###################### Filebeat Configuration Example #########################
?
# This file is an example configuration file highlighting only the most common
# options. The filebeat.reference.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:

?
# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.

# ============================== Filebeat inputs ===============================
?
filebeat.inputs:
?
# Each - is an input. Most options can be set at the input level, so
# you can use different inputs for various configurations.
# Below are the input specific configurations.
?
# filestream is an input for collecting log messages from files.

?
  # Exclude lines. A list of regular expressions to match. It drops the lines that are
  # matching any regular expression from the list.
  # Line filtering happens after the parsers pipeline. If you would like to filter lines
  # before parsers, use include_message parser.
