config_logstash_http_input_ipv6.yml

# The grok_exporter is capable of receive log entries from webhook sources.
#
# This input configuration example demonstrates how to configure grok_exporter
#   to receive HTTP webhooks from the Logstash HTTP Output Plugin configured in
#   "json_batch" mode, which allows the transmission of multiple json log
#   entries in a single webhook.
#   https://www.elastic.co/guide/en/logstash/current/plugins-outputs-http.html
#
# The grok_exporter supports webhook reception in various formats.  Plain-text
#   or JSON, single entries or bulk entries.  To learn more, read the comments
#   in this example, and review the webhookTeailer_test.go unit tests.

input:

  type: webhook

  # HTTP Path to POST the webhook
  # Default is `/webhook`
  webhook_path: /webhook

  # HTTP Body POST Format
  # text_single: Webhook POST body is a single plain text log entry
  # text_bulk: Webhook POST body contains multiple plain text log entries
  #   separated by webhook_text_bulk_separator (default: \n\n)
  # json_single: Webhook POST body is a single json log entry.  Log entry
  #   text is selected from the value of a json key determined by
  #   webhook_json_selector.
  # json_lines: Webhook POST body contains multiple json log entries, with
  #   newline-separated log lines holding an individual json object. JSON
  #   object itself may not contain newlines. For example:
  #   example:
  #       { app="foo", stage="prod", log="example log message" }
  #       { app="bar", stage="dev", log="another line" }
  #   Log entry text is selected from the value of a json key determined
  #   by webhook_json_selector.
  # json_bulk: Webhook POST body contains multiple json log entries.  The
  #   POST body envelope must be a json array "[ <entry>, <entry> ]".  Log
  #   entry text is selected from the value of a json key determined by
  #   webhook_json_selector.
  # Default is `text_single`
  webhook_format: json_bulk

  # JSON Path Selector
  # Within an json log entry, text is selected from the value of this json selector
  #   Example ".path.to.element"
  # Default is `.message`
  webhook_json_selector: .message

  # Bulk Text Separator
  # Separator for text_bulk log entries
  # Default is `\n\n`
  webhook_text_bulk_separator: "\n\n"
