Amazon Kinesis Data Streams

The Amazon Kinesis Data Streams output plugin allows to ingest your records into the Kinesis service.
This is the documentation for the core Fluent Bit Kinesis plugin written in C. It has all the core features of the aws/amazon-kinesis-streams-for-fluent-bit Golang Fluent Bit plugin released in 2019. The Golang plugin was named kinesis; this new high performance and highly efficient kinesis plugin is called kinesis_streams to prevent conflicts/confusion.
See here for details on how AWS credentials are fetched.
Configuration Parameters
Key
Description
region
The AWS region.
stream
The name of the Kinesis Streams Delivery stream that you want log records sent to.
time_key
Add the timestamp to the record under this key. By default the timestamp from Fluent Bit will not be added to records sent to Kinesis.
time_key_format
strftime compliant format string for the timestamp; for example, the default is '%Y-%m-%dT%H:%M:%S'. This option is used with time_key.
log_key
By default, the whole log record will be sent to Kinesis. If you specify a key name with this option, then only the value of that key will be sent to Kinesis. For example, if you are using the Fluentd Docker log driver, you can specify log_key log and only the log message will be sent to Kinesis.
role_arn
ARN of an IAM role to assume (for cross account access).
endpoint
Specify a custom endpoint for the Kinesis API.
sts_endpoint
Custom endpoint for the STS API.
auto_retry_requests
Immediately retry failed requests to AWS services once. This option does not affect the normal Fluent Bit retry mechanism with backoff. Instead, it enables an immediate retry with no delay for networking errors, which may help improve throughput when there are transient/random networking issues. This option defaults to true.
Getting Started
In order to send records into Amazon Kinesis Data Streams, you can run the plugin from the command line or through the configuration file:
Command Line
The kinesis_streams plugin, can read the parameters from the command line through the -p argument (property), e.g:
$ fluent-bit -i cpu -o kinesis_streams -p stream=my-stream -p region=us-west-2 -m '*' -f 1
Configuration File
In your main configuration file append the following Output section:
[OUTPUT]
    Name  kinesis_streams
    Match *
    region us-east-1
    stream my-stream
Permissions
The following AWS IAM permissions are required to use this plugin:
{
	"Version": "2012-10-17",
	"Statement": [{
		"Effect": "Allow",
		"Action": [
			"kinesis:PutRecords"
		],
		"Resource": "*"
	}]
}
Worker support
Fluent Bit 1.7 adds a new feature called workers which enables outputs to have dedicated threads. This kinesis_streams plugin fully supports workers.
Example:
[OUTPUT]
    Name  kinesis_streams
    Match *
    region us-east-1
    stream my-stream
    workers 2
If you enable a single worker, you are enabling a dedicated thread for your Kinesis output. We recommend starting with without workers, evaluating the performance, and then adding workers one at a time until you reach your desired/needed throughput. For most users, no workers or a single worker will be sufficient.
AWS for Fluent Bit
Amazon distributes a container image with Fluent Bit and these plugins.
GitHub

Amazon ECR Public Gallery
​aws-for-fluent-bit​
Our images are available in Amazon ECR Public Gallery. You can download images with different tags by following command:
docker pull public.ecr.aws/aws-observability/aws-for-fluent-bit:<tag>
For example, you can pull the image with latest version by:
docker pull public.ecr.aws/aws-observability/aws-for-fluent-bit:latest
If you see errors for image pull limits, try log into public ECR with your AWS credentials:
aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws
You can check the Amazon ECR Public official doc for more details.
