Spine―Cacti高效轮训器
Spine―Cacti高效轮训器
简介
Cacti是流行的流量监控软件。spine是一个基于C语言的，Spine非常精简，只用了大概500行CoffeeScript代码。轻量级和简介是Spine的基础。非常快速的轮询引擎。它是默认的cmd.php的可选替代，主要是为了加快SNMP轮询。如果你发现你的cmd.php 运行超过300 秒的话，推荐使用Spine。
异步结构――太多太多JavaScript应用和框架没能充分利用客户端渲染的作用。最终用户不关心后台请求服务器是否还在等待，更不想去看“正在加载”的消息和提示。用户渴望流畅的界面，流畅的互动。为了实现这个，Spine在浏览器端存储和渲染所有事物，并异步和服务器通信。
Spine本身相当简单的，她的库很小，API很极小
