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.
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 |
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. |
In order to send records into Amazon Kinesis Data Streams, you can run the plugin from the command line or through the configuration file:
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
In your main configuration file append the following Output section:
[OUTPUT]Name kinesis_streamsMatch *region us-east-1stream my-stream
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_streamsMatch *region us-east-1stream my-streamworkers 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.
Amazon distributes a container image with Fluent Bit and these plugins.

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
