周六自己在家甚是无聊，看到朋友们在讨论分布式监控分析，要的效果是 阿里测,17ce那种形式的，想查询监控啥的时候，在一个页面上能看到所以监控点提供的数据。比如，我想要查询针对一个url的get，dig数据。在这边直接采用zabbix、nagios的数据不太合理，因为我想要是给客服和客户用的界面。 像zabbix这样，咱们只能是提前先配置好。
以前做过类似的全网监控检测，但是做的有些简陋，但也和这次聊的话题不一样，有兴趣的朋友可以看看以前的我写的关于大屏幕开发的文章。 http://rfyiamcool.blog.51cto.com/1030776/1302398
本来以为不算难的东西，只要我从前端把你要查询的节点数据给后端，然后用table展现不就行了。 自己写demo的时候，遇见了不少的问题。
真正做的时候，我发现浏览器是有线程并发限制的，firefox是6个，chrome也是6个，ie 6/7 是2个吧 。ie8 才是6个。
firefox的修改线程的方式，这里是告诉大家，这东西是可以改的。 但是对于客户来说，你不能老让他改呀。

一开始我的做法是、从这个页面确定用户要查询的监控节点。然后each遍历数据，ajax 异步执行。但这个时候，我前面说的线程数超过6个后，后面的任务会堵塞，这个堵塞会总是浏览器的崩溃。
不能让用户改线程数，不改的话，浏览器会卡掉的。不知道用websocket的方式，能不能突破浏览器的限制，以前做websockek都是分段提供的数据，一下子超过6条的堵塞数据，还真没有尝试过。
这个是刚才写的例子，li模拟了100个，结果很很卡。数据的返回是每次6个 。

这个时候看了下别人的做过，他们都是把压力放到了后端。也就是说，我从前边发出了一个请求后，我会每隔一段时间去访问后端的接口，然后把数据渲染后页面上，这里会做相应的判断，已经展现的数据，我就不重复展现了，还没有展现的我继续渲染页面。
这个是后端接口返回的json数据。

总觉得用saltstack也是可以试试的，有时间的朋友可以做些测试。 不用太复杂，用他的模块，提供url的参数就可以了。
