1，查看apache进程
ps aux | grep httpd | grep -v grep | wc -l
2，查看80端口的tcp连接
netstat -tan | grep “ESTABLISHED” | grep “:80″ | wc -l
3，通过日志查看当天ip连接数，过滤重复
cat access_log | grep “20/Oct/2008″ |
linuxjishu/13830.html target=_blank class=infotextkey>awk ‘{print $2}’ | sort | uniq -c | sort -nr
4，当天ip连接数最高的ip (原来是蜘蛛)
cat access_log | grep “20/Oct/2008:00″ | grep “122.102.7.212″ | awk ‘{print $8}’ | sort | uniq -c | sort -nr | head -n 10
5，当天访问页面排前10的url
cat access_log | grep “20/Oct/2008:00″ | awk ‘{print $8}’ | sort | uniq -c | sort -nr | head -n 10
6，用tcpdump嗅探80端口的访问看看谁最高
tcpdump -i
eth0 -tnn dst port 80 -c 1000 | awk -F”.” ‘{print $1″.”$2″.”$3″.”$4}’ | sort | uniq -c | sort -nr
然后，查看日志中IP地址行为：
cat access_log | grep 122.102.7.212| awk '{print $1"t"$8}' | sort | uniq -c | sort -nr | less
7，查看某一时间段的ip连接数
grep "2006:0[7-8]" www20060723.log | awk '{print $2}' | sort | uniq -c| sort -nr | wc
