对CPU进行压力测试

stress.sh

#对CPU进行压力测试
cpu_number=$(grep -c 'processor' /proc/cpuinfo)
#模拟CPU在内核使用率达到100%的场景。
stress --cpu $cpu_number

输出结果导txt文件中（StressResult.sh）

#!/bin/bash
# 添加当前时间信息
echo "当前时间为$(date)" >> stress.txt
echo "模拟CPU在内核使用率达到100%的场景:" >> stress.txt

./stress.sh & # run stress.sh in the background
pid=$! # get the PID of the background process

SECONDS=0 # initialize SECONDS variable to 0

while [ $SECONDS -lt 50 ] # check if script has been running for less than 50 seconds
do
  echo "Current value of SECONDS: $SECONDS" >> stress.txt
  uptime >> stress.txt
  #echo "\n处理器实时统计信息如下" >> stress.txt
  #-P ALL参数指定该命令应报告所有处理器的统计信息
  #mpstat -P ALL 5 1 >> stress.txt
  #echo "\n" >> stress.txt
  SECONDS=$((SECONDS+2))
  sleep 2
done

kill -9 $pid # kill the background process after 50 seconds
kill $(pgrep stress)
kill $(pgrep StressResult.sh)
kill $(pgrep sleep)
