Requirements: * Amazon S3 Bucket and S3 Access Permissions (Typically access_key_id and secret_access_key) * S3 PutObject permission S3 outputs create temporary files into the OS' temporary directory, you can specify where to save them using the `temporary_directory` option. S3 output files have the following format ls.s3.312bc026-2f5d-49bc-ae9f-5940cf4ad9a6.2013-04-18T10.00.tag_hello.part0.txt |======= | ls.s3 | indicate logstash plugin s3 | | 312bc026-2f5d-49bc-ae9f-5940cf4ad9a6 | a new, random uuid per file. | | 2013-04-18T10.00 | represents the time whenever you specify time_file. | | tag_hello | this indicates the event's tag. | | part0 | this means if you indicate size_file then it will generate more parts if your file.size > size_file. When a file is full it will be pushed to the bucket and then deleted from the temporary directory. If a file is empty, it is simply deleted. Empty files will not be pushed | |======= Crash Recovery: * This plugin will recover and upload temporary log files after crash/abnormal termination when using `restore` set to true #### Usage: This is an example of logstash config: [source,ruby] output { s3{ access_key_id => "crazy_key" (optional) secret_access_key => "monkey_access_key" (optional) region => "eu-west-1" (optional, default = "us-east-1") bucket => "your_bucket" (required) size_file => 2048 (optional) - Bytes time_file => 5 (optional) - Minutes codec => "plain" (optional) canned_acl => "private" (optional. Options are "private", "public-read", "public-read-write", "authenticated-read", "aws-exec-read", "bucket-owner-read", "bucket-owner-full-control", "log-delivery-write".

This plugin uses the AWS SDK and supports several ways to get credentials, which will be tried in this order: 1. Static configuration, using `access_key_id` and `secret_access_key` params in logstash plugin config 2. External credentials file specified by `aws_credentials_file` 3. Environment variables `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` 4. Environment variables `AMAZON_ACCESS_KEY_ID` and `AMAZON_SECRET_ACCESS_KEY` 5.

[id="plugins-{type}s-{plugin}-prefix"] ===== `prefix` * Value type is <> * Default value is `""` Specify a prefix to the uploaded filename, this can simulate directories on S3. Prefix does not require leading slash. This option supports logstash interpolation: https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html#sprintf; for example, files can be prefixed with the event date using `prefix = "%{+YYYY}/%{+MM}/%{+dd}"`.

If you have tags then it will generate a specific size file for every tags [id="plugins-{type}s-{plugin}-ssekms_key_id"] ===== `ssekms_key_id` * Value type is <> * There is no default value for this setting. The key to use when specified along with server_side_encryption => aws:kms. If server_side_encryption => aws:kms is set but this is not default KMS key is used. http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingKMSEncryption.html [id="plugins-{type}s-{plugin}-storage_class"] ===== `storage_class` * Value can be any of: `STANDARD`, `REDUCED_REDUNDANCY`, `STANDARD_IA` * Default value is `"STANDARD"` Specifies what S3 storage class to use when uploading the file.

If you define file_size you have a number of files in consideration of the section and the current tag. 0 stay all time on listerner, beware if you specific 0 and size_file 0, because you will not put the file on bucket, for now the only thing this plugin can do is to put the file when logstash restart.
