minum-dashboard v0.2.4

metrics-io-dashboard

Dashboard for visualize and correlate metrics tracked via minum

Design Decisions

• Cloud Ready - Easily deployable into cloud
• Portable - Run as a standalone app locally
• Embeddable - Easily embed into existing nodejs webapp

Dependencies

• Mongodb (2.1+)
• NodeJs

Accessing Dashboard

There are few ways you can access the dashboard.

1. Standalone App

Install minum-dashboard binary via npm

npm install minum-dashboard -g

Start Dashboard

minum-dashboard -m <mongodb url>

2. Deploy into Cloud

You can deploy dashboard into popular cloud providers in few minutes. First download or clone this repository into your local machine.

Heroku

• You can deploy dashboard into heroku as you do with other apps
• But first edit conf/config.json for basic-auth settings and mongo-url
• If you are thinking to use mongodb addon on heroku, add it first and get the mongo-url and configure it with conf/config.json

3. Deploy as a nodejs app manually

• This repository is a deployable nodejs app and can be deployed as a typical nodejs app.
• By default dashboard runs with basic-auth and can be configured at /conf/config.json
• But it is recommend to run dashboard behind nginx with ssl and basic_auth.
• You can configure port and mongo-url in /conf/config.json
• After that run start-dashboard.js with nodejs

  	node start-dashboard.js

4. Embed with an existing express webapp

var express     = require('express');
var dashboard   = require('minum-dashboard');
var webapp      = express();

var MONGO_URL = "mongodb://localhost/test";
dashboard.listen(MONGO_URL, webapp, { prefix: '/metrics'});

webapp.listen(5005);

Using Dashboard

Inside the Dashboard you can create as many graphs as you need. You can correlate metrics too. (use area chart type)

There is no UI for defining graphs. But we have simple and flexible syntax to define them.

We simply did no use JSON since, it is too heavy for taking user inputs

Syntax

Here is how you define a graph.

<title for graph> | <graph-type> | <metric-name> | <value-aggregator>, <source-aggregator> | <resolution> | <time-length>

eg:- CPU Usage | area | cpu | avg, sum | five_secs | 1000 * 60 * 15

• Supported values for graph-type : area, line
• Supported values for value-aggregator : sum, avg, min, max
• Supported values for source-aggregator : sum, avg, min, max
• Supported values for resolution : five_secs, minute, hour, day
• You can use multiple lines to specify multiple graphs
• Empty lines add empty block to dashboard instead of the graph

Permalink URLs

• Configuration you do will be saved in the URL.
• So you can simply copy URL and share with others.
• You can http://bit.ly or http://goo.gl to shorten the URL
