Detailed License Utilization Analysis

Perhaps you are curious about your organization's utilization of your FlexSim licenses. Maybe you have anecdotal accounts where your modelers can't get a license, and you want to quantify how often all licenses are in use. Perhaps you want to justify purchasing extra FlexSim seats, or wonder if you can get away with decreasing your seat count. Maybe you are just curious how much of your engineers' time is spent in simulation and you want to graph FlexSim utilization trends.

When you host your own license server, FlexSim (the company), does not receive your usage logs. We have no way of knowing your utilization. That information resides inside, and is owned by, your organization.

Whatever the reason, if you want a detailed analysis of your license utilization, you have 3 options:


The fastest and least expensive way to get info is just to eyeball the vendor daemon log. If you don't have too many seats or users, you may just be able to scroll through the raw logs and figure out what is going on.

See the additional answers below for descriptions of the various entries you'll find in your log file:


Some organizations have created their own scripts to parse through the data in their log file and calculate exactly what they're looking for. Usually there is a specific need, and so these scripts are quick, dirty, and single purpose, probably not worth sharing. However, if you have created a script for parsing log files, and you don't mind sharing, feel free to post it to a comment below.

Log Entries

Here are explanations of some of the common log entries you'll find as you view the body of your vendor daemon log file



example line:

21:39:34 (flexsim) OUT: "consolescript" CompyUser@AWESOMECOMPY

That means that the "consolescript" feature was checked out to a PC named AWESOMECOMPY at time 21:39:34. User CompyUser was logged into Windows at the time. An OUT log entry is added to the log when FlexSim starts. It checks out features from your license server.



example line:

 1:29:37 (flexsim) IN: "dragdropconnect" CompyUser@AWESOMECOMPY

IN means that the feature was checked back in. This happens when either:

  • FlexSim is closed by the user
  • The server has been unable to contact the client PC for the timeout period (typically 15 minutes if you've used the Options file shipped with our FlexSim License Server files). The FlexSim instance will have lost its license earlier than that if it can't contact the license server. I don't remember the exact heartbeat period, but it is 1-5 minutes. If the client PC can't contact the license server within a heartbeat, it will warn the user to save now, then it will close or revert to unlicensed Express version.



example line:

21:36:45 (flexsim) TIMESTAMP 2/22/2017

Each individual line of the log file only includes the time of day (see IN and OUT examples above), so you will need to find the closest TIMESTAMP line above the IN/OUT/etc. log entry you are looking at in order to infer the date for the other log entries.



example line:

6:22:50 (flexsim) DENIED: "commercialuse" CompyUser@AWESOMECOMPY  (License server system does not support this version of this feature. (-25,334))

For the example line above, on a client PC (AWESOMECOMPY) the user (CompyUser) opened FlexSim version 17.1 (for example), which then requests 17.1 features from the license server. The server responds saying DENIED because "License server system does not support this version of this feature", if your license server is hosting an older version of the license, like 17.0 or 16.2.

You should also get a DENIED log entry if all seats are currently in use, but the info message would be "Licensed number of users already reached."

Log Information

The vendor daemon log can help you diagnose issues as you configure your license server.

You will know that you have successfully configured and started your license server when you see FlexSim's features listed, as in this example text found near the top of your vendor daemon log:

8:00:03 (flexsim) ALL FEATURES: INACTIVITY TIMEOUT set to 900 seconds
8:00:03 (lmgrd) flexsim using TCP-port 56914

The above chunk of log file shows the lmgrd port to connect to when configuring FlexSim (26914, as shown in this example, is our default port) and the vendor daemon's port (56914, make sure this port is available through the firewall, in addition to the lmgrd port). It also shows that the server is successfully hosting FlexSim's features such as serverfeature, commercialuse, compile, xmlsaveload, etc. Lastly, you see that it is using the Options file flexsim.opt, where INACTIVITY TIMEOUT is set to 900 seconds (which is the minimum allowed by the system, and is the setting in our default options file).

So if you see all that in your log file, you know your license server is correctly hosting your licenses. If you still have trouble with your client PCs getting licensed, then it is some other issue, like connectivity (firewalls, network settings, etc). See the troubleshooting section at the end of our License Server Installation Instructions for more info.

These screenshots are more illustrative of the view of the log file through lmtools:


  1. lmgrd.exe is listening on port 26914. This is the port the licensing service will use when listening for client PC communication.
  2. The bootstrap license file flexsim.lic was found and loaded. (This is not a license file specific to you and does not contain your license info. FlexSim licenses use Trusted Storage and licenses are activated to your license server using flexsimserveractutil.exe).1673709041097.png
  3. The flexsim.opt Options file was found and loaded.
  4. A list of product features activated in your server's Trusted Storage. Your feature set may differ somewhat from this example, depending on your license and product, but you should see several of the features above.
  5. 900 seconds is the minimum timeout allowed by FlexNet, and we configure our installation to use this minimum value using the options file.
  6. The flexsim.exe vendor daemon is using port 56914.
