篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了性能工具之Jmeter使用shell启动相关的知识,希望对你有一定的参考价值。
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命令执行或者python执行,今天简单介绍下shell命令执行,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。
效果
shell脚本
Jmeter环境变量配置参考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
#!/bin/bash
# author:liwen
# 7DGroup
# 2019/12/08/20/50

第一步
脚本执行方法:
-
先给予可执行权限: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
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=$4 #备注
resultDataFileName="resultData.csv" #csv命令保存数据
#hostIps="101.201.210.163"
#如果是多台机器需要取消该注释,把压力机器全部加上
关键地方解释:
说明:通过sed -i 替换执行并发数、执行时间等信息
sed -i "s#name=\\"ThreadGroup\\.num_threads\\">2<#name=\\"ThreadGroup\\.num_threads\\">$((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
命令执行解释:
说明: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
结果保存解释:
说明: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百度查询怎么使用。
${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
第二步
脚本写法需要注意
上面脚本写法需要多多注意,否则在通过脚本执行会达不到自己效果;
脚本替换xml说明
实际上shell脚本是替换【ThreadGroup.num_threads">1</stringProp>】
脚本存放目录
第三步
shell脚本存放位置
第四步
执行结果
-
表示当前执行的脚本名字
-
表示原始脚本
-
csc结果保存
执行脚本结果目录说明
说明:
打开脚本
vim日志
通过查看日志可以看出执行全部信息,这样方便脚本调试脚本与错误跟踪
下载报告
tar命令
解包:tar zxvf FileName.tar
打包:tar zcvf FileName.tar DirName
sz filename.tar
下载解压后打开
tps
总结
通过shell脚本顺利执行Jmeter脚本,如果是长时间执行可以采用后台执行方法,加上【nohup sh startJm.sh 脚本 并发数据 执行时间 备注 &】这样执行不用担心ssh窗口执行Jmeter失败,通过tail -f nohup.log查看执行日志。
