命令修改

命令修改

我使用以下命令来获取日志文件中每秒的最高请求数,并且效果很好。

grep "2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c | sort -n | tail -n1

现在我还想获得每秒最小的请求以及最高数量停留的时间。例如:假设命令的结果是 2000,这是日志文件中每秒的最高请求,我想知道 2000 个请求持续了多长时间?换句话说:如果2000年的峰值发生了,我想知道这个峰值需要多长时间才能下降。

这是日志文件的一部分:

以下是获取最多点击持续时间的一种方法:

highest为原始命令分配一个变量:*^添加 grep 模式,将匹配限制为行开头的日期。

  highest=$(grep "^2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c | sort -n | tail -n1)  

再次使用原始命令,最多uniq,将完整uniq计数列表重定向到tempfile

  grep "^2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c >tempfile  

tempfile使用grep 搜索 new 中的最大数字,-A1以获取之后的第一行:

  grep -A1 "^$highest" tempfile | tail -n1  

您可以使用分号 (;) 将它们组合成一行,如下所示:

  highest=$(grep "^2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c | sort -n | tail -n1);grep "^2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c >tempfile;grep -A1 "^$highest" tempfile | tail -n1

如果您需要对实际时间差的输出进行日期时间数学运算,则可以将迄今为止的结果捕获到变量中nexttime

  nexttime=$(highest=$(grep "^2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c | sort -n | tail -n1);grep "^2017-02-22" "LogFile.log" | cut -c1-20 | uniq -c >tempfile;grep -A1 "^$highest" tempfile | tail -n1)

并用它来计算差异:

  highest=$(echo $highest | cut -d' ' -f 3)              # get the time field (#3)
  nexttime=$(echo $nexttime | cut -d' ' -f 3)            # get the time field (#3)
  logStart=$(date -u -d "$highest" +"%s")                # convert to seconds
  logEnd=$(date -u -d "$nexttime" +"%s")                 # convert to seconds
  date -u -d "0 $logEnd sec - $logStart sec" +"%H:%M:%S" # display time difference

同样,您可以使用分号 (;) 将这些语句与上面的其他语句组合起来,或者将其全部放入脚本中。
