Grafana Dash Gen Build Status

A collection of utility classes to construct and publish grafana graphs. The library is built ground up to incorporate grafana terminologies.

  • Dashboard: Represents the final dashboard that is displayed.
  • Row: A row in grafana. Dashboard consists or many rows.
  • Panel: A visual display item. A panel could be a graph, single stat or others. A row consists of many panels.
  • Target: A dot separated graphite string. E.g, a.b.count. A Panel consists of many targets.
  • Annotations: Lined markers that will annotate a graph (panel). A Dashboard can have annotations added to it.
  • Templates: Variables that can be included in the state. E.g, a.$dc.b.count (to switch between datacenters). A Dashboard can have templates added to it.

Code to generate the dashboard

You will be able to generate and publish a grafana graph using the following steps.

Step 1: Configure grafana

if you would like grafana to publish your dashboard you need this step. If you do not need grafana to publish your dashboard, you can skip this step.

var grafana = require('grafana-dash-gen');
var Row = grafana.Row;
var Dashboard = grafana.Dashboard;
var Panels = grafana.Panels;
var Target = grafana.Target;
var Templates = grafana.Templates;

grafana.configure({
	url: 'https://your.grafana.com/elasticsearch/grafana-dash/dashboard/',
	cookie: 'auth-openid=someidhere'
});

Step 2: Create a dashboard

var dashboard = new Dashboard({
	title: 'Api dashboard'
});

(or) Below is an example of a dashboard with a custom slug, templates dc and smoothing and annotations.

 var dashboard = new Dashboard({
 	title: 'Api dashboard',
 	slug: 'api',
 	templating: [{
 		name: 'dc',
 		options: ['dc1', 'dc2']
 	}, {
 		name: 'smoothing',
 		options: ['30min', '10min', '5min', '2min', '1min']
 	}],
 	annotations: [{
 		name: 'Deploy',
 		target: 'stats.$dc.production.deploy'
 	}]
 });

If you do not wish to have any templates and annotations

Step 3: Create a new row

As said abolve, grafana dashboard contains a number of rows.

var row = new Row();

Step 4: Create graphs to add to the row

There are two ways to add the graph to a row. Pass it while a graph is created as below

var panel = new Panels.Graph({
	title: 'api req/sec',
	span: 5, 
	targets: [
		new Target('api.statusCode.*').
					transformNull(0).sum().hitcount('1seconds').scale(0.1).alias('rps')
	],
	row: row,
	dashboard: dashboard
});

(or) add it in a separate step

var panel = new Panels.Graph({
	title: 'api req/sec',
	span: 5,
	targets: [
		new Target('api.statusCode.*').
					transformNull(0).sum().hitcount('1seconds').scale(0.1).alias('rps')
	]
});
row.addPanel(panel);

If you would like to create a full width single stat (as in the image) the code is below. Notice how we create a new row on the fly.

var requestVolume = new Panels.SingleStat({
	title: 'Current Request Volume',
	postfix: 'req/sec',
	targets: [
		new Target('stats.$dc.counts').
				sum().scale(0.1)
	],
	row: new Row(),
	dashboard: dashboard
});

Step 5: Publish the graph

grafana.publish(dashboard);

to generate the json and not publish use

console.log(dashboard.generate());

A complete example of a dashboard is provided in example.js
