1. Scope

OpenLM supports license monitoring of a wide, and ever growing variety of license managers.

This application note elaborates the steps required to configure OpenLM to interface the Licman license manager, to monitor license usage and obtain license statistics.


2. Interfacing the Licman license server

The Licman license server should be queried locally, by the OpenLM Broker. The query response will consequently be propagated to the OpenLM Server, for monitoring and reporting purposes. Hence, the OpenLM settings require installing the OpenLM Broker on the same machine as the Licman license server, and installing the OpenLM Server on any Windows based machine on the network.

It is recommended to consult the OpenLM system requirements page prior to installation.
