Linux 下统计Apache每分钟的并发数

脚本非常简单，不清楚原理，逐行运行即可。

使用时将脚本复制到home目录，并添加执行权限、定时任务即可。

代码内容如下：

#!/bin/sh
date >> /home/date-time.txt
sed ‘s/$/& Apache complicating No./g‘ /home/date-time.txt > /home/date-time2.txt
echo | netstat -na | grep ESTABLISHED | wc -l > /home/Connection-No.txt
paste /home/date-time2.txt  /home/Connection-No.txt >>/home/Connections.txt
rm -rf /home/date-time.txt
rm -rf /home/date-time2.txt
rm -rf /home/Connection-No.txt

#  */1 * * * * /bin/bash /home/connection.sh
