Configuration: Output (v0.12 style)

Here is a sample configuration for old fluentd v0.12. It works with fluentd v1 too but not recommended for it.

<match pattern>
  @type s3

  aws_key_id YOUR_AWS_KEY_ID
  aws_sec_key YOUR_AWS_SECRET_KEY
  s3_bucket YOUR_S3_BUCKET_NAME
  s3_region ap-northeast-1

  path logs/
  s3_object_key_format %{path}%{time_slice}_%{index}.%{file_extension}
  buffer_path /var/log/fluent/s3
  time_slice_format %Y%m%d-%H
  time_slice_wait 10m
  utc
  format json
</match>

If you want to embed tag in path / s3_object_key_format, you need to use fluent-plugin-forest plugin.

The following explanations are about the differences with v1. Other parameters are same with v1, see Configuration: Output for them.

format (for v0.12)

@format json
include_time_key true
time_key log_time # default is time

This parameter is for v0.12. Use <format> and <inject> for v1.

buffer_path (for v0.12)

path prefix of the files to buffer logs.

This parameter is for v0.12. Use <buffer>'s path in v1.

time_slice_format (for v0.12)

Format of the time used as the file name. Default is '%Y%m%d'. Use '%Y%m%d%H' to split files hourly.

This parameter is for v0.12. Use buffer placeholder for path / s3_object_key_format in v1.

time_slice_wait (for v0.12)

The time to wait old logs. Default is 10 minutes. Specify larger value if old logs may reach.

This parameter is for v0.12. Use <buffer>'s timekey_wait in v1.
