1 啟動操作記錄命令，記錄下所有操作及輸出結果
#script /perf-mon-config.log
2 創建性能監測腳本文件/perfmon.sh
#vi perfmon.sh
date >> /DH_pw450_perf_`hostname`_`date +%m%d`.log
echo "this is iostat's output" >>/DH_pw450_perf_`hostname`_`date +%m%d`.log
iostat -xnp 2 5 >> /DH_pw450_perf_`hostname`_`date +%m%d`.log
echo "this is mpstat's output" >>/DH_pw450_perf_`hostname`_`date +%m%d`.log
mpstat 2 5 >> /DH_pw450_perf_`hostname`_`date +%m%d`.log
echo "this is vmstat's output" >>/DH_pw450_perf_`hostname`_`date +%m%d`.log
vmstat 2 5 >> /DH_pw450_perf_`hostname`_`date +%m%d`.log
3 改變文件屬性
#chmod 777 /perfmon.sh
4 編輯root用戶的crontab文件
#cd /var/spool/cron/crontabs
#vi root
增加以下一行
30 * * * * /perfmon.sh
5 重啟cron進程
#/etc/rc2.d/S75cron stop
#/etc/rc2.d/S75cron start
#crontab -l root
4 結束操作記錄命令
#exit
