OpenLM Platform monitors licenses for software from GNS (Gesellschaft für numerische Simulation) through OpenLM Broker. Broker reads the product names from your GNS license file, then runs the GNS `licstat.exe` utility for each product to read its license total, usage, and expiration date. This page lists the prerequisites. To get the configuration steps, contact OpenLM Support.

## Before you begin

Confirm these prerequisites:

- OpenLM Platform.
- [OpenLM Broker](https://www.openlm.com/documentation/cloud/data-collection/openlm-broker/) v25.11.4.1221 or higher, approved in [Broker Hub](https://www.openlm.com/documentation/cloud/data-collection/broker-hub/).
- OpenLM Broker installed on a machine that can run `licstat.exe` against the GNS license server.
- A copy of your GNS license file on the Broker machine. Broker queries only the products that the license file lists.
