[tex=md]# DNS压力测试脚本说明（版本2）
##版本2中的新功能
* 提高了统计效率
* 更改逻辑结构，现在可以统计多种数据了
* 可以统计的数据有：发送总数、成功数、失败数和速率
* 删除脚本queryperf_parallel，并收录进脚本queryperf_parallels
* 更改了脚本的运行方式，使其更加统一
##简要说明
压力脚本的核心是并行运行多个queryperf进程，发出大量的DNS请求包，以查看其处理性能
文件清单
脚本名|功能|使用说明
-----|-----|-----
queryperf_polling|以轮询的方式运行|./queryperf_polling t n (t表示每轮运行时间，n表示queryperf轮询最大数量)
queryperf_parallels|可自定义并发数运行|./queryperf_parallels t n1 n2... (t表示每轮运行时间，n1、n2...表示queryperf轮询数量)
runallstress.sh|启动压力|被以上脚本所调用
stopallstress.sh|停止压力进程|同上（偶尔会出现类似提示`./kill.sh: line 9: kill: (31683) - No such process`不影响测试）
analysis_results.sh|分析日志|同上
extract_persec.sh|分析日志|同上
countsum.sh|分类求和|同上
statistics.sh| 统计求和信息|同上
test_dns.sh|指定目标测试机|更改脚本内的ip地址，来更改目标测试机
killallstress.sh|还原测试环境|./killallstress.sh 如果压力测试被中断，请运行该脚本
*.com.test|域名文件|测试所用到域名，都放在这里
##queryperf_polling
该脚本可以逐步增加queryperf的并行数量，通过比较运行结果来探寻最合适的压力数量
> 比方说运行./queryperf_polling 100 3
> 代表一共运行3轮，每轮运行100秒
第一轮运行1个queryperf，运行100秒后统计分析数据，并将统计结果打印在屏幕上
第二轮运行2个queryperf，运行100秒后统计分析数据，并将统计结果打印在屏幕上
第三轮运行3个queryperf，运行100秒后统计分析数据，并将统计结果打印在屏幕上
运行结束后会将总统计结果打印在屏幕上
逻辑图：
##queryperf_parallels
可以单独定义每轮测试所使用的queryperf并发数
> 比如运行./queryperf_parallels 100 3 4
> 代表一共运行2轮，每轮运行100秒
第一轮运行3个queryperf，运行100秒后统计分析数据，并将统计结果打印在屏幕上
第二轮运行4个queryperf，运行100秒后统计分析数据，并将统计结果打印在屏幕上
运行结束后会将总统计结果打印在屏幕上
逻辑图：
##运行样例
> 注：实际测试时，不会只用10秒
