运维进行时

      为了更好管理、维护LVS平台，本人基于Django+certmaster+func开发了一套管理平台，主要功能模块分为性能图表、数据中心、虚拟IP池、主机管理、监控模块等功能，基本上是按F5－LTM管理平台思路来设计，下面只要对这几大块功能进行说明。
1、性能图表
功能说明：以小时、日、星期、月、年的图表展示LVS SERVER、VIP、SERVER等流量情况，效果图如下：

A brand new Rails/Merb app you put together over a weekend, a pack of Mongrels, a reverse proxy (like Nginx), and you're up and running. Well, almost, what about that one request that tends to run forever, often forcing the user to double check their internet connection? Response time is king, and you always want to make sure that your site feel snappy to the user. Did you know that Flickr optimizes all of their pages to render in sub 250ms?
When you're fighting with response times, the worst thing you can possibly do is queue up another request behind an already long running process. Not only does the first request take forever, but everyone else must wait in line for it to finish as well! To mitigate the problem HAProxy goes beyond a simple round-robin scheduler, and implements a very handy feature: intelligent request queuing!
