    Summary of Integrating with the IBM License Metric Tool (ILMT) or BigFix Inventory using v2 APIs

    The integration of IBM License Metric Tool (ILMT) and BigFix Inventory with ServiceNow via version 2 APIs allows customers to import usage data from IBM servers. This facilitates tracking and optimizing licensing for Processor Value Units (PVU), Resource Value Units (RVU), and Virtual Processor Core (VPC) for IBM software products.

    Key Features

    • Establishes connections between IBM servers and the ServiceNow AI Platform using HTTP/HTTPS.
    • Retrieves peak usage data during specified periods from ILMT or BigFix Inventory.
    • Utilizes a default transform map to process imported data into ServiceNow tables.
    • Enables viewing of peak usage metrics for IBM software products, both overall and by device.

    Prerequisites

    To successfully implement this integration, customers must:

    • Install and configure ILMT or BigFix Inventory on a physical host or virtual machine.
    • Ensure proper configuration of all required CI data to enable accurate CI record creation in the CMDB.
    • Install ILMT version 9.2.24 or later, as earlier versions restrict data import capabilities.
    • Configure agents to comply with IBM usage measurement guidelines.
    • Request and install the IBM License Compliance for Software Asset Management application from the ServiceNow Store.
    • Set the Software Asset Management property for ILMT API version to v2.

    Key Outcomes

    By integrating with ILMT or BigFix Inventory, ServiceNow customers can:

    • Track and manage IBM licenses effectively.
    • Access detailed usage metrics over an aggregated period of up to 90 days.
    • Identify devices running IBM software, enhancing resource management and compliance efforts.

    You can use version 2 of the IBM License Metric Tool (ILMT) and BigFix Inventory integration APIs to create a connection between your IBM servers and the ServiceNow AI Platform.

    This connection enables you to import usage data into your ServiceNow instance so that you can track and optimize full capacity and sub-capacity processor value unit (PVU) and resource value unit (RVU) licensing as well as sub-capacity virtual processor core (VPC) licensing for your IBM software products.

    See REST API resources and HTTP methods for more information on the ILMT and BigFix Inventory integration APIs.

    Integration between ILMT and ServiceNow.

    The ILMT and BigFix Inventory integration enables you to create connections between one or more IBM servers and the ServiceNow AI Platform using HTTP or HTTPS. When you initiate the integration, you receive an IBM Server connection alias that you can use to set up your IBM server connections. If a connection is successful, the Software Asset Management application retrieves peak usage data within the aggregated period that you defined in ILMT or BigFix Inventory.

    Prerequisites

    To track your IBM full capacity and sub-capacity PVU, RVU, and VPC licenses using this integration, you must complete the following prerequisites:
    • Install, set up, and run ILMT or BigFix Inventory on a physical host or virtual machine (VM).
      Important:
      When you are setting up ILMT, ensure that all required configuration item (CI) data, including serial numbers, names, and IP addresses, is configured correctly so that your ServiceNow instance can accurately create corresponding CI records in the Configuration Management Database (CMDB). Refer to KB0691430 for more details.
    • Install ILMT version 9.2.24 or later.
      Note:
      If you are using ILMT version 9.2.23 or earlier, you can import usage data only against your discovered IBM software products and not against the hosts that are running those products.
    • Configure your IBM ILMT agents to scan your physical hosts or VMs in compliance with IBM usage measurement guidelines.
      Note:
      Refer to Measuring License Use for more information on IBM usage measurement guidelines.
    • Enable ILMT or BigFix Inventory to discover the configurations of both physical hosts and VMs as well as the relationships between them.
    • Classify and bundle IBM components into IBM products through ILMT or BigFix Inventory.
    • Request and install the IBM License Compliance for Software Asset Management application from the ServiceNow® Store. See Request the IBM License Compliance for Software Asset Management application for IBM License Metric Tool (ILMT) and BigFix Inventory integrations for detailed instructions.
    • Set the Connect to ILMT using (sn_samp_ibm_lic.ilmt_api_version) Software Asset Management property to v2 API's. For more details on this property, see Software Asset Management properties.
