    Summary of Azure Classic Load Balancer Pattern-Based Discovery

    The Azure Classic Load Balancer pattern-based discovery feature in ServiceNow enables the identification and mapping of Azure Classic Load Balancers within your cloud environment. It allows for effective management of these resources by ensuring that data is accurately populated in the Configuration Management Database (CMDB).

    Key Features

    • Pattern-Based Discovery: Utilizes specific patterns to find and document Azure Classic Load Balancers.
    • Data Collection: Essential data regarding load balancers, including unique identifiers, names, states, and install statuses, are collected during the discovery process.
    • CI Relationships: Establishes relationships between various components such as Cloud Load Balancer, Cloud LB IP Address, Load Balancer Service, and Load Balancer Pool to support comprehensive mapping.
    • Service Mapping: Facilitates top-down discovery to identify connections from load balancer services to backend pool member IP addresses.

    Key Outcomes

    By utilizing the Azure Classic Load Balancer discovery feature, ServiceNow customers can expect:

    • Accurate tracking and management of Azure Classic Load Balancers and their associated resources.
    • Improved visibility into the operational state and relationships of cloud components.
    • The ability to maintain up-to-date information within the CMDB, enhancing overall cloud resource management.

    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]
    Load Balancer Service [cmdb_ci_lb_service] Hosted on::Hosts Cloud Load Balancer [cmdb_ci_cloud_load_balancer]
    Load Balancer Pool [cmdb_ci_lb_pool] Hosted on::Hosts Cloud Load Balancer [cmdb_ci_cloud_load_balancer]
    Load Balancer Pool [cmdb_ci_lb_pool] Hosted on::Hosts Load Balancer Service [cmdb_ci_lb_service]
    Resource Group [cmdb_ci_resource_group] Contains::Contained by Cloud Load Balancer [cmdb_ci_cloud_load_balancer]

    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.
