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.
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.
This plugin uses a credential chain for Authentication with the Kinesis API endpoint. In the following order the plugin will attempt to authenticate.
- Assumed credentials via STS if
role_arn
attribute is specified (source credentials are evaluated from subsequent rules) - Explicit credentials from
access_key
,secret_key
, andtoken
attributes - Shared profile from
profile
attribute - Environment Variables
- Shared Credentials
- EC2 Instance Profile
For this output plugin to function correctly the following variables must be configured.
- region
- streamname
- partitionkey
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
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.
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.
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 is defined using the default Point.String() value and translated to []byte for the Kinesis stream.
Custom is a string defined by a number of values in the FormatMetric() function.
