What configuration(s) have you tried? How would you like to see the log parsed, i.e. what fields do you want to extract?

csv {
skip_empty_columns => "true"
separator => " "
columns => ["#timeStamp","HTTPMethod","NUMBER","username","timetaken","Request"]
}

How to grok/filter different lines, since the format is different for each line ?

4

You could e.g. use a conditional to check which format the current line has and pick one of two sets of filters.

Or, instead of csv use a single grok filter with two expressions, one for each kind of log message. Logstash will try both expressions (if necessary).
