Amazon Kinesis Output for Telegraf

This is an experimental plugin that is still in the early stages of development. It will batch up all of the Points in one Put request to Kinesis. This should save the number of API requests by a considerable level.

About Kinesis

This is not the place to document all of the various Kinesis terms however it maybe useful for users to review Amazons official documentation which is available here.

Amazon Authentication

This plugin uses a credential chain for Authentication with the Kinesis API endpoint. In the following order the plugin will attempt to authenticate.

1. IAMS Role
2. Environment Variables
3. Shared Credentials

Config

For this output plugin to function correctly the following variables must be configured.

• region
• streamname
• partitionkey

region

The region is the Amazon region that you wish to connect to. Examples include but are not limited to

• us-west-1
• us-west-2
• us-east-1
• ap-southeast-1
• ap-southeast-2

streamname

The streamname is used by the plugin to ensure that data is sent to the correct Kinesis stream. It is important to note that the stream MUST be pre-configured for this plugin to function correctly. If the stream does not exist the plugin will result in telegraf exiting with an exit code of 1.

partitionkey

This is used to group data within a stream. Currently this plugin only supports a single partitionkey. Manually configuring different hosts, or groups of hosts with manually selected partitionkeys might be a workable solution to scale out.

format

The format configuration value has been designated to allow people to change the format of the Point as written to Kinesis. Right now there are two supported formats string and custom.

string

String is defined using the default Point.String() value and translated to []byte for the Kinesis stream.

custom

Custom is a string defined by a number of values in the FormatMetric() function.
