What is Greenhills LM?

The Greenhills License Manager (or GHS LM) is a license manager that is mandatory for all GHS software running on a host machine (as opposed to their embedded products for IoT and other devices). There are 4 available license models:-

  • Floating License. The license keys are installed on a network license server
  • Named-user. The license keys are installed on the network license server, but only the named user or the administrator can access the license.
  • Computer-locked. The license key is installed on a specific machine
  • Dongle-locked. The rights to using the license are stored in a device, such as a dongle. Machines which are cleared to use the software must also have a license key installed.

There is also a “Legacy” license available for very old software versions.

OpenLM provides the following functionality for monitoring LM-X Licenses:-

  • Denials Reporting No
  • Report resolution By Minute
  • Borrowed License reporting No
  • Expiration Date reporting Yes
  • Multiple Server Redundancy Support No
  • Token License Support No

Greenhills GHS is only one of over 25 license managers that OpenLM can manage. Check the list.
