简简单单 Rails Request log 分析

1. 通过 wvanbergen-request-log-analyzer
安装：
gem sources -a http://gems.github.com
sudo gem install wvanbergen-request-log-analyzer

$ request-log-analyzer /var/log/my_app.log
可以分析大多内容，例如：

Top 10 most requested actions

Top 10 actions by time – cumulative

Top 10 actions by time – per request mean

Top 10 worst DB offenders – cumulative time

Top 10 worst DB offenders – mean time

Requests graph – per hour

2， 得到独立IP数量
cat production.log | grep “^Processing” | awk ‘{print $4}’ | uniq | wc -l

3, 每个IP的访问次数
cat production.log | grep “^Processing” | awk ‘{print $4}’ | uniq -c

4, 得到网站所有访问数量
cat production.log | grep “^Processing” |wc |awk ‘{print $1}’

5, 统计每个页面的各自访问次数
cat production.log |grep “200 OK” | awk ‘{print $17}’ | sort | uniq -c
