收集Linux系統資源，導入到LoadRunner測試結果

LoadRunner的結果分析器自帶數據導入功能，以下腳本即可辦到：
    收集數據 == $ performanceMonitor.sh run    保存到CSV文件 == $ performanceMonitor.sh csv YYYYMMDD
腳本代碼：
LOG=/home/higkoo/PerfMon/
SLEEP=10
HDD=2

HTYPE=$(uname -s)

genStat()
{
    now=$( date +%S )
    while [ "$now" -ne "30" ]
    do
        sleep 1
        now=$( date +%S )
    done
    while :;
    do
        dat=$(date +%Y%m%d,%H:%M:%S)
        day=$(date +%Y%m%d )
        iostat -x 1 2 | sed -e"s/^\(.*\)/$dat \1/" | grep "[0-9]\." | tail -${HDD} >> ${LOG}/io.${day}.log &
        vmstat 1 2 | awk "{ print \"$dat\", \$0 }" | tail -1 >> ${LOG}/vm.${day}.log &
        netstat -i | grep -v Iface | awk "{ print \"$dat\", \$0 }" >> ${LOG}/netstat.${day}.log &
        uptime >> ${LOG}/uptime.${day}.log &

esac腳本可能需要根據實際情況稍作修改，然后將保存的數據導入到LoadRunner里就可以合成到測試結果中了：
