# The scheme to define a custom filter is:

# ```

#
# = fluentd filter type =
# This is the fluentd filter that the user wants to use for record manipulation.
#
# = definition of the fluentd filter =
# This defines the body/logic for using the filter for record manipulation.
#
# For example if you want to define a filter which sets cluster_name field to "my_awesome_cluster" you would the following filter
# <filter tail.containers.**>
# @type jq_transformer
# jq '.record.cluster_name = "my_awesome_cluster" | .record'
# </filter>

# type: jq_transformer
# body: jq '.record.cluster_name = "my_awesome_cluster" | .record'
# ```

# regexp: "<regexp_to_extract_timestamp_from_log>"
# format: "<format_of_the_timestamp>"
# multiline:
# firstline: "<regexp_to_detect_firstline_of_multiline>"
# flushInterval: 5s
# sourcetype: "<sourcetype_of_logs>"
# ```
#
# = <source> =
# It supports 3 kinds of sources: journald, file, and container.
# For `journald` logs, `unit` is required for filtering using _SYSTEMD_UNIT, example:
# ```
# docker:
# from:
# journald:
# unit: docker.service
# ```
#
# For `file` logs, `path` is required for specifying where is the log files. Log files are expected in `/var/log`, example:
# ```
# docker:
# from:
# file:
# path: /var/log/docker.log
# ```
#
# For `container` logs, `pod` field is required. It represents part of
# the pod name, can be name of a deployment or replica set. Use "*" to
# apply the configuration to all pods. Optional `container` value can be
# used to apply configuration to a particular container.
# ```
# kube-apiserver:

# pod: kube-apiserver
#
# etcd:
# from:
# pod: etcd-server
# container: etcd-container
# ```
#
# = timestamp =
# `timestampExtraction` defines how to extract timestamp from logs. This *only* works for `file` source.
# To use `timestampExtraction` you need to define both:
# - `regexp`: the Regular Expression used to find the timestamp from a log entry.
# The timestamp part must be in a `time` named group. E.g.
# (?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2})
# - `format`: a format string defintes how to parse the timestamp, e.g. "%Y-%m-%d %H:%M:%S".
# More details can be find: http://ruby-doc.org/stdlib-2.5.0/libdoc/time/rdoc/Time.html#method-c-strptime
#
# = multiline =
# `multiline` options provide basic multiline support. Two options:
# - `firstline`: a Regular Expression used to detect the first line of a multiline log.
# - `flushInterval`: The interval between data flushes, default value: 5s.
#
# = sourcetype =
# sourcetype of each kind of log can be defined using the `sourcetype` field.
# If `sourcetype` is not defined, `name` will be used.
#
# ---
# Here we have some default timestampExtraction and multiline settings for kubernetes components.
# So, usually you just need to redefine the source of those components if necessary.
