awk分析日志获取页面执行时间
一、web日志文件格式
59.233.33.24 - - [09/Oct/2010:04:04:03 +0800] GET /pages/international/tejia.php HTTP/1.1 "200" 15708 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Sicent; WoShiHoney.B; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)" "-" 0.037
#按照空格分隔，最后一个字段[0.037] 是页面执行时间，第7个字段 是页面访问地址。
二、awk命令脚本
awk 'BEGIN{
print "Enter log file:"; getline logs; #logs="/var/log/nginx/access.log-20101008"; OFMT="%.3f"; while(getline < logs) { split($7,atmp,"?"); aListNum[atmp[1]]+=1; aListTime[atmp[1]]+=$NF; ilen++; } close(logs); print "\r\ntotal:",ilen,"\r\n========\r\n"; for(k in aListNum) { print k,aListNum[k],aListTime[k]/aListNum[k] | "sort -r -n -k3"; } }'
