Installing IBM License Metric Tool (ILMT) for Linux & Windows – Step-by-Step


What is IBM License Metric Tool (ILMT)?

The IBM License Metric Tool (ILMT) is a software asset management tool designed to help users manage their IBM environments and maintain an audit-ready posture. ILMT is provided by IBM for free, however, customers are responsible for supplying the necessary hardware and installing it themselves (or with assistance from a third party).

We have compiled step-by-step instructions on how to install ILMT for both Linux and Windows, with all the resources necessary for a successful installation. Even still, ensuring that ILMT is set up correctly and in a way that will best serve your organization can be an extremely daunting task. Here at Anglepoint, we have a dedicated team of ILMT experts who have helped many clients successfully install and optimize ILMT.

IBM License Metric Tool (ILMT) Frequently Asked Questions (FAQs)

What is the ILMT Agent?

The ILMT Agent is one of three ILMT components (the other two being the BigFix Platform and relevant ILMT application). The Agent identifies IBM software deployed and assigned to each virtualization and device through regular scans. If the ILMT Agent is not deployed, then the license fee will be calculated for full capacity.

How is IBM PVU Calculated?

The formula for calculating IBM PVUs is:

Full Capacity = PVU-per-core * the number of sockets on the physical host * the number of cores-per-socket on the physical host
Sub-Capacity = PVU-per-core * the number of cores assigned to the virtual machine (VM)

What is IBM sub-capacity licensing?

Sub-capacity licensing allows organizations to license eligible software products for less than the full capacity of the server or group of servers. To qualify for sub-capacity licensing, customers must install ILMT within 90 days of the first use of an eligible sub-capacity product and produce and retain quarterly reports for at least two years and make them available at IBM’s request.
