As far as I know, using the regular regexp rules in graylog, there isn't a
way to tell it to just split on white space, and there isn't a way to tell
it to capture multiple values in one pattern.  Not with the interfaces we
have available, anyway.

In perl, I could do something like:
  ($field1,$field2,field3) = split(/\s+/, $logline);

I don't think the graylog system is nearly that powerful.

The first pattern I gave you extracts the contents of the first field.  The
^ specifies the pattern starts at the beginning of the line.  The (.+)\s
says to capture all characters and that it will end with a space.
Normally, .+ means 'match any character forever', but the rest of the
pattern has to match as well.  The rest of it, \d+/\d+/20\d+ will only
match on the date field.  So, by matching the date field there, we prevent
.+ from matching anything past the last space before the date, and so it
captures the entire sourceserver field.

sourceserver:  ^(.+)\s\d+/\d+/20\d\d\s+

I don't know anything about creating content packs.

I think if you really want to use regexp, you just need to find  yourself a
good tutorial and do some reading.  This sort of basic regular expression
tutoring is likely outside the scope of this group.

No matter what we think of Linux versus FreeBSD, etc., the one thing I
really like about Linux is that it has Microsoft worried. Anything
that kicks a monopoly in the pants has got to be good for something.
