...1. 统计每秒请求数量
从大到小排列，取前 5 个最高。
# -F 输入文件分隔符
$ awk -F ',' '{s[$1]+=1} END {for(i in s) print s[i]" "i}' access.log | sort -nr | head -n 5

查看 15:30 这一分钟内各 Action 的请求数量，取最高的 5 个。
$ cat access.log | grep '15:30:' | awk -F ':' '{s[$14]+=1} END {for(i in s) print s[i]" "i}' | sort -nr | head -n 5

23 "/Test1","domain"
22 "/Test2","domain"
5 "/Test3","domain"
5 "/Test4","domain"3. 统计某一时间段内 uwsgi 相应时间过长数量
查看 15:30 这一分钟内 uwsgi 响应超过 500ms 的请求数量。
$ cat access.log | grep '15:30:' | awk -F ':' '{if($10 > 0.5) print $0}' | wc -l
204. 计算平均请求时间
cat access.log | grep '15:30:' | awk -F ':' '{print $10}' | awk -F ',' '{s += $1} END {print s/NR}'
