Description
editYou can use this plugin to receive events through AWS Kinesis. This plugin uses the Java Kinesis Client Library. 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.
Usage
editinput { kinesis { kinesis_stream_name => "my-logging-stream" codec => json { } } }
Using with CloudWatch Logs
editIf you want to read a CloudWatch Logs subscription stream, you’ll also need to install and configure the CloudWatch Logs Codec.
Authentication
editThis plugin uses the default AWS SDK auth chain,
DefaultAWSCredentialsProviderChain,
to determine which credentials the client will use, unless profile
is set, in
which case
ProfileCredentialsProvider
is used.
The default chain reads the credentials in this order:
-
AWS_ACCESS_KEY_ID
/AWS_SECRET_KEY
environment variables -
~/.aws/credentials
credentials file - EC2 instance profile
The credentials need access to the following services:
- AWS Kinesis
- AWS DynamoDB. The client library stores information for worker coordination in DynamoDB (offsets and active worker per partition)
- AWS CloudWatch. If the metrics are enabled the credentials need CloudWatch update permissions granted.
See the AWS documentation for more information on the default chain.

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.
http_proxy
edit- Value type is password
- There is no default value for this setting.
Proxy support for Kinesis, DynamoDB, and CloudWatch (if enabled).
initial_position_in_stream
edit- Value type is string
-
Default value is
"TRIM_HORIZON"
The value for initialPositionInStream. Accepts "TRIM_HORIZON" or "LATEST".
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.
non_proxy_hosts
edit- Value type is string
- There is no default value for this setting.
Hosts that should be excluded from proxying, separated by the "|" (pipe) character.
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.
additional_settings
edit- Value type is string
- There is no default value for this setting
The KCL provides several configuration options which can be set in
KinesisClientLibConfiguration.
These options are configured via various function calls that all begin with
with
. Some of these functions take complex types, which are not supported.
However, you may invoke any one of the withX()
functions that take a primitive
by providing key-value pairs in snake_case
.
Example:
To set the dynamodb read and write capacity values, use these functions:
withInitialLeaseTableReadCapacity
and withInitialLeaseTableWriteCapacity
.
additional_settings => {"initial_lease_table_read_capacity" => 25 "initial_lease_table_write_capacity" => 100}
Common options

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" } }
Variable substitution in the id
field only supports environment variables
and does not support the use of values from the secret store.
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.
