关于jmeter:性能工具之Jmeter使用shell启动

jiezi

背景

在 linux 中执行 Jmeter 脚本时候，大家是否始终应用【jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]】命令执行，是否想过通过 shell 命令执行或者 python 执行，明天简略介绍下 shell 命令执行, 前置条件须要配置 Jmeter 环境变量，如果没有配置，须要在脚本中批改相应地位。

成果

shell 脚本

Jmeter 环境变量配置参考

vi ~/.bash_profile#jmeter: 门路 JMETER_HOME=/root/tools/apache-jmeter-3.3PATH=$PATH:$HOME/bin:$JMETER_HOME/bin:export PATH

执行失效：source ~/.bash_profile

验证

shell 脚本参考代码

!/bin/bash

解释：
第一步

脚本执行办法：

先给予可执行权限：chomd a+x startJmeter.sh

执行办法：sh startJmeter.sh 脚本名字 并发数  执行工夫  备注

解释：

cmdsh=”/home/gaolou/apache-jmeter-3.1/bin/JMeterPluginsCMD.sh”

case=$1 #脚本名字

mNum=$2 #并发数

durationTime=$3 #执行工夫

mark=$4 #备注

resultDataFileName=”resultData.csv”  #csv 命令保留数据

hostIps=”101.201.210.163″ 

  #如果是多台机器须要勾销该正文，把压力机器全副加上

要害中央解释：

阐明：通过 sed -i 替换执行并发数、执行工夫等信息

sed -i “s#name=\”ThreadGroup.num_threads\”>2<#name=\”ThreadGroup.num_threads\”>$((2*mNum))<#g” ${filename}.jmx

sed -i “s#name=\”ThreadGroup.num_threads\”>1<#name=\”ThreadGroup.num_threads\”>$((1*mNum))<#g” ${filename}.jmx

sed -i “s#ERRORXML#${nowPwd}/${case}/${filename}/${filename}_ERROR.xml#g” ${filename}.jmx

sed -i “s#ThreadGroup.scheduler\”>.*</#ThreadGroup.scheduler\”>true</#g” ${filename}.jmx

sed -i “s#LoopController.loops\”>.*</#LoopController.loops\”>-1</#g” ${filename}.jmx

sed -i “s#LoopController.continue_forever\”>.*</#LoopController.continue_forever\”>true</#g” ${filename}.jmx

sed -i “s#ThreadGroup.duration\”>.*</#ThreadGroup.duration\”>${durationTime}</#g” ${filename}.jmx

命令执行解释：

阐明：通过封装 Jmeter -n -t。。。等信息去执行脚本，该执行命令能够依据本人须要批改

if [-z ${hostIps} ];then

jmeter -n -t ${filename}.jmx -l ${filename}.jtl -j ${filename}.log

jmeter -n -t ${filename}.jmx -l ${filename}.jtl -j ${filename}.log -e -o ${filename}

else

jmeter -n -t ${filename}.jmx -R ${hostIps} -l ${filename}.jtl -j ${filename}.log -e -o ${filename}

jmeter -n -t ${filename}.jmx -R ${hostIps} -l ${filename}.jtl -j ${filename}.log

fi

后果保留解释：

阐明：通过插件 JMeterPluginsCMD.sh 执行获取 csv 数据，如果想晓得该插件详细信息能够百度查问怎么应用。

${cmdsh} –generate-csv ${filename}.csv –input-jtl ${filename}.jtl –plugin-type AggregateReport

local sumThread=grep "<stringProp name=\"ThreadGroup.num_threads\">" ${filename}.jmx |awk -F\> '{print $2}'|awk -F\< 'BEGIN{sum=0}{sum=sum+$1}END{print sum}'

if [-z ${hostIps} ];then

hostNum=1

else

hostNum=echo ${hostIps}|awk -F, '{print NF}'

let sumThread=sumThread*hostNum

let mNum=mNum*hostNum

fi

sed -n ‘2,$p’ ${filename}.csv|grep -v TOTAL| awk -F, -v case=${filename} -v tnum=${sumThread} -v duration=${durationTime}

‘{printf(“%s,%s,%s,%s,%s,%s,%s,%s,90%time:%s;95%time:%s;99%time:%s\n”,case,tnum,duration,

$1,$2,$11,$10,$3,$5,$6,$7)}’ >> sDGroup

local totalGroup=cat sDGroup|wc -l

for((i=1;i<=${totalGroup};i++))

do

sed -n “${i}p” sDGroup|awk -F, -v tnum=${mNum} ‘{printf(“%s,%s,%s,%s,%s,%s,%s,%s,%s,%s\n”,$1,$2,$3,$4,tnum,$5,$6,$7,$8,$9)}’ >>../${resultDataFileName}

done

第二步
脚本写法须要留神

下面脚本写法须要多多留神，否则在通过脚本执行会达不到本人成果；

脚本替换 xml 阐明

实际上 shell 脚本是替换【ThreadGroup.num_threads”>1</stringProp>】

脚本寄存目录

第三步
shell 脚本寄存地位

第四步
执行后果

示意以后执行的脚本名字

示意原始脚本

csc 后果保留

执行脚本后果目录阐明

阐明：

关上脚本

vim 日志

通过查看日志能够看出执行全副信息，这样不便脚本调试脚本与谬误跟踪

下载报告

tar 命令

解包：tar zxvf FileName.tar

打包：tar zcvf FileName.tar DirName

sz filename.tar

下载解压后关上

tps

总结

     通过 shell 脚本顺利执行 Jmeter 脚本，如果是长时间执行能够采纳后盾执行办法，加上【nohup sh startJm.sh 脚本 并发数据 执行工夫 备注 &】这样执行不必放心 ssh 窗口执行 Jmeter 失败，通过 tail -f nohup.log 查看执行日志。
