########################## Auditbeat Configuration #############################

# This is a reference configuration file documenting all non-deprecated options
# in comments. For a shorter configuration example that contains only the most
# common options, please see auditbeat.yml in the same directory.

# Config reloading allows to dynamically load modules. Each file which is
# monitored must contain one or multiple modules as a list.

  # Period on which files under path should be checked for changes
  reload.period: 60s

# Maximum amount of time to randomly delay the start of a dataset. Use 0 to
# disable startup delay.

# ================================= Processors =================================
{{ elk_macros.beat_processors(processors) }}

# Processors are used to reduce the number of fields in the exported event or to
# enhance the event with external metadata. This section defines a list of
# processors that are applied one by one and the first one receives the initial
# event:
#
#   event -> filter1 -> event1 -> filter2 ->event2 ...
#
# The supported processors are drop_fields, drop_event, include_fields,
# decode_json_fields, and add_cloud_metadata.
#
# For example, you can use the following processors to keep the fields that
# contain CPU load percentages, but remove the fields that contain CPU ticks
# values:
#
#processors:
#  - include_fields:
#      fields: ["cpu"]
#  - drop_fields:
#      fields: ["cpu.user", "cpu.system"]

# The following example drops the events that have the HTTP response code 200:
#
#processors:
#  - drop_event:
#      when:
#        equals:
#          http.code: 200

#
#processors:
#  - rename:
#      fields:

# Tencent Cloud, and Alibaba Cloud.
#
#processors:

#
# The following example enriches each event with the machine's local time zone
# offset from UTC.
#
#processors:
#  - add_locale:
#      format: offset
#
# The following example enriches each event with docker metadata, it matches

#
#processors:
#  - add_docker_metadata: ~

# The following example enriches each event with host metadata.
#
#processors:

#
#processors:
#  - add_process_metadata:
