Bothan

A simple platform for publishing metrics, both as JSON, and as embeddable visualisations and dashboards.

Bothan was an experiment by the ODI. As of 2019, Bothan is no longer maintained, but this source code remains available, as well as tutorials on deploying your personal instance of Bothan to Heroku and intergrating with Zapier

There are also two software libraries that make interfacing with Bothan super easy:

Summary of features

Bothan is a Sinatra web app that provides a simple wrapper around MongoDB to allow storage of time series metrics. Bothan provides a REST API for storing and retrieving time-series data, as well as human-readable views which can be customised and embedded in other sites, allowing it to be used for building dashboards. It is designed for open publication of metrics data and includes licensing metadata for simple generation of an Open Data Certificate Read the Documentation for the API here

Deploy

Follow the public feature roadmap for Bothan

Upgrading

Most updates should not require intervention, but manual steps are occasionally required. If you are experiencing deployment problems, see the upgrade guide.

Development

Requirements

ruby version 2.3.0p0

The application uses mongodb for data persistence

The application requires capybara-webkit for testing (for install instuctions see below)

Environment variables

METRICS_API_USERNAME=foo
METRICS_API_PASSWORD=bar
METRICS_API_TITLE='ODI Metrics'
METRICS_API_DESCRIPTION='This API contains a list of all metrics collected by the Open Data Institute since 2013'
METRICS_API_LICENSE_NAME='Creative Commons Attribution-ShareAlike'
METRICS_API_LICENSE_URL='https://creativecommons.org/licenses/by-sa/4.0/'
METRICS_API_PUBLISHER_NAME='Open Data Institute'
METRICS_API_PUBLISHER_URL='http://theodi.org'
METRICS_API_CERTIFICATE_URL='https://certificates.theodi.org/en/datasets/213482/certificate'
PUSHER_URL=

See below for Pusher configuration instructions

Specific Development Instructions

Pusher setup
  1. Log in to https://pusher.com
  2. Create a new application and call it something sensible
  3. Select the App Keys tab and note the following values
PUSHER_APP_ID=
PUSHER_KEY=
PUSHER_SECRET=

You can create the PUSHER_URL variable required for your .env file by concatenating the above variables as follows: PUSHER_KEY:PUSHER_SECRET@api-eu.pusher.com/apps/PUSHER_APP_ID

Capybara

To run bothan locally requires capybara-webkit. Specific instructions to get this running is as follows

https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#homebrew

At present Capybara depends on Qt 5. This requires the full Xcode, rather than xcode developer tools, to be installed

Database Configuration

Install mongo:
brew install mongo redis (if using brew)

make a data directory for mongo databases
sudo mkdir -p /data/db

change directory ownership so that mongodb can operate
sudo chown -R $USERNAME /data/

Development: Running the full application locally

Checkout the repository

run mongod to establish a database for persistence

run brew install cmake or sudo apt-get install cmake

run bundle in the checked out directory.

optional: run rake demo:setup to establish some demo metrics for use locally

The app is loaded via Rack Middleware.
execute bundle exec rackup config.ru to start the application

Tests

A MongoDB instance must be running prior to executing test suites (see steps above from Running the full application locally for installation)

Execute mongod

The entire suite of unit tests (rspec) and user features (cucumber) can be executed with the rake command

alternatively execute each suite separately with

  • for unit tests execute bundle exec rspec
  • for Cucumber features execute bundle exec cucumber

Rake Tasks

rake demo:setup will establish one metric of each type that Bothan supports

Deployment

Deployment On Heroku

Bothan can deploy a personal instance to Heroku.

You can employ this as an alternative to running a full local dev instance if you couple your heroku instance with the heroku toolbelt.
