Description

edit

Receive events through an AWS Kinesis stream.

This input plugin uses the Java Kinesis Client Library underneath, so the documentation at https://github.com/awslabs/amazon-kinesis-client will be useful.

AWS credentials can be specified either through environment variables, or an IAM instance role. The library uses a DynamoDB table for worker coordination, so you’ll need to grant access to that as well as to the Kinesis stream. The DynamoDB table has the same name as the application_name configuration option, which defaults to "logstash".

The library can optionally also send worker statistics to CloudWatch.

This plugin supports the following configuration options plus the Common Options described later.

Setting Input type Required

application_name

checkpoint_interval_seconds

number

No

kinesis_stream_name

string

string, one of [nil, "cloudwatch"]

No

region

No

profile

string

No

Also see Common Options for a list of options supported by all input plugins.

 

application_name

edit
  • Value type is string
  • Default value is "logstash"

The application name used for the dynamodb coordination table. Must be unique for this kinesis stream.

checkpoint_interval_seconds

edit
  • Value type is number
  • Default value is 60

How many seconds between worker checkpoints to dynamodb.

kinesis_stream_name

edit
  • This is a required setting.
  • Value type is string
  • There is no default value for this setting.

The kinesis stream name.

metrics

edit
  • Value can be any of: ``, cloudwatch
  • Default value is nil

Worker metric tracking. By default this is disabled, set it to "cloudwatch" to enable the cloudwatch integration in the Kinesis Client Library.

region

edit
  • Value type is string
  • Default value is "us-east-1"

The AWS region for Kinesis, DynamoDB, and CloudWatch (if enabled)

profile

edit
  • Value type is string
  • Default value is nil

The AWS profile name for authentication. This ensures that the ~/.aws/credentials AWS auth provider is used. By default this is empty and the default chain will be used.

Details

edit

 

add_field

edit
  • Value type is hash
  • Default value is {}

Add a field to an event

codec

edit
  • Value type is codec
  • Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

enable_metric

edit
  • Value type is boolean
  • Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

  • Value type is string
  • There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 kinesis inputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

input {
  kinesis {
    id => "my_plugin_id"
  }
}

tags

edit
  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

type

edit
  • Value type is string
  • There is no default value for this setting.

This is the base class for Logstash inputs. Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
