How-to set up and use graphite on Ubuntu

Graphite 是一个Python写的web应用,采用django框架,Graphite用来进行收集服务器所有的即时状态,用户请求信息,Memcached命中率,RabbitMQ消息服务器的状态,Unix操作系统的负载状态,Graphite服务器大约每分钟需要有4800次更新操作,Graphite采用简单的文本协议和绘图功能可以方便地使用在任何操作系统上。 Graphite 仅是一个画图工具,不主动地收集数据,而是将接收到的数据以图形的方式展现出来。 因为Graphite不收集数据,所以需要将指定格式的数据发送给Graphite,其在将受到的数据,绘制成图像。 Graphite的功能

  • 存储时间序列数据
  • 根据需要呈现数据的图形

Graphite 三大组件:

  1. Graphite-Web, a Django-based web application that renders graphs and dashboards
  2. The Carbon metric processing daemons
  3. The Whisper time-series database library

Graphite Overview

What Graphite is and is not

Graphite does two things:
  1. Store numeric time-series data
  2. Render graphs of this data on demand
What Graphite does not do is collect data for you, however there are some tools out there that know how to send data to graphite. Even though it often requires a little code, sending data to Graphite is very simple.

About the project

Graphite is an enterprise-scale monitoring tool that runs well on cheap hardware. It was originally designed and written by Chris Davis at Orbitz in 2006 as side project that ultimately grew to be a foundational monitoring tool. In 2008, Orbitz allowed Graphite to be released under the open source Apache 2.0 license. Since then Chris has continued to work on Graphite and has deployed it at other companies including Sears, where it serves as a pillar of the e-commerce monitoring system. Today many large companies use it.

The architecture in a nutshell

Graphite consists of 3 software components:
  1. carbon - a Twisted daemon that listens for time-series data
  2. whisper - a simple database library for storing time-series data (similar in design to RRD)
  3. graphite webapp - A Django webapp that renders graphs on-demand using Cairo
Feeding in your data is pretty easy, typically most of the effort is in collecting the data to begin with. As you send datapoints to Carbon, they become immediately available for graphing in the webapp. The webapp offers several ways to create and display graphs including a simple URL API for rendering that makes it easy to embed graphs in other webpages.
