<p>Graphite是一个database + 图形展示工具，我们可以将服务的各种指标数据发送给Graphite，Graphite的Web页面中会以曲线的形式展现这些数据，方便我们观察对比服务的运行状况。</p>
<p>下面是Graphite的架构图：</p>

<p>grahpite中所有的曲线数据都是可以使用函数进行操作的</p>
<img alt="_images/graphite-composer-1.png" src="_images/graphite-composer-1.png" />
<p>你也可以对这些生成的函数进行手工编辑：</p>

<p>效果图：</p>
<img alt="_images/dashboard.png" src="_images/dashboard.png" />
<p>点击graphite页面页面右上角的Dashboard链接，进入Dashboard页面，你可以直接在上面的面板中选择需要的曲线加入到dashboard中，所有的曲线都可以拖曳编辑。</p>
<p>当然你也可以直接打开dashboard的edit页面，按照下面两图手工编辑曲线的生成参数（生成复杂曲线的时候很有用）。</p>

<p>这个json数组里的每一个元素定义了一张图，target定义了在图上要显示哪几条曲线，title是图的标题。</p>
<p>target可以是单个曲线，也可以是多个曲线使用function进行的变换后的曲线。比如上面的例子中，第二张图就展示了yq30和yq34两台机器上的http 5xx出现比例的曲线（5xx出现的次数除上总请求数）。</p>
