性能工具之 JMeter 使用 shell 脚本快速执行

一、背景

在 Linux 中执行 JMeter 脚本时候，大家是否一直使用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 脚本或者 python 快速执行.

今天简单介绍下 shell 脚本执行。前置条件需要配置 JMeter 环境变量，如果没有配置，需要在脚本中修改相应位置。

二、效果

shell 脚本：

三、环境变量配置

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

#执行生效：
source ~/.bash_profile

验证：

四、脚本解析

1、参考代码

#!/bin/bash
# author:7DGroup
# 2019/12/08/20/50

cmdsh="/home/gaolou/apache-jmeter-3.1/bin/JMeterPluginsCMD.sh"
case=$1
mNum=$2
durationTime=$3
mark=$4
resultDataFileName="resultData.csv"
#hostIps="101.201.210.163"
nowPwd=`pwd`

echo -e "\033[32m-压力机开始执行。。请等待-\033[1m"

echo testcaseName:${case}_${mNum}_${durationTime}_${mark}
if [ -z ${case} ];then
        echo -e "\033[32m请输入脚本名，线程数，执行时间，备注! 输入脚本名\033[0m"
        echo "ERROR"
        exit 1
fi
if [ -z ${mNum} ];then
        echo -e "\033[32m请输入脚本名，线程数，执行时间，备注! 输入线程数\033[1m"
        echo "ERROR"
        exit 1
fi
if [ -z ${durationTime} ];then
        echo -e "\033[32m请输入脚本名，线程数，执行时间，备注! 输入备注\033[1m"
        echo "ERROR"
        exit 1
fi

oneTest(){
   
   
    filename=${case}_${mNum}_${durationTime}_${mark}
    echo "filename:"${filename}
    mkdir -p ${nowPwd}/${case}
    cd ${nowPwd}/${case}
    cp ${nowPwd}/testPlan/${case}.jmx ${nowPwd}/${case}/${case}.jmx
    if [ ! -f ${resultDataFileName} ];then
                echo -e "sceneName,sceneThreadNum,duration(s),interfaceName,interfaceNum,totalCount,tps,errorPersent,avgTims(ms),persentTime(ms)" > ${resultDataFileName}
    fi
    rm -rf ${filename}
    mkdir ${filename}
    cp ${case}.jmx ${nowPwd}/${case}/${filename}/${filename}.jmx
    cd ${nowPwd}/${case}/${filename}/
    sed -i "s#name=\"ThreadGroup\.num_threads\">2<#name=\"ThreadGroup\.num_threads\">$((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

   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

    ${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
}
oneTest

echo -e "\033[32m-压力已经结束-\033[1m"

2、主要逻辑

脚本执行方法：

• 给予可执行权限：chomd a+x startJmeter.sh
• 执行方法：sh startJmeter.sh 脚本名字 并发数 执行时间 备注

cmdsh="/home/gaolou/apache-jmeter-3.1/bin/JMeterPluginsCMD.sh"
case=$1  #脚本名字
mNum=$2  #并发数 
durationTime=$3  #执行时间
mark=$4    #备注
resultDataFileName="resultData.csv"  #csv命令保存数据
#hostIps="101.201.210.163"   #如果是多台机器需要取消该注释，把压力机器全部加上

通过 sed -i 替换执行并发数、执行时间等信息

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

通过封装 Jmeter -n -t 。。。等信息去执行脚本，该执行命令可以根据自己需要修改

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

结果保存通过插件 JMeterPluginsCMD.sh 执行获取 csv 数据，如果想知道该插件详细信息可以搜索下怎么使用。

${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

JMX 脚本写法需要注意

这里实际上 shell 脚本是替换【ThreadGroup.num_threads">1】

3、目录说明

脚本存放目录：

shell 脚本存放位置：

执行结果：

1. 表示当前执行的脚本名字
2. 表示原始脚本
3. csc 结果保存

执行脚本结果目录说明：

打开脚本：

vim日志：

4、下载报告

使用 tar 命令

• 解包：tar zxvf FileName.tar
• 打包：tar zcvf FileName.tar DirName

下载：

sz filename.tar

下载解压后打开：

五、总结

通过 shell 脚本执行Jmeter脚本，如果是长时间执行可以采用后台执行方法，加上 nohup 这样执行不用担心 ssh 窗口执行失败。
