开发分布式网络监控分析之前端ajax展现那些事

2020-05-26 Ajax 前端之家

前端之家收集整理的这篇文章主要介绍了开发分布式网络监控分析之前端ajax展现那些事，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

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://www.jb51.cc/article/p-vncyxpyj-ng.html

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。

// if network.http.keep-alive is true,and if NOT connecting via a proxy,then
pref("network.http.m camerabagss.us a x-persistent-connections-per-server",6);
// if network.http.keep- camerabagss.us a live is true,camerabagss.us a nd if connecting vi camerabagss.us a   camerabagss.us a  proxy,then  camerabagss.us a
// new connection will only be  camerabagss.us a ttempted if the number of  camerabagss.us a ctive persistent
// connections to the proxy is less then m camerabagss.us a x-persistent-connections-per-proxy.
pref("network.http.max-persistent-connections-per-proxy",8);

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。

<script type="text/javascript">
$(document).ready(function(){
          $("[ id = nima ]").click(function(){
                $("[ id =kk] li").each(function(){
 //                   alertify.log($(this).text())
                         zhi=$(this).text();
                         $.ajax({
                             type: "POST",url: "/queue",data : {'key':zhi},async:true,error: function(){
                                     alert('nima');
                             },success: function(data,status){
                                     alertify.log(data);
                             }
                         });
                                                                                                                                                                                                                                                                                                                                                                                                             
                });
           });
  });
</script>

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。
