Data Import from REST API on Heroku

This article describes how to run td-agent on Heroku. td-agent is a data-import daemon for Treasure Data Hadoop. Although td-agent itself can accept data from various sources, the Heroku platform’s limitations cause td-agent to only accept HTTP input.

Heroku CLI setup

The heroku-td CLI plugin is also required as a bridge between the heroku CLI and the td CLI. Once you install the CLI plugin, you will be able to execute the heroku td family of commands.

$ heroku plugins:install
$ heroku td
usage: heroku td [options] COMMAND [args]
Please make sure to use the Heroku toolbelt. On December 1, 2012, Heroku stopped releasing new updates to the heroku gem. We have also stopped supporting the heroku gem.

Create Your App

You’re now ready to set up td-agent as a separate Heroku application. td-agent will become your central log aggregation server. We provide a boilerplate repository to get you started.

Follow the steps below to create td-agent as a Heroku application.

# Clone
$ git clone git://
$ cd heroku-td-agent
$ rm -fR .git
$ git init
$ git add .
$ git commit -m 'initial commit'

# Create the app & deploy
$ heroku create --stack cedar
$ git push heroku master

# Enable Addon
$ heroku addons:add treasure-data

# Confirm your API key
$ heroku td apikey:show

# Set your API key
$ vi td-agent.conf
$ git commit -a -m 'update apikey'

# Deploy
$ git push heroku master


You can now confirm that the log aggregation server is set up correctly. In the example below, you will send a GET request to the log server at to log the event { "json": "message" } in sample_table in sample_db. Note how the JSON-formatted data is passed as a query parameter value.

$ curl ""

$ curl ""

In general, the format is


Once you have sent the GET request, run the command heroku td tables to confirm that data is getting uploaded successfully.

$ heroku td tables
| Database         | Table         | Type | Count | Schema |
| sample_db        | sample_table  | log  | 1     |        |
1 rows in set

Logs are uploaded every 5 minutes.
