It should be something like this:
rex "(?<date_time>\d\d\/\d\d\/\d\d\d\d:\s\d\d:\d\d:\d\d\s\w{3}).*UI\sCMD_EXECUTED\s(?<cmd_executed>\d+)\s.*User\s(?<user>\w+)\s-\sRemote_ip\s(?<remote_ip>\d+\.\d+\.\d+\.\d+)"
It is always a good idea to use a regex tester, that are available in the web, to build your regex for the field extractions.
