery using Patterns

    The Discovery and Service Mapping Patterns application in ServiceNow enables the discovery of Azure Domain Name System (DNS) definitions, specifically DNS zones and their associated record sets, through the Azure - DNS Zones (LP) and Azure - DNS Zone Recordsets (LP) Patterns. Customers need to update the Discovery and Service Mapping Patterns application from the ServiceNow Store to access these features.

    Key Features

    • Discovery Patterns: Utilizes specific patterns to identify Azure DNS zones and record sets.
    • Data Collection: Automatically populates the Configuration Management Database (CMDB) with relevant data during discovery.
    • CI Relationships: Establishes relationships between discovered resources for better management and visibility.
    • Permissions Management: Requires specific API Management Service Reader role and REST API permissions for successful operation.

    Key Outcomes

    By implementing these discovery patterns, ServiceNow customers can:

    • Efficiently discover and manage Azure DNS resources within their IT environment.
    • Ensure all relevant data is captured in the CMDB, leading to improved operational insights.
    • Maintain updated and accurate information regarding DNS zones and their record sets.

    Prerequisites

    • Verify Privileges: Ensure a user has the API Management Service Reader role in the Azure Console.
    • Create Azure Service Principal Credentials: Follow guidelines to create necessary credentials.
    • Configure Azure Service Account: Set up a cloud account for Azure.
    • Create Discovery Schedule: Establish a schedule for running discovery based on Azure service accounts.
    • Verify REST API Permissions: Download the necessary patterns spreadsheet to manage user permissions effectively.

    The Discovery and Service Mapping Patterns application uses the Azure - DNS Zones (LP) and Azure - DNS Zone Recordsets (LP) Patterns to discover Azure Domain Name System (DNS) definitions (zones and their respective record sets). Discovering some of these resources requires updating the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Prerequisites

    Verify privileges
    On the Microsoft Azure Console, provide a user with the API Management Service Reader role.
    Create Azure Service Principal credentials
    For more information see: Create Azure cloud credentials.
    Configure Azure service account
    For more information, see Set up a cloud account for Azure.
    Create discovery schedule
    Create a schedule for the relevant Azure service accounts. For more information, see Create a discovery schedule in Cloud Discovery Workspace.

    Verify the REST API Permissions

    Download the Cloud Discovery patterns spreadsheet so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Azure - DNS Zones (LP) and Azure - DNS Zone Recordsets (LP) Patterns.

    Resources discovered by the Azure - DNS Zones (LP) pattern
    Table 1. DNS Zone [cmdb_ci_dns_zone]
    Field Description
    Name [name] The name of the DNS Zone.
    Number Of RecordSets [number_of_recordsets] The number of the recordsets defined within the DNS Zone.
    Operational status [operational_status] The operational status of the DNS Zone.
    State [state] The state of the DNS Zone.
    Install Status [install_status] The install status of the DNS Zone.
    Comments [comments] The field for general comments.
    Resources discovered by the Azure - DNS Zone Recordsets (LP) pattern
    Table 2. DNS Discovery po [cmdb_ci_dns_alias]
    Field Description
    Name [name] The name of the DNS alias record.
    IP Address [ip_address] IP address of the DNS alias record.
    Comments [comments] Unique identifier for an Azure DNS zone combining service account ID, DNS zone name, and a fixed hash suffix.
    Operational status [operational_status] The operational status of the DNS alias record.
    Table 3. DNS Name [cmdb_ci_dns_name]
    Field Description
    Name [name] The name of the DNS Name record.
    Operational status [operational_status] The operational status of the DNS record.
    Comments [comments] Unique identifier for an Azure DNS zone combining service account ID, DNS zone name, and a fixed hash suffix.

    CI relationships

    These relationships are created to support Azure DNS zone discovery.
    CI Relationship CI
    Resource Group [cmdb_ci_resource_group] Contains::Contained by DNS Zone [cmdb_ci_dns_zone]
    These relationships are created to support Azure DNS zone record set discovery.
    CI Relationship CI
    DNS Zone [cmdb_ci_dns_zone] Contains::Contained by DNS Name [cmdb_ci_dns_name]
    DNS Zone [cmdb_ci_dns_zone] Contains::Contained by DNS Alias [cmdb_ci_dns_alias]
    DNS Name [cmdb_ci_dns_name] Used by::Uses DNS Alias [cmdb_ci_dns_alias]
