[mm12]

I have a log file below format and props.conf wriiten below. I am getting first four lines as one event and the remaining lines as separate events. But I want as single event . Can anyone help me on this.

The BREAK_ONLY_BEFORE_DATE separates events at dates so it should be no surprise that each line is a new event.

Try these settings to get the whole set into a single event.

LINE_BREAKER = ([\r\n]+)product =
SHOULD_LINEMERGE = true
MAX_TIMESTAMP_LOOKAHEAD = 18
TIME_FORMAT = %d/%m/%y %H:%M:%S:%3N %Z
TIME_PREFIX = ^\[
TRUNCATE = 0

Thanks. I have tried that still I am not getting as single event

Just noticed SHOULD_LINEMERGE should be "false", though it may not make much difference.
