LDRA Test tools: Using lmutil for license diagnostics

Several commands can help identify the source of a licensing issue. The FlexLM utilities include an executable called lmutil, which can be used to display license availability and diagnostic information.

To check the availability of a specific feature, use:

lmutil lmstat -f <FEATURE>

For example, to check usage of the LDRALAUNCHER feature:

lmutil lmstat -f LDRALAUNCHER

This produces output similar to the following:
