What is FlexLM / FlexNet, and how does OBSERVER make it truly useful?

FlexLM (now known as FlexNet Publisher) is one of the most widely used license managers in the world, employed to manage floating licenses in a wide range of CAD, CAE, EDA, and scientific applications. However, using FlexLM alone is not enough to ensure complete control over licenses: this is where Observer comes in—ABC Interactive’s solution designed to truly optimize the management of floating licenses, turning them into a strategic asset for companies.

What is FlexLM/FlexNet?

FlexLM (Flex License Manager), now distributed by Revenera under the name FlexNet Publisher, is a license management system that enables the shared use of software licenses over a local network. The licenses are “floating,” meaning they can be used by a variable number of users up to the maximum number available, which is managed by a central server.

This architecture is widely used in the engineering and industrial sectors, but it has limitations in terms of:

• Real-time visibility into actual license usage
• Historical Usage Analysis
• Anomaly Detection
• Strategic Planning for Software Investments

Where OBSERVER Comes In

Observer is designed to enhance and extend the capabilities of FlexLM/FlexNet, offering a comprehensive ecosystem for monitoring, analyzing, alerting, and optimizing software licenses.

1. Real-Time Monitoring

Observer’s RealTime module constantly queries the FlexLM servers and provides a view that is updated every minute:

• Who is using what, where, and when
• Available, active, granted, and denied licenses
• Saturated or At-Risk Features
• Critical situations (e.g., expired licenses, servers offline)

2. Advanced Analysis and Reporting

Thanks to interactive charts and customizable reports, ICT managers can:

• Analyze average usage, peaks, and periods of inactivity
• Evaluate usage efficiency by user, department, location, or software
• Identify underutilized or redundant licenses
• Prepare budgets and renewal forecasts

3. Integration with Active Directory

Observer connects to Active Directory to track in detail who is using each license and to generate customized reports for cost centers and business units, facilitating the internal reallocation of IT costs.

4. Alert and Notification System

Licenses about to expire? Server unreachable? Feature at capacity? Observer automatically sends alerts via email or the dashboard, preventing downtime and ensuring business continuity.

5. Easy to install, ready to use

Observer is available as a ready-to-use Linux virtual appliance. Simply install it on an ESX server or a dedicated workstation to start collecting data from your FlexLM servers right away.
