How to Check Wind River Licenses

Wind River is a leading developer of embedded software solutions, best known for its VxWorks real-time operating system, which is used in mission-critical sectors such as aerospace, automotive, industrial, and defense. Its products are often used in enterprise environments where centralized license management is handled by FlexLM.

How can you manage Wind River floating licenses?

Wind River uses the FlexLM license manager to manage its floating licenses. The only way to analyze software usage is through remote commands, from Linux or Windows.

First, you need to download the lmutil application from the Flexera website. It is essential that the version be equal to or higher than the one currently in use on the license server; otherwise, you risk errors or no output.

Second, you need to know the connection port and the server name listed in the license file. The server name must be entered without any DNS suffixes. If necessary, configure the file hosts or resolv.conf.

How do I check the available Wind River licenses?

To view a list of active licenses and their expiration dates, use the following command:

lmutil.exe lmstat -a -c porta@nomeserver

For configurations with a server triad:

lmutil.exe lmstat -a -c porta@server1;porta@server2;porta@server3

For Linux:

lmutil lmstat -a -c porta@server1,porta@server2,porta@server3

Sample output:

Feature       Version    #licenses   Expires       Vendor
vxworks       2022.1     10          15-aug-2025   WR_DEAMON

How do I check Wind River license usage?

To view the users who are currently using the licenses:

lmutil.exe lmstat -S -c porta@nomeserver

Sample output:

Users of vxworks:  (Total of 10 licenses issued;  Total of 3 licenses in use)
  "vxworks" v2022.1, vendor: WR_DEAMON
  floating license
    user1 client01 (v2022.1) (windserver/27000 1050), start Tue 23/04 10:15

    user3 client03 (v2022.1) (windserver/27000 1052), start Tue 23/04 10:20
