FnordMetric is a highly configurable (and pretty fast) realtime app/event tracking thing based on ruby eventmachine and redis. You define your own plotting and counting functions as ruby blocks! See it in action! (RailsCasts)
Documentation: fnordmetric.io
FnordMetric is based on ruby eventmachine and needs to run in a seperate ruby process. The preferred way to start it is to create a ruby file (where you put your DSL statements) and execute it (more about that in the documentation)
Save this to my_fnordmetric.rb
require "fnordmetric"
FnordMetric.namespace :myapp do
# render a timeseries graph
widget 'Sales',
:title => "Sales per Minute",
:gauges => [:sales_per_minute],
:type => :timeline,
:width => 100,
:autoupdate => 1
end
FnordMetric.standaloneIn this case we created one timeseries chart on the dashboard "Sales" that will display the number of sales_per_minute and auto-refresh every second.
You should now be able to start the dashboard on http://localhost:4242/ (default) by running:
$ ruby my_fnordmetric.rb
Now we can start sending data to FnordMetric. The canonical way to submit data is the HTTP API. This will report a single sale:
curl -X POST -d '{ "_type": "_incr", "value": 1, "gauge": "sales_per_minute" }' http://localhost:4242/events
There are various other ways to submit events to FnordMetric (more information in the documentation).
FnordMetric offers a HTML5 / JavaScript API (called FnordMetric UI) that allows you to plug real-time data and charts into any website without having to write code. This is achieved by including a JavaScript library and using data-* attributes on html elements to declare the widgets.

<script src='http://localhost:4242/fnordmetric-ui.js' type='text/javascript'></script>
<span
data-fnordmetric="counter"
data-gauge="sales_per_minute"
data-autoupdate="1"
data-unit="€"
>0</span>
<script>
FnordMetric.setup({
"address": "localhost:4242",
"namespace": "myapp"
});
</script>gem install fnordmetric
or in your Gemfile:
gem 'fnordmetric', '>= 1.0.0'
