1.根据访问IP统计UV
awk ‘{print $1}’ access.log|sort | uniq -c |wc -l
2.统计访问URL统计PV
awk ‘{print $7}’ access.log|wc -l
3.查询访问最频繁的URL
awk ‘{print $7}’ access.log|sort | uniq -c |sort -n -k 1 -r|more
4.查询访问最频繁的IP
awk ‘{print $1}’ access.log|sort | uniq -c |sort -n -k 1 -r|more
5.根据时间段统计查看日志
cat access.log| sed -n ‘/14/Mar/2015:21/,/14/Mar/2015:22/p’|more
6.查看Web服务器进程连接数:
netstat -antp | grep 80 | grep ESTABLISHED -c
7.查看Web服务器(Nginx Apache)的并发请求数及其TCP连接状态:
netstat -n | awk ‘/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}’
