Monitor Network License Manager
This topic describes several utilities that you can use to manage the network license
manager. For detailed information about these utilities, see the License
Administration Guide, included in PDF format in your MATLAB® installation
LMTOOLS is available for Windows® computers only. All operating systems can use the command line utilities.
Using LMTOOLS (Windows Only)
On Windows computers, FlexNet® Publisher licensing includes a tool, called LMTOOLS. Using LMTOOLS, you can perform many license management tasks, such as:
Get the status of the network license manager.
Start and stop the network license manager.
Configure the network license manager as a service.
To illustrate, the following example shows how to use LMTOOLS to see the current status of the network license manager:
Start LMTOOLS by double-clicking the
lmtools.exefile in the
matlabrootis your MATLAB installation folder and
is a platform-specific subfolder, such as
Select the Server Status tab.
Click the Perform Status Enquiry button. LMTOOLS displays the same information as if you had entered the command
lmutil lmstat -a.
Using Command-Line Utilities
FlexNet licensing includes a set of license management utilities that you can use to start, stop, and monitor the network license manager.
On Windows computers, FlexNet packages all the utilities in a single, command-line executable called
lmutil.exe. This program is available in the
matlabroot is your MATLAB installation folder and
$ARCH is a
platform-specific subfolder, such as
win64. For example, to run a
status check of the network license manager, open a DOS command window and run
lmstat as an
lmutil lmstat -a -c "C:\Program Files\MATLAB\R2022b\etc\license.dat"
-a option requests a verbose listing. You must also include
-c option to specify the license file to use. You must use
this option with every
lmutil option. If your installation path
contains spaces, enclose the path in quotes. The following listing is a portion of
