If you always have "PDR Message Listener" before the status value you want to capture, try this

your base search | rex "PDR Message Listener Completed (?<status>\s+)"

If the string before status value is not constant but always 3 words, then try this

your base search | rex "^(\w+\s){3}(?<status>\s+)"

I think the capture group should be (?<status>\w+) and not use \s+, right?

edit: formatting

or if you want to use \s then it should be "^(\w+\s){3}(?<status>[^\s]+)"
