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.

Version 7.2 of ILMT was announced on July 28, 2009 via 209-220 with electronic general availability on July 31, 2009 and physical media general availability on August 21, 2009. Existing ILMT V7.1 customers should prompty install the V7.2 release.

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:
- when ILMT does not yet provide support for the Eligible Virtualization Environment
- (In order to be notified when ILMT support for eligible virtualization technologies become available, customers need to subscribe to "My Notifications".
- if your Enterprise has fewer than 1,000 employees and contractors worldwide, you are not a Service Provider, and you have not contracted with a Service Provider to manage your Eligible Virtualization Environment
- if your Enterprise’s total physical capacity of your servers with an Eligible Virtualization Environment, measured on a Full Capacity basis, but licensed using sub-capacity terms is less than 1,000 PVUs.
For the above exceptions, customers must manually manage, track, and prepare a Manual Calculation of Virtual Capacity worksheet for each server or cluster (group of servers). 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.
