Understanding the V-Ray License Server
The V-Ray license server (OLS) shows the status of your V-Ray licences, and is the same for whichever V-Ray product(s) you have.
Go to localhost:30304 in your web browser to find the licence server if it is installed on your computer.
Licence types will be shown as blocks in the main area. Clicking on these blocks will show the total number of licences, those currently 'available' and those already 'in use'.
