Enter Host Name, Name the session, Go to Logging Option in the left top corner, select all sessions, provide log file name and location,
go back to Session tab, click on the save button. Done, you have saved a session
Now open CMD and write the command as below enter image description here

You are done. Every time this session is invoked, the commands and output will be logged. Hope this helps.
