Cyclotron

📻 News and updates

Cyclotron is no longer being maintained. The tech stack is over a decade old and has not aged well, so it basically needs a complete rewrite to modernize it. Feel free to fork and continue development.

About

Cyclotron is a browser-based platform for creating dashboards. It provides standard boilerplate and plumbing, allowing non-programmers to easily create and edit dashboards using customizable components. It has a built-in dashboard editor, and hosts the dashboards directly.

Dashboards are defined declaratively as a JSON document, which contains all the properties required to render the Dashboard.

Contents

Key Concepts

  • Dashboard: a series of Pages, as well as Data Sources, Scripts, Styles, and other configurations; stored as a JSON document, it contains all the properties required to render itself

  • Page: one or more Widgets combined in various sizes and layout; one Page is displayed at a time

  • Widget: reusable component that displays on the Dashboard; different types are available

  • Data Source: reusable component that retrieves data for use by Widgets; different types are available

Features

  • Declarative definition of Dashboards, requiring no HTML or JavaScript (although it's optionally available)

  • Included Widgets: Annotation Chart, Chart, Header, HTML, iFrame, Image, Javascript, JSON, Number, QRCode, Stoplight, Table, Treemap, Youtube

  • Included Data Sources: CyclotronData, Elasticsearch, Graphite, InfluxDB, Javascript, JSON, Prometheus, Splunk

  • Built-in data loading, filtering, and sorting

  • LDAP/Active Directory Integration

  • Permissions for viewing and editing Dashboards

  • Built-in analytics for Dashboards

  • Mobile support

  • REST API access

Should I Use Cyclotron?

Cyclotron is best thought of as an alternative to custom, light-weight websites that visualize data. It provides the web hosting, page layout, data loading, and assorted widgets—all without writing code. In contrast, building a comparable website from scratch would require provisioning a server/VM, choosing the appropriate web frameworks and libraries, and writing the code for the site. Cyclotron simplifies this process dramatically, making it ideal for rapid prototyping.

However, Cyclotron has a limited set of built-in Widgets and Data Sources. The HTML and JavaScript Widgets do allow for a wide degree of customization, but require some web development. Cyclotron lacks built-in interactivity, so it may not be ideal for building highly interactive websites. Additionally, it is designed for building full-screen dashboards, not reports.

In regards to data, Cyclotron does not store or cache any data for Dashboards. Dashboards can load external data through various Data Sources, but it is done on-the-fly when Dashboards are viewed. Cyclotron can do filtering/sorting and custom transformations, but this should not be considered a replacement for ETL jobs. In this regard, Cyclotron is ideal as a front-end for an existing database or web service.

Requirements

  • Node.js
    • Requires >= 6.x to run cyclotron-site tests
    • Requires >= 0.10 to run
  • MongoDB (2.6+)
  • (Optional) Any web server--Nginx, Apache, IIS, etc

Node.js and MongoDB are available on Linux, OS X, and Windows, so it should be possible to run Cyclotron on any of these platforms, although the specific steps may vary.

MongoDB 2.6 or above is required to use all functionality of the service.

Installation

These installation instructions are primarily intended for development and testing purposes. Refer to the Deployment section for more details on server deployment.

Start by cloning this git repository locally onto your computer. If you don't have git installed, GitHub has a nice guide: Set Up Git. On Windows, GitHub for Windows is an easy way to install git.

Alternatively, download a ZIP archive of the repository contents and extract it.

MongoDB

Install MongoDB according to the installation instructions for your system. Cyclotron automatically creates the MongoDB database on startup MongoDB server, so no other configuration needs to be done.

MongoDB does not have to be installed on the same system as the Cyclotron website or service, as long as the connection property is updated accordingly. Replica sets and authentication are also supported.

Ensure MongoDB is running before continuing:

mongod --config /usr/local/etc/mongod.conf

Node.js

Install the latest stable version of Node.js for your system. This should install npm as well.

Packages may be available separately for your system, depending on the OS and package manager.

REST API

The cyclotron-svc/ folder contains the REST API for Cyclotron, which interfaces with MongoDB.

  1. Open the cyclotron-svc/ folder in the shell

  2. Install dependencies using npm:

     npm install

    Windows: this may need to be run as an Administrator. Open the Node.js Command Prompt as an Administrator and run the command there.

    Windows/OSX/Linux: node-gyp may require certain dependencies to be installed. See platform-specific instructions here.

  3. Create a configuration file at cyclotron-svc/config/config.js. A sample configuration file sample.config.js is provided:

     cp config/sample.config.js config/config.js

    The sample config defaults to using a local MongoDB instance, with authentication disabled. If using a remote MongoDB server or cluster, update the mongodb property accordingly.

    If using Active Directory or LDAP, ensure that the property enableAuth is set to true, and that all the ldap properties are filled in correctly, including the service account username and password used to validate logins.

  4. Start the service in node:

     node app.js

  5. To verify the service is running, open the API documentation in a browser at http://localhost:8077

For more information on the REST API and its configuration, please refer to cyclotron-svc/README.md.

Website

The cyclotron-site/ folder contains the website for Cyclotron.

  1. Open the cyclotron-site/ folder in the shell

  2. Install all dependencies using npm:

     npm install

    Windows: this may need to be run as an Administrator. Open the Node.js Command Prompt as an Administrator and run the command there.

  3. Install Gulp globally. This is the build system for the website, and only has to be done once.

     npm install --global gulp

    Windows/Linux/OSX: this may need to be run as an Administrator or with sudo privileges.

  4. Build and run the service:

     gulp server

    This compiles the website into the _public folder and starts a local development web server. The website should automatically open: http://localhost:8080.

    "unable to connect to github.com": this may be due to a firewall blocking the git:// protocol. Run this:

     git config --global url."https://".insteadOf git://

    Windows: Git must be in the PATH to successfully build the website; if using GitHub for Windows, just open the Git Shell which automatically adds it.

  5. Update the configuration file at _public/js/conf/configService.js as needed. Gulp automatically populates this file from sample.configService.js if it does not exist.

    The sample config defaults to using a local cyclotron-svc instance, with authentication disabled. If authentication has been enabled in the REST API, it must be enabled in this config as well.

For more information on the Cyclotron website, please refer to cyclotron-site/README.md.

Docker

A Dockerfile and docker-compose.yml example can be found here: https://github.com/baumandm/cyclotron-docker.

Deployment

For specific details on deployment, please refer to cyclotron-site/README.md and cyclotron-svc/README.md.
