    Summary of Azure Application LB pattern-based discovery

    The Azure Application LB pattern-based discovery enables ServiceNow customers to discover and map Azure application load balancers within their cloud environment using Discovery and Service Mapping Patterns. This process updates the Configuration Management Database (CMDB) with detailed data about Azure load balancer resources, supporting accurate service mapping and cloud infrastructure visibility.

    Key Features

    • Pattern-based discovery: Uses the Azure - Application LB (LP) pattern to identify and collect information on Azure load balancers and related components.
    • Prerequisites: Requires meeting Microsoft Azure discovery prerequisites and configuring Discovery schedules appropriately, including specific setup for Azure GovCloud accounts using datacenter URLs.
    • Comprehensive data collection: Discovers key load balancer details such as Name, Object ID, Location, State, IP Address, DNS, and install status, populating corresponding CMDB tables.
    • Relationship mapping: Automatically creates CI relationships linking load balancers to Azure Datacenters, IP addresses, load balancer pools and services, cloud subnets, and resource groups to maintain accurate infrastructure context.
    • Tag discovery: Captures Azure tags and stores them in the Key Value table, associating tags with the Cloud Load Balancer CIs for enhanced filtering and reporting.

    What Customers Can Expect

    By implementing this discovery pattern, ServiceNow customers can expect an automated, accurate population of Azure Application Load Balancer data into their CMDB, improving cloud asset visibility and operational management. The pattern supports governance scenarios by ensuring GovCloud environments are discoverable with correct service account configurations. The established relationships between CIs provide a clear infrastructure topology, aiding troubleshooting, impact analysis, and service mapping. Additionally, tag data integration allows for better categorization and management of Azure load balancer resources.

    Discovery and Service Mapping Patterns finds Azure application load balancers 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.
    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.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Azure - Application LB (LP) pattern.

    CI relationships

    The Azure - Application LB (LP) pattern creates the following relationships and references to support Azure Application LB discovery. References link to records in other tables and don't appear in the CI Relationship [cmdb_rel_ci] table.
