Azure Web Application Firewall Policy pattern-based discovery
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 - Web Application Firewall Policy - 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.
