Summary

The GibbsCAM Network License (NLO) Server uses Reprise License Manager (RLM) to provide real-time visibility into license usage. Administrators can track which users are consuming licenses, which features are in use, and how many licenses are currently available.

This article explains how to monitor license usage using the RLM Web Administration interface and related tools.

TABLE OF CONTENTS

Overview

RLM provides a built-in web-based administration interface that allows license administrators to monitor real-time usage of GibbsCAM licenses.

From this interface, administrators can view:

  • Active license users

  • License checkout duration

  • Hostnames of connected machines

  • Feature usage (e.g., Mill, Lathe, 5-Axis)

  • Available vs. used licenses

Accessing the RLM Web Interface

  1. Open a web browser on the license server or a workstation with network access.

  2. Navigate to the RLM administration page:

http://localhost:5054


If accessing remotely, replace localhost with the server hostname or IP address.

Viewing Active License Usage

Once logged into the RLM Web Interface:

  1. Click the Status button on the left menu.

  2. Under Server status click the Gibbsnet button.

  3. Locate the License Pool Status chart.
    This chart will display:

  • Name of the licensed option

  • Count of how many total seats of each option

  • How many seats are currently In Use

  1. Clicking on the Usage button to the right will display:

  • Username

  • Hostname

  • Checkout time

  • License expiration (if roaming or timed policies apply)

Note: The Remove button will remove the license from the user and kick them out of GIbbsCAM, and potentially lose any unsaved work.

Understanding License Usage Data

The usage table provides the following key information:

Field

Description

User

The logged-in Windows username or RLM-reported user

Host

The workstation name requesting the license

Feature

The GibbsCAM module or license feature in use

Start Time

When the license was checked out

Duration

How long the license has been in use

Monitoring License Availability

On the same interface, administrators can also view:

  • Total number of licenses

  • Number currently in use

  • Number available

This helps identify:

  • Peak usage periods

  • License shortages

  • Unused or idle licenses

Checking License Logs

RLM also provides log output that can be used for historical analysis.

To review logs:

  1. Open the RLM Web Interface

  2. Click the Status button on the left menu.

  3. The two log files are located by:
    Click the SHOW rlm Debug Log

and
Under Dbug Log click the Gibbsnet button.

These files are also located on the server in:
C:\Program Files\GibbsCAM\GibbsCAM NLO Server 2024
gibbsnet.dlog

RLMLog.log

  1. Review events such as:

    • License checkout

    • License return

    • Denied license requests

    • Server startup/shutdown events

Optional: Command Line Monitoring

Advanced administrators may also use network monitoring tools or RLM command-line utilities (if installed) to query license usage.

However, the RLM Web Interface is the recommended method for most environments.

Tracking Roaming Licenses

Roaming licenses will also appear in the usage list.

They are typically marked as:

  • Checked out user

  • Roaming status (if displayed by version)

  • Expiration date or duration remaining

Roaming licenses remain unavailable until:

  • They are manually returned, or

  • The roaming period expires

Troubleshooting

Problem: No Users Show in License Usage

Possible Causes

  • No active users currently checked out licenses

  • ISV server is not running

  • Web interface is not connected to the correct server instance

Resolution

Verify the GibbsRLMServer service is running and that users are actively launching GibbsCAM.


Problem: User Appears Stuck Using a License

Possible Causes

  • Workstation disconnected unexpectedly

  • Network interruption during session

Resolution

Wait for RLM timeout policies or restart the license server if appropriate. Contact the user to close GibbsCAM properly.


Problem: License Count Does Not Match Expected Usage

Possible Causes

  • Reserved licenses configured in options file

  • Roaming licenses in use

  • Multiple ISV features consuming different license types

Resolution

Check the RLM status page and review options file configuration.

Best Practices

  • Regularly review license usage during peak hours

  • Identify heavy users for capacity planning

  • Monitor for idle or orphaned sessions

  • Use groups and reservations to control allocation

  • Review logs weekly for denied license requests

Expected Result

Administrators can clearly see real-time GibbsCAM license usage, helping ensure efficient allocation of network licenses and proactive capacity planning.
