nginx日志打印响应时间

日志格式：
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for "$request_time"';
配置:
server {
server_name test.com;
root html;
index index.html;
access_log logs/access.log main;

}

可以为做性能测试统计平均时间

awk '{sum+=$10;count+=1} END{print "SUM:"sum"\nAVG:"sum/count"\nCOUNT:"count}' access_log2012-08-24.16.log


awk '{a_array[$1]+=$10;b_array[$1]++}END{for(i in a_array) print i":"a_array[i]":"b_array[i]}' access_log2012-08-24.16.log
