1. How to save all the message outputted on screen?
Generally, SLT just save the SLT log message(e.g. begin with SLT Info) into logfile.
To save all the message outputted, e.g. unexpected error message, you can use 'tee':
# runslt -D 2>&1 | tee mylog
And, you can sltparser 'mylog' to get the same result files.
# sltparser mylog
