Mysql：mysqldumpslow 技巧：如何不截断 slow.log 文件，直接指定开始starttime时间、stoptime结束时间，进行分析？

sed -n '/Time: 2022-12-20/,/Time: 2022-12-21/p' /data/mysql/slow.log | mysqldumpslow -s at -n 10 - | more
sed -n '/Time: 2022-12-20/,/Time: 2022-12-21/p' /data/mysql/slow.log | mysqldumpslow -s at -n 10 - | more
sed -n '/Time: 2022-12-20/,/Time: 2022-12-21/p' /data/mysql/slow.log | mysqldumpslow -s at -n 10 - | more

grep -A 999999999 "Time: 2022-12-20" /data/mysql/slow.log | grep -B 999999999 "Time: 2022-12-21" /data/mysql/slow.log | mysqldumpslow -s at -n 10 - | more

#!/sh/awk

  }
  if (i==1) {
    j++;
    print $0;
    if ($0 ~ /# Time: 2022-12-21.*/) i=0;
  }
}

END {
  print "lines: " j;
