1.2 数据说明

• 第一列用户存储线程号，一个完整的用户请求要分为很多步骤，每一个步骤的线程号都是相同的
  但是由于多个用户同时访问服务器，因此一个请求所产生的各个步骤的日志并不是连续打印，而是错落间隔在日志的各部分中
  我们可以通过线程号，来将一个请求的完整内容抽取出来
• 第二列存储时间
• 第三列存储服务器名称，一个系统可能有多个服务器
• eventController：功能的名称
• cpId：加盟店ID

二. 查询

• 查询PMT.payinfoforprc.test.search功能
• 然后通过oldest_data_search=1进一步过滤
• 然后通过awk '{print $1}'获取出第一列(awk默认通过空格分列)
  • ./file1.log:150
  • ./file1.log:160
• 再通过awk -F ":" '{print "^"$2 " " $1}'构造查询key
  • ^150 ./file1.log
  • ^160 ./file1.log
• 再通过xargs -L 1 grep -a 命令，从前面的命令中读取一行输入，并将其作为参数传递给下一个命令grep -a 构造查询命令
  • grep -a ^150 ./file1.log
  • grep -a ^160 ./file1.log
• 最后再从查询的结果中，通过grep -E "SPLREQUEST|MYCODE2005"进一步筛选

grep -a "PMT.payinfoforprc.test.search" ./file*.log | \
grep -a "oldest_data_search=1" | \
awk '{print $1}' | \
awk -F ":" '{print "^"$2 " " $1}' | \
xargs -L 1 grep -a | \
grep -E "SPLREQUEST|MYCODE2005"

2.1 统计每个加盟店搜索的次数

⏹完整命令

• cpId=[^ ]*
  • 查询不为空的cpId
• awk '{$1=$1; print $0}'
  • 清除行中的多余空格。通过重新格式化行
  • awk 会用单个空格替换多个连续的空格

grep -a "PMT.payinfoforprc.test.search" ./file*.log | \
grep -a "oldest_data_search=1" | \
awk '{print $1}' | \
awk -F ":" '{print "^"$2 " " $1}' | \
xargs -L 1 grep -a | \
grep -E "MYCODE2005" | \
grep -o -e "param cpId=[^ ]*" | \
uniq -c | \
awk '{$1=$1; print $0}' | \
sort
