1、Nginx經過$upstream_response_time $request_time統計請求和後臺服務響應時間html
nginx.conf使用配置方式:linux
log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"' '$connection $upstream_addr ' 'upstream_response_time $upstream_response_time request_time $request_time ';nginx
$request_time和$upstream_response_time之間差異:apache
$request_time包含了用戶數據接收時間,而真正程序的響應時間應該用$upstream_response_time 因此若是用戶網絡較差,或者傳遞數據較大時,$request_time會比$upstream_response_time大不少 詳細參考:http://wuzhangshu927.blog.163.com/blog/static/114224687201310674652147/tomcat
2、Tomcat經過%D或%T統計請求響應時間網絡
server.xml使用配置方式 <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u [%{yyyy-MM-dd HH:mm:ss}t] %{X-Real_IP}i "%r" %s %b %D %F" />spa
%D - 官方解釋:Time taken to process the request, in millis,處理請求的時間,以毫秒爲單位 %T - 官方解釋:Time taken to process the request, in seconds,處理請求的時間,以秒爲單位 %F - 官方解釋:Time taken to commit the response, in millis,提交響應的時間,以毫秒爲單位 詳細說明:http://tomcat.apache.org/tomcat-7.0-doc/config/valve.html#Access_Logging日誌
3、經過awk命令輔助統計access.logorm
1.簡單統計nginx訪問日誌access log每分鐘請求數server
awk -F: '{count[$2":"$3]++} END {for (minute in count) print minute, count[minute]}' /usr/local/nginx/logs/access.log | sort > count.log
結果以下所示(count.log) 18:30 2086 18:31 2184 18:32 2176 18:33 2122 18:34 2128 18:35 2179 ...
參考:http://huoding.com/2013/01/26/215
2.統計請求響應時間超過10s的記錄
awk '($NF > 10){print $0}' /usr/local/tengine/logs/cut-log/access_2015-01-12.log >t10_0112.log
