前言
这个工具最开始是从sebastien的blog里面看到的,这个是 Gregory Charot(工具的作者)写的,通常我们在获取一个ceph的信息的时候,需要敲一连串的命令去获得自己需要的信息,可能需要一大堆的解析才能完成,而经常出现的是,使用了后,下次使用的时候,又要重来一遍,所以作者把这些常用的操作做了一些归纳,形成了一个查询的工具,很多人有个相同的观点就是,越懒,就会想办法提高效率,当然,首先得有提高效率的意识,否则只剩下懒了
我做的事情就是把作者用shell的逻辑转换成了python的版本,这样也方便自己以后的扩展,这里感谢作者做的一些工作,让我很快就能完成了,这里并不是重复造车轮,本来自己就不会python,权当练手了
在linux下面我是不建议用中文的,但是这个工具里面还是改成用中文提示,因为中文可能看上去更清楚需要做的是一个什么事情,这个仅仅是一个查询工具
有一段时间没有更新blog了,主要是最近比较忙,没有时间去看太多的资料,没有时间来写下更多的东西,有时间还是会坚持写下去

总结
本篇只是暂时结束了,目前完成了原作者的一些想法,等有空再写点自己比较注重的数据
最近一直在关注冯大辉的事情,看完后还是原来的感觉,在利益面前,公司总是会追求最大化,当出现分离的时候,总会显得无情,还是自己让自己强大一点,拿到属于自己的那一部分就好
