Hi @dahlberg
I Started with this, but If you know the field names maybe you could post them and I'll update my answer, but for now I have just called them a,b,c etc.

^(?P<a>[^\s]+)\s+(?P<b>[^\s]+)\s+(?P<c>[^\s]+)\s+(?P<d>[^\s]+)\s+(?P<e>[^\s]+)\s+(?P<f>[^\s]+)?\s+(?P<g>[^\s]+)?\s+(?P<h>[^\s]+)?\s+(?P<i>[^\s]+)\s+(?P<j>[^\s]+)\s+(?P<k>[^\s]+)\s+(?P<l>[^\s]+)
Obviously, not all fields may be present in all logs, so you may need to fiddle the the option flag ?
