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

    ServiceNow customers can leverage version 2 of the IBM License Metric Tool (ILMT) and BigFix Inventory integration APIs to connect IBM servers with the ServiceNow AI Platform. This integration facilitates the import of usage data into ServiceNow, enabling effective tracking and optimization of IBM software licensing, including full capacity and sub-capacity Processor Value Unit (PVU), Resource Value Unit (RVU), and Virtual Processor Core (VPC) licenses.

    Key Features

    • Supports connection to one or more IBM servers via HTTP or HTTPS.
    • Generates an IBM Server connection alias to configure server connections in ServiceNow.
    • Imports peak usage data within aggregated periods defined in ILMT or BigFix Inventory, up to 90 days.
    • Uses default transform maps to process imported data into ServiceNow tables for seamless data integration.
    • Provides visibility into peak license usage by IBM software products and by physical hosts or virtual machines (VMs).
    • Enables viewing of all devices running IBM software products to support license compliance and management.

    Prerequisites

    • Install and configure ILMT (version 9.2.24 or later) or BigFix Inventory on physical hosts or VMs.
    • Ensure all required configuration item (CI) data such as serial numbers, names, and IP addresses are accurately configured to enable correct CMDB record creation.
    • Configure ILMT agents to scan hosts and VMs following IBM usage measurement guidelines.
    • Enable ILMT or BigFix Inventory to discover host and VM configurations and their relationships.
    • Classify and bundle IBM components into products within ILMT or BigFix Inventory.
    • Request and install the IBM License Compliance for Software Asset Management application from the ServiceNow Store.
    • Set the Software Asset Management property to use the v2 APIs for ILMT integration.

    Practical Benefits

    By integrating ILMT or BigFix Inventory with ServiceNow using the v2 APIs, customers can achieve accurate and comprehensive tracking of IBM license usage. This supports optimized license management, cost control, and compliance assurance by providing detailed insights into license consumption at both aggregate and device-specific levels.

    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.
