  FnordMetric is a framework for collecting and displaying timseries data. It is split up into

  three components:

  FnordMetric UI

  --------------

  FnordMetric UI is a HTML5 / JavaScript API that lets you plugin realtime data and timeseries

  graphs into any webpage without having to write a single line of code. It gives you maximum

  flexiblitiy as you can control the complete layout and style with HTML and CSS. FnordMetric UI

  uses WebSockets to communicate with the backend. There are two backend implementations:

  FnordMetric Classic (ruby + redis) or FnordMetric Enterprise (JVM). You can use FnordMetric UI

  as a white label solution to power your custom realtime analytics apps.

  FnordMetric Classic

  -------------------

  FnordMetric Classic offers a ruby DSL for processing data streams and manipulating gauges that

  get stored in redis. It includes a collection of pre-made UI widgets which you can use to build

  beautiful web dashboards within minutes. You can also use the FnordMetric UI HTML5 API to display

  the data on another website or build highly customized / white label views.

  FnordMetric Enterprise

  ----------------------

  FnordMetric Enterprise is a JVM based timeseries database which serves as a backend for FnordMetric

  UI. It does not offer it's own user interface.

  The basic concept in FnordMetric is called a "gauge". A Gauge is a primitive data store for a numerical value over

  time. A gauge has two dimensions: Value und Time. Gauges can be used in different modes like sum,

  average, max/min, etcetara.

  The FnordMetric core deals with processing data. There are two basic concepts:

  events and gauges.

  An Event is a piece of data that is sent to FnordMetric through one of the various

  sources. This event is a JSON Object / Hash with almost no constraints on the schema.

  A Gauge is a primitive data store for a numerical value over time (basically a counter

  with history). Gauges can be used in different modes like sum, average, max/min, etcetara.

  You write event handlers in ruby that get invoked per incoming event and modify (increment,

  set, etcetera) gauges.

  FnordMetric offers ways to display these gauges:

  FnordMetric Embed (recommended): FnordMetric Embed is a JavaScript library that provides a HTML5 API

  which lets you plugin realtime data and timeseries graphs into any webpage without having

  to write any code. This gives you a lot of flexiblitiy as you can control the complete

  layout and style with HTML and CSS. You can FnordMetric Embed as a white label solution

  to power your customer analytics apps.

  FnordMetric Frontend: FnordMetric Frontend is a ruby driven web interface for FnordMetric. It offers

  a ruby DSL and a collection of UI widgets to define custom dashboards. You can also write your own

  widgets or views on top of a ruby api.
