The IBM License Metric Tool [ILMT] helps you maintain an inventory of the PVU based software deployed for your Full Capacity or Virtualization (Sub-) Capacity environment, and measures the PVU licenses required by software Product. It is intended to help you manage your IBM software licensing requirements, and help you maintain an audit ready posture. Customers are responsible for supplying hardware and installation services required for installing the tool.

ILMT version 9.2 was announced on March 17, 2015 via Software Announcement 215-076. Customers have 90 days from first eligible Virtualization (Sub)-capacity product deployment to install and begin using ILMT for supported virtualization technologies. Customers with earlier versions should promptly install the latest V9.2 release.

On June 30th, 2019 HCL acquired from IBM select IBM collaboration, commerce, digital experience, AppScan & BigFix solutions.

ILMT uses BigFix platform. Please refer to the ILMT and HCL BigFix FAQ for additional information on the ILMT and HCL relationship.

Use of IBM License Metric Tool

The use of IBM License Metric Tool is recommended for Full Capacity PVU environments, and is mandatory for use with PVU sub-capacity licensing.

Exceptions to this requirement are:

1. when ILMT does not yet provide support for the Eligible Virtualization Environment

2. if your Enterprise has fewer than 1,000 employees and contractors, you are not a Service Provider (an entity that provides information technology services for end user customers, either directly or through a reseller), and you have not contracted with a Service Provider to manage your environment, and the total physical capacity of your Enterprise servers measured on a full capacity basis, but licensed under Sub-Capacity Licensing terms, is less than 1,000 PVUs.

3. if your servers are licensed to full capacity.

For the above exceptions, customers must manually manage, track, and prepare a Manual Calculation of Virtual Capacity worksheet for each server. For more details about the requirements for this worksheet, you can go to Virtualization Capacity License Counting Rules or use the Manual Calculation of Virtual Capacity worksheet available from the right hand nav bar.

Customers must maintain documentation for at least two years to demonstrate ongoing compliance with these Sub-Capacity Licensing terms.

For details of Sub-capacity licensing requirements, including requirements for maintaining documentation, see the Passport Advantage Virtualization Capacity (Sub-capacity) Licensing and the Virtualization Capacity License Counting Rules.
