CPU降频监测

检查和记录CPU频率脚本，用于辅助监测CPU降频问题

mkdir allfreInfo
touch avefreInfo.log
num=`cat /proc/cpuinfo | grep -i mhz | awk '{print $4}' | wc -l`
times=1
while true;do
    
    total=0
    date=`date +%Y-%m-%d-%H:%M:%S`
    touch allfreInfo/$date-allfreInfo.log
    echo "$date" >> allfreInfo/$date-allfreInfo.log
    turbostat -q -n 1 -i 1 -o allfreInfo/$date-allfreInfo.log
    for i in `cat /proc/cpuinfo | grep -i mhz | awk '{print $4}'`;do
        total=`echo "scale=1;$total + $i" | bc`
    done
    average=`echo "scale=1;$total / $num" | bc`
    echo "$date : $average" >> avefreInfo.log
    sleep 300s
    echo "the $times times check finished...."
    let times+=1
