Monitoring the Green Hills license manager with OpenLM – KB4001v


OpenLM incorporates the capability to monitor the usage of Green Hills licenses. There are two options to query this type of License Server:

  1. The quick method:
    Remotely query the license server from the OpenLM Server. This method only provides license usage information.
  2. The robust method:

Query the license server locally by the OpenLM Broker and propagate the information back to the OpenLM Server. This option provides additional benefits, such as enhanced robustness to communication failure and bypassing of Networking and Security limitations. This method may provide additional benefits in the future, such as reading and parsing the Green Hills log files.

This text is a query of the License server. It indicates whether a connection to that server is established, and the License server is active.

Configuring the OpenLM Server is usually enough for monitoring licensed applications. The OpenLM Broker is an optional component, which provides many benefits for monitoring different types of license managers.

In the case of the Green Hills license manager, the benefits of installing the OpenLM Broker have enhanced robustness to communication failure, through message buffering and bypassing of Networking and Security limitations.
