Monitor Network License Manager- MATLAB & Simulink (2024)

Monitor Network License Manager

This topic describes several utilities that you can use to manage the network licensemanager. For detailed information about these utilities, see the LicenseAdministration Guide, included in PDF format in your MATLAB^® installation(matlabroot\etc\LicenseAdministration.pdf).

LMTOOLS is available for Windows^® computers only. All operating systems can use the command lineutilities.

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 currentstatus of the network license manager:

Start LMTOOLS by double-clicking thelmtools.exe file in thematlabroot\etc\$ARCHfolder, where matlabroot is your MATLAB installation folder and$ARCH is aplatform-specific subfolder, such as win64.
Select the Server Statustab.
Click the Perform Status Enquirybutton. LMTOOLS displays the same information as if you had entered thecommand lmutil lmstat -a.

Using Command-Line Utilities

FlexNet licensing includes a set of license management utilities that you canuse to start, stop, and monitor the network license manager.

On Windows computers, FlexNet packages all the utilities in a single, command-line executable calledlmutil.exe. This program is available in thematlabroot\etc\$ARCH folder,where matlabroot is your MATLAB installation folder and $ARCH is aplatform-specific subfolder, such as win64. For example, to run astatus check of the network license manager, open a DOS command window and runlmutil specifying lmstat as anargument:

lmutil lmstat -a -c "C:\Program Files\MATLAB\R2024a\etc\license.dat"

The -a option requests a verbose listing. You must also includethe-c option to specify the license file to use. You must usethis option with every lmutil option. If your installation pathcontains spaces, enclose the path in quotes. The following listing is a portion ofthe information returned.

To view a list of all the utilities in the lmutil package,type:

lmutil -h

To get help for a particular utility, type the name of the utility with the-h option, as in the following example:

lmutil lmstat -h

On Linux and macOS computers, these license management utilities are individualexecutables, available in thematlabroot/etc folder. Forexample, to view the status of the network license manager, use thelmstat utility, as follows:

lmstat -h

The following table lists the names of the most useful license management toolsincluded.

Utility	Description
`lmdiag`	Diagnose license checkout problems.
`lmdown`	Shut down all license daemons (both`lmgrd` and all vendor daemons) on thelicense server node.
`lmhostid`	Report the host ID of a system.
`lmreread`	Make the network license manager reread the licensefile and start any new vendor daemons. Note When you use `lmreread` to reprocessa license file for a user-based license, changes to`INCLUDE` statements in theassociated network license manager options file takeeffect after a 15-minute delay.
`lmstat`	Display the status of all network licensingactivities.
`lmswitchr`	Switch to another report log file.
`lmver`	Determine the version of a library or binaryfile.
