    Summary of Azure Application LB pattern-based discovery

    The Azure Application LB pattern-based discovery enables ServiceNow customers to discover Azure application load balancers within their cloud environments using Discovery and Service Mapping Patterns. This capability requires the latest version of the Discovery and Service Mapping Patterns application and adherence to Microsoft Azure discovery prerequisites. It supports discovery for standard Azure environments as well as Azure GovCloud (US) by configuring appropriate datacenter URLs and Azure service accounts.

    Key Features

    • Discovery Coverage: Identifies Azure application load balancers and related components such as load balancer IP addresses, pools, and services.
    • CMDB Population: Automatically populates key configuration item (CI) tables in the CMDB, including:
      • Cloud Load Balancer (cmdbcicloudloadbalancer): Captures attributes like name, object ID, location, IP address, DNS details, and installation status.
      • Cloud LB IPAddress (cmdbcicloudlbipaddress): Stores IP address details, distinguishing between private and public types.
      • Load Balancer Pool (cmdbcilbpool): Contains pool-specific information such as name, object ID, and location.
      • Load Balancer Service (cmdbcilbservice): Records service-level data including port information and location.
    • CI Relationships: Establishes relationships between load balancers, IP addresses, pools, services, Azure datacenters, cloud subnets, and resource groups to provide a complete topology of the load balancer environment.
    • Azure Tag Discovery: Collects Azure tags associated with load balancers and stores them as key-value pairs linked to the corresponding load balancer CI, enhancing resource categorization and management.

    Practical Benefits for ServiceNow Customers

    • Enables comprehensive visibility into Azure application load balancers and their components within the CMDB, supporting better cloud infrastructure management.
    • Facilitates automated and accurate discovery processes that reduce manual configuration and errors.
    • Supports compliance and governance by mapping load balancers to resource groups and subnets, and by enabling GovCloud discovery.
    • Enhances operational efficiency by providing detailed relationships and tag information useful for reporting, impact analysis, and service mapping.

    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 components 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.

    Table 5. CI relationships
    CI Relationship CI
    Cloud Load Balancer [cmdb_ci_cloud_load_balancer] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]
