s3 output plugin buffers event logs in local file and upload it to S3 periodically.
This plugin splits files exactly by using the time of event logs (not the time when the logs are received). For example, a log ‘2011-01-02 message B’ is reached, and then another log ‘2011-01-03 message B’ is reached in this order, the former one is stored in “20110102.gz” file, and latter one in “20110103.gz” file.
Simply use RubyGems:
gem install fluent-plugin-s3
<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_endpoint s3-ap-northeast-1.amazonaws.com
s3_object_key_format {path}{time_slice}_{index}.{file_extension}
path logs/
buffer_path /var/log/fluent/s3
time_slice_format %Y%m%d-%H
time_slice_wait 10m
utc
</match>
- aws_key_id (required)
-
AWS access key id.
- aws_sec_key (required)
-
AWS secret key.
- s3_bucket (required)
-
S3 bucket name.
- s3_endpoint
-
s3 endpoint name. Example, Tokyo region is “s3-ap-northeast-1.amazonaws.com”.
- s3_object_key_format
-
The format of S3 object keys. You can use several built-in variables:
-
%{path}
-
%{time_slice}
-
%{index}
-
%{file_extension}
to decide keys dynamically.
%{path} is exactly the value of path configured in the configuration file. E.g., “logs/” in the example configuration above. %{time_slice} is the time-slice in text that are formatted with time_slice_format. %{index} is the sequential number starts from 0, increments when multiple files are uploaded to S3 in the same time slice. %{file_extention} is always “gz” for now.
The default format is “{path}{time_slice}_{index}.{file_extension}”.
For instance, using the example configuration above, actual object keys on S3 will be something like:
"logs/20130111-22_0.gz" "logs/20130111-23_0.gz" "logs/20130111-23_1.gz" "logs/20130112-00_0.gz"
With the configuration:
s3_object_key_format {path}/events/ts={time_slice}/events_{index}.{file_extension}
path log
time_slice_format %Y%m%d-%H
You get:
"log/events/ts=20130111-22/events_0.gz" "log/events/ts=20130111-23/events_0.gz" "log/events/ts=20130111-23/events_1.gz" "log/events/ts=20130112-00/events_0.gz"
- path
-
path prefix of the files on S3. Default is “” (no prefix).
- buffer_path (required)
-
path prefix of the files to buffer logs.
- time_slice_format
-
Format of the time used as the file name. Default is ‘%Y%m%d’. Use ‘%Y%m%d%H’ to split files hourly.
- time_slice_wait
-
The time to wait old logs. Default is 10 minutes. Specify larger value if old logs may reache.
- utc
-
Use UTC instead of local time.
