s3

Overview

s3 is a source plugin that reads events from Amazon Simple Storage Service (S3) (Amazon S3) objects. The following table describes options you can use to configure the s3 source.

Option Required Type Description
notification_type Yes String Must be sqs.
compression No String The compression algorithm to apply: none, gzip, or automatic. Default value is none.
codec Yes Codec The codec to apply. Must be newline, json, or csv.
sqs Yes sqs The Amazon Simple Queue Service (SQS) (Amazon SQS) configuration. See sqs for details.
aws Yes aws The AWS configuration. See aws for details.
on_error No String Determines how to handle errors in Amazon SQS. Can be either retain_messages or delete_messages. If retain_messages, then Data Prepper will leave the message in the Amazon SQS queue and try again. This is recommended for dead-letter queues. If delete_messages, then Data Prepper will delete failed messages. Default value is retain_messages.
buffer_timeout No Duration The amount of time allowed for for writing events to the Data Prepper buffer before timeout occurs. Any events that the Amazon S3 source cannot write to the buffer in this time will be discarded. Default value is 10 seconds.
records_to_accumulate No Integer The number of messages that accumulate before writing to the buffer. Default value is 100.
metadata_root_key No String Base key for adding S3 metadata to each Event. The metadata includes the key and bucket for each S3 object. Defaults to s3/.
disable_bucket_ownership_validation No Boolean If true, the S3Source will not attempt to validate that the bucket is owned by the expected account. The expected account is the same account that owns the Amazon SQS queue. Defaults to false.

sqs

The following parameters allow you to configure usage for Amazon SQS in the s3 source plugin.

Option Required Type Description
queue_url Yes String The URL of the Amazon SQS queue from which messages are received.
maximum_messages No Integer The maximum number of messages to receive from the Amazon SQS queue in any single request. Default value is 10.
visibility_timeout No Duration The visibility timeout to apply to messages read from the Amazon SQS queue. This should be set to the amount of time that Data Prepper may take to read all the Amazon S3 objects in a batch. Default value is 30s.
wait_time No Duration The amount of time to wait for long polling on the Amazon SQS API. Default value is 20s.
poll_delay No Duration A delay to place between reading/processing a batch of Amazon SQS messages and making a subsequent request. Default value is 0s.

aws

Option Required Type Description
region No String The AWS Region to use for credentials. Defaults to standard SDK behavior to determine the Region.
sts_role_arn No String The AWS Security Token Service (AWS STS) role to assume for requests to Amazon SQS and Amazon S3. Defaults to null, which will use the standard SDK behavior for credentials.

file

Source for flat file input.

Option Required Type Description
path Yes String The path to the input file (e.g. logs/my-log.log).
format No String The format of each line in the file. Valid options are json or plain. Default value is plain.
record_type No String The record type to store. Valid options are string or event. Default value is string. If you would like to use the file source for log analytics use cases like grok, set this option to event.

pipeline

Source for reading from another pipeline.

Option Required Type Description
name Yes String Name of the pipeline to read from.

Metrics

The s3 processor includes the following metrics.

Counters

  • s3ObjectsFailed: The number of Amazon S3 objects that the s3 source failed to read.
  • s3ObjectsNotFound: The number of Amazon S3 objects that the s3 source failed to read due to an Amazon S3 "Not Found" error. These are also counted toward s3ObjectsFailed.
  • s3ObjectsAccessDenied: The number of Amazon S3 objects that the s3 source failed to read due to an "Access Denied" or "Forbidden" error. These are also counted toward s3ObjectsFailed.
  • s3ObjectsSucceeded: The number of Amazon S3 objects that the s3 source successfully read.
  • sqsMessagesReceived: The number of Amazon SQS messages received from the queue by the s3 source.
  • sqsMessagesDeleted: The number of Amazon SQS messages deleted from the queue by the s3 source.
  • sqsMessagesFailed: The number of Amazon SQS messages that the s3 source failed to parse.

Timers

  • s3ObjectReadTimeElapsed: Measures the amount of time the s3 source takes to perform a request to GET an S3 object, parse it, and write events to the buffer.
  • sqsMessageDelay: Measures the amount of time from when Amazon S3 creates an object to when it is fully parsed.

Distribution summaries

  • s3ObjectSizeBytes: Measures the size of Amazon S3 objects as reported by the Amazon S3 Content-Length. For compressed objects, this is the compressed size.
  • s3ObjectProcessedBytes: Measures the bytes processed by the s3 source for a given object. For compressed objects, this is the uncompressed size.
  • s3ObjectsEvents: Measures the number of events (sometimes called records) produced by an Amazon S3 object.
