CPU_USAGE=`top -b -n 1|head -n 5`
MEM_USAGE=`free -m`
HCT=`ps aux| awk '{print $5 "\t" $6 "\t" $11}' |sort -nr|head -n 10`

#setup the time of the check
echo "#######################################################" >> $IOSTAT_FILE
echo "$DATE" >> $IOSTAT_FILE
echo "-------------------------------------------------------------------------" >>$IOSTAT_FILE
#check the cpu status
echo "$CPU_USAGE" >> $IOSTAT_FILE
echo "-------------------------------------------------------------------------" >>$IOSTAT_FILE
#check the memory status
echo "$MEM_USAGE" >> $IOSTAT_FILE
echo "-------------------------------------------------------------------------" >>$IOSTAT_FILE
#check the tasks status
echo "$HCT" >> $IOSTAT_FILE

 

会生成一个iostatus.txt的文件，水平有限还不能根据这些数据给出简明扼要的提示，只能自己看使用率了。
