TOP 명령 출력에 타임스탬프 추가 [닫기]

날짜/타임스탬프(시간별)/사용자별로 CPU 및 메모리 사용률을 모니터링해야 합니다. 아래 "TOP" 명령에서 시간별 CPU 사용량 보고서를 준비할 수 있도록 날짜/타임스탬프 필드도 추가해야 합니다.

누군가 이 작업을 수행하는 방법을 말해 줄 수 있습니까?

나는 다음과 같은 결과를 얻습니다.

 top | awk 'NR%13==0 { printf  "%d %s\n",  systime(), $0 ; fflush(stdout) }'

아래와 같아야합니다

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

  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
