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.

Kinesis Input Configuration Options

edit

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

Setting	Input type	Required
`application_name`	string	No
`checkpoint_interval_seconds`	number	No
`kinesis_stream_name`	string	Yes
`metrics`	string, one of `[nil, "cloudwatch"]`	No
`profile`	string	No
`region`	string	No
`role_arn`	string	No
`role_session_name`	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.

`profile`

edit

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

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.

`region`

edit

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

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

`role_arn`

edit

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

The AWS role to assume. This can be used, for example, to access a Kinesis stream in a different AWS account. This role will be assumed after the default credentials or profile credentials are created. By default this is empty and a role will not be assumed.

`role_session_name`

edit

Value type is string
Default value is logstash

Session name to use when assuming an IAM role. This is recorded in CloudTrail logs for example.

Common Options

edit

The following configuration options are supported by all input plugins:

Setting	Input type	Required
`add_field`	hash	No
`codec`	codec	No
`enable_metric`	boolean	No
`id`	string	No
`tags`	array	No
`type`	string	No

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.

`id`

edit

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.

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.
