将时间戳添加到 TOP 命令输出

我需要按日期/时间戳（每小时）监视 CPU 和内存利用率/用户。在下面的“TOP”命令中，我还需要添加日期/时间戳字段，以便我可以准备每小时的 CPU 使用情况报告

有人可以告诉我该怎么做吗？

我得到如下输出

 top | awk 'NR%13==0 { printf  "%d %s\n",  systime(), $0 ; fflush(stdout) }'
1486713976     1 root      20   0 10560  844  708 S      0  0.0   0:32.48 init

需要像下面这样

top | awk 'NR%13==0 { printf  "%d %s\n",  systime(), $0 ; fflush(stdout) }'
02-10-2017-16:01:58     1 root      20   0 10560  844  708 S      0  0.0   0:32.48 init

02-10-2017-16:02:00    28 root      RT   0     0    0    0 S      0  0.0   0:11.59 watchdog/5

答案1

top -b1 -n1 | awk -vtime="$(date +%m-%d-%Y-%T)" 'NR<7{print;next}NR==7{printf("Time\t\t\t\t%s\n",$0)}NR>8{printf("%s\t%s\n",time,$0)}' > cpu.txt


top -b1 -n1 -- gives the top output and come back to terminal
-vtime="$(date +"%m-%d-%Y-%T)"  -- store the current time to variable called time
NR<7{print;next} -- read the lines from 1 to 6 and print it. 
NR==7{printf("Time\t\t\t\t%s\n",$0)}  -- if it is 7th line, then add Time as first column
NR>8{printf("%s\t%s\n",time,$0)}'  -- add the calculated time in first field

答案2

  top -n 1 -b | grep -Ev "Tasks:|Swap:|Cpu|Mem:" > top_file
  grep "PID" top_file > top_test
  sed -i '/PID/d;/top/d;/^$/d' top_file
  awk '{print strftime("%m-%d-%Y-%H:%M:%S", systime())" " $0}' top_file > top_final
  sed -i "s/./timestamp /1" top_test 
  cat top_final >> top_test
  sed -i 's/( )*/\1/g;s/ /,/g' top_test
