The trace/log of the CTT is collected in the user interface and can be saved in a file from there. But in Linux and when running the CTT from the command line, there is no enhanced logging/tracing available. This makes investigations of issues difficult.

The CTT should automatically save the log/trace in a file so it is accessible even without using the user interface. Also the return parameters are currently -1, 0 and 1. It potentially would make sense to use other negative values to indicate common issues like wrong parameter strings or other issues during the startup or execution of the executable.
