一、nginx日志格式
log_format main ‘$remote_addr – $remote_user [$time_iso8601] “$request” ‘
‘$status $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” “$http_x_forwarded_for” ‘
‘ “$upstream_addr” “$upstream_status” “$request_time” ‘;
二、nginx访问日志（/var/log/nginx）
12.124.127.44 – – [29/Jul/2014:20:54:20 +0800] “GET / HTTP/1.1″ 200 211 “-” “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)” “-” “127.0.0.1:8081″ “200” “0.001”
115.29.113.101 – – [29/Jul/2014:20:54:22 +0800] “GET / HTTP/1.1″ 200 211 “-” “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)” “-” “127.0.0.1:8081″ “200” “0.005”
112.124.127.53 – – [29/Jul/2014:20:56:49 +0800] “GET / HTTP/1.1″ 200 211 “-” “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)” “-” “127.0.0.1:8081″ “200” “0.002”
112.124.127.44 – – [29/Jul/2014:20:59:20 +0800] “GET / HTTP/1.1″ 200 211 “-” “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)” “-” “127.0.0.1:8081″ “200” “0.002”
115.29.113.101 – – [29/Jul/2014:20:59:22 +0800] “GET / HTTP/1.1″ 200 211 “-” “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)” “-” “127.0.0.1:8081″ “200” “0.002”
三、nginx日志分析
1、打印响应时间并且去除引号
cat website.access.log| awk ‘{print $(NF)}’ | awk -F “”” ‘{print $2′}>a.txt
2、合并文件，将时间重新补上去
paste -d ” ” website.access.log a.txt > b.txt
3、查找响应时间大于1秒的url
cat b.txt |awk ‘($NF>1){print $6$7 ” ” $NF}’>c.txt
4、hsell脚本
vi loganalysis.sh
cat $1 | awk ‘{print $(NF)}’ | awk -F “”” ‘{print $2′} >a.txt
paste -d ” ” $1 a.txt > b.txt
cat b.txt |awk ‘($NF>1){print $1$4$6$7 ” ” $NF}’ >$2
使用：
./loganalysis.sh 日志
绝对路径 新建
日志文件名
