Showing stats with collectd + d3js

Collectd3 is a modern visualization of collectd system performance statistics. It does more than just visualizes the data. It generates a bird-eye view of multy-server system and enables to quickly spot the problems and dig down for details.

It integrates with other graphical tools,like Collectd Graph Panel

See the live demo.

Pre-requisites:

nodejs 0.8 or later
npm 1.2.x
rrdtool - http://oss.oetiker.ch/rrdtool
librrd-dev - required for node_rrd, to build node bindings (on Ubuntu, apt-get install librrd-dev)
access to your collectd data

Install dependencies

Install rrdtool. On Mac, homebrew works fine. On Linux - install rrdtool and librrd-dev. E.g., apt-get install rrdtool, apt-get install librrd-dev. On Windows, figure this out yourself (and add instructions here). Make sure rrdtool is on the path and working (try $ which rrdtool, $ rrdtool).
Get node dependencies:
```
 $ npm install
```

Unit tests

Run node unit tests:

by npm (a script is configured in package.json)
```
  $ npm test
```

or manually

  env NODE_ENV=test node_modules/.bin/mocha -R spec

Browser unit tests - not implemented yet.

Configure

Open config/default.yml. Modify data-directory to point out to collectd files. Change the port of web app. Define and adjust host categoreis (use regular expressions). Adjust storage partitions, disks, etc. See comments in default.yml

Configs are read and extend each other sequentially in a specific order: default.yml, NODE_ENV.yml (like test.yml for NODE_ENV=test), HOSTNAME.yml (like collectd.yml for collectd.example.com).

If you want specific section to be handled as-is and prevent it from being overriden or extended by any other config file loaded later, you should add ~override: true to it.

For more info, see comments in default.yml and YAML documentation

Sample data

When developing, testing, or trying this out, work with sample data.

Download the sampledata(https://s3-us-west-1.amazonaws.com/stackstorm/collectd3-sampledata/sampledata.zip), unzip and place under collectd3 (or place anywhere and adjust the data-ditectory in config)
In config, uncomment last-timestamp: 1370643660 in the server section

Run server

	$ npm start

This launches the server on the background; the output is redirected to server.out.log and server.err.log. To check server status, use forever - e.g., node_modules/forever/bin/forever list. To stop the server:

	$ npm stop

Developing

Always use grunt. It will watch for changes and recompile, lint and unit-test each file you change. If you use npm start, you need to do it manually (except for less files, they would be recompiled before each start).

Run grunt:

by first installing grunt-cli globally (npm install grunt-cli -g)
```
  $ grunt
```
by using grunt-cli which already installed locally
```
  $ node_modules/.bin/grunt
```
