    Summary of Azure Application LB pattern-based discovery

    The Azure Application LB pattern-based discovery enables ServiceNow customers to identify and map Azure application load balancers within their cloud environments. This pattern uses Discovery and Service Mapping Patterns to populate detailed load balancer configuration items (CIs) in the Configuration Management Database (CMDB), supporting accurate asset and service visibility for Azure cloud resources.

    To leverage this pattern effectively, customers must ensure they meet Microsoft Azure discovery prerequisites and configure discovery schedules appropriately, especially to support Azure GovCloud (US) accounts by using the correct datacenter URL during Azure service account setup.

    Some Azure load balancer resources may require updating to the latest Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Key Features

    • Discovery of Azure Load Balancers: The pattern identifies Azure cloud load balancers and gathers essential attributes such as name, object ID, location, state, IP address, DNS details, and install status.
    • Detailed CI Classes: Includes discovery and population of multiple related CMDB tables:
      • Cloud Load Balancer [cmdbcicloudloadbalancer]: Core load balancer CIs with identifying and status fields.
      • Cloud LB IPAddress [cmdbcicloudlbipaddress]: IP addresses associated with load balancers, specifying public or private types.
      • Load Balancer Pool [cmdbcilbpool]: Pools belonging to load balancers with location and identification data.
      • Load Balancer Service [cmdbcilbservice]: Services defined on load balancers, including listening TCP ports.
    • CI Relationships: The pattern establishes relationships to reflect the infrastructure hierarchy and ownership, such as:
      • Load balancers hosted on Azure datacenters.
      • Ownership of IP addresses by load balancers.
      • Load balancer pools and services hosted on load balancers.
      • Load balancers containing cloud subnets and resource groups.
    • Tag Discovery: Azure tags are collected and stored as key-value pairs in the CMDB Key Value [cmdbkeyvalue] table, linked to the corresponding load balancer CI, supporting enhanced categorization and filtering capabilities.

    Practical Benefits for ServiceNow Customers

    • Provides comprehensive, structured data on Azure load balancers to maintain accurate CMDB entries.
    • Enables improved visibility into Azure cloud infrastructure components and their relationships.
    • Supports compliance and operational workflows by reflecting the current state and configuration of load balancers.
    • Facilitates management of IP addressing and networking through detailed IP and service mapping.
    • Helps organize cloud resources using Azure tags, aiding in governance and reporting.

    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.
