Multiline

multiline:
# Sticks together all lines
# that don’t start with a [
pattern: ^\[
negate: true
match: after
Filebeat extra power
• Sticks together related log lines in a
single event
• For all those long exceptions
• Can also be done by Logstash, but it’s
sometimes easier to configure the
patterns closer to the source
