前言：

在软件开发中，压测和测试是非常重要的一个环节，它可以帮助我们更加全面地检测软件中的安全漏洞和风险。paramiko 是 Python 中的一个模块，可以帮助我们通过 SSH 协议进行远程登录和操作。JavaScript 是一种常用的脚本语言，可以帮助我们更加方便地进行网页测试和监控。

python tornado 异步框架压测

import tornado.ioloop
from tornado.httpclient import AsyncHTTPClient
def handle_request(response):
  if response.error:
      print ("Error:", response.error)
  else:
      print(response.body)
param = {"msg":"111"}
param["img_msg"] = open("t.jpg",'r',encoding='utf-8')
url = 'http://gc.ditu.aliyun.com/geocoding?a=苏州市'
i = 1
print(param)
req = tornado.httpclient.HTTPRequest(url, 'POST', body=str(param))
http_client = AsyncHTTPClient()
while i<10000:
  i += 1
  http_client.fetch(req, handle_request)
tornado.ioloop.IOLoop.instance().start()

python 协程压测端

#-*- coding: utf-8 -*-
import urllib.request
# url = "http://r.qzone.qq.com/cgi-bin/user/cgi_personal_card?uin=284772894"
url = "http://gc.ditu.aliyun.com/geocoding?a="+urllib.request.quote("苏州市")

        self.func = func
    def _run(self):
        # gevent.sleep(self.n)
        self.func


count = 3
green_let = []
for i in range(0, count):
    green_let.append(MyGreenlet(f(url)))
for j in range(0, count):
    green_let[j].start()
for k in range(0, count):
    green_let[k].join()

• 当然也可以用多线程，apache ab 等，如果是大量并发可以使用 netty nio 压测 + 虚拟机的方式（其实原理差不多，协程，tornado 等）

远程监控

• 把此 shell 脚本上传到服务器

  #!/bin/bash
  if (( $# != 1))
  then
  echo "please input sum times:"
  exit 1
  fi
  sar -u 1 $1 | sed '1,3d'|sed '$d' > sar_cpu_1.txt
  sar -r 1 $1 |sed '1,3d'|sed '$d' > sar_men_1.txt
  sar -b 1 $1 |sed '1,3d'|sed '$d' > sar_io_1.txt
  

• 远程上传 shell 脚本，执行，下载日志

import paramiko

server_user = 'root'
server_passwd = ''
server_port = 22

js 解析日志

• js 分析日志文件.cpu,内存,io 都是基于这样分析 用的 highcharts 插件，自己去学习吧

<script>
    var idle= [];
    var iowait = [];
    var categories = [];
    var temp;
    $(function () {
        $.get( "txt/sar_cpu.txt", function( data ) {
            var resourceContent = data.toString(); // can be a global variable too...
            var rc = resourceContent.split("\n");
            for(var i=0; i<rc.length; i++){
             temp = getNotNullArr(rc[i].split(" "));
                console.log(temp);
                idle.push(parseFloat(temp[temp.length-1]));
                categories.push(temp[0]);
                iowait.push(parseFloat(temp[6]));
            }
            set_h_title("cpu使用情况");
            set_h_sub_title("test.com");
            set_h_xaxis_setp(1);
            set_h_tooltip("%");
            set_h_yaxis_title("cpu使用情况");
            set_h_xaxis_categories(categories);
            set_h_series( [{name: 'idle',data:idle}, {name: 'iowait', data: iowait}]);
            highchartsinit("#container",get_h_title(),get_h_sub_title(),get_h_xaxis_setp(),get_h_xaxis_categories(),get_h_yaxis_title(),get_h_tooltip(),get_h_series());
    });
    });
</script>
