Azure DNS zones and record sets discovery using Patterns

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 may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Request apps on the Store

Visit the ServiceNow Store to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

To learn about Azure DNS zones and record sets and their version that you can discovery, refer to Detailed information on products discovered by ITOM Visibility.

For more information on Azure cloud discovery, see Discovery for Microsoft Azure.

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.

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.
