    Key Features

    • Data Collection: Discovery captures relevant data about Azure Classic Load Balancers, populating the Configuration Management Database (CMDB) with details such as Object ID, Name, State, and Install Status.
    • Field Descriptions: Each discovered resource includes specific fields:
      • Cloud Load Balancer: Includes Object ID, Name, State, and Install Status.
      • Cloud LB IP Address: Captures Object ID, Name, IP Address, IP Address Type, FQDN, and Install Status.
      • Load Balancer Service: Identifies Object ID, Name, Port, and Install Status.
      • Load Balancer Pool: Contains Object ID, Name, and Install Status.
    • CI Relationships: The Azure - Classic LB (LP) pattern establishes relationships between various configuration items (CIs) to facilitate effective resource management and tracking.

    Key Outcomes

    By utilizing the Azure Classic Load Balancer pattern-based discovery, ServiceNow customers can efficiently manage their Azure resources, maintain accurate configuration data, and enhance their visibility into cloud infrastructure. This capability supports better decision-making and operational efficiency within cloud environments.

    Discovery and Service Mapping Patterns finds Azure Classic 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.

    Data collected by Discovery during horizontal discovery

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

    Table 1. Cloud Load Balancer [cmdb_ci_cloud_load_balancer]
    Field Description
    Object ID [object_id] A unique identifier, allocated by Azure for this resource.
    Name [name] The name of the load balancer.
    State [state] The current state of the load balancer.
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Table 2. Cloud LB IP Address [cmdb_ci_cloud_lb_ipaddress]
    Field Description
    Object ID [object_id] A unique identifier, allocated by Azure for this resource.
    Name [name] IP address of the load balancer.
    IP Address [ip_address] IP address of the load balancer.
    IPAddress Type [ipaddress_type] The type of the IP address, which can be private or public.
    Fully qualified domain name [fqdn] The fully qualified domain name (FQDN) of the load balancer.
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Table 3. Load Balancer Service [cmdb_ci_lb_service]
    Field Description
    Object ID [object_id] A unique identifier, allocated by Azure for this resource.
    Name [name] The name of the load balancing rule or inbound NAT rule.
    Port [port] The TCP port that the load balancer service listens to.
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Table 4. Load Balancer Pool [cmdb_ci_lb_pool]
    Field Description
    Object ID [object_id] A unique identifier, allocated by Azure for this resource.
    Name [name] The name of the backend address pool.
    Install Status [install_status] Install status of the resource. Default value is Installed.

    CI relationships

    The Azure - Classic LB (LP) pattern creates these relationships to support Azure Classic Load Balancer discovery.

    CI Relationship CI
    Cloud Load Balancer [cmdb_ci_cloud_load_balancer] Owns::Owned by Cloud LB IP Address [cmdb_ci_cloud_lb_ipaddress]
    Cloud Load Balancer [cmdb_ci_cloud_load_balancer] Hosted on::Hosts Azure Datacenter [cmdb_ci_azure_datacenter]

    Connections discovered by Service Mapping during top-down discovery

    The Azure LoadBalancer TD pattern performs top-down discovery of Azure Classic Load Balancers. Service Mapping discovers cluster connections from the load balancer service to backend pool member IP addresses using either load balancing rules or inbound NAT rules.
