LTSV

ltsv 解析器允许解析 LTSV 格式的文本。

Labeled Tab-separated Values 带标签的制表符分隔值(LTSV 格式是 Tab 分隔的值(TSV)的变体。LTSV 文件中的每个记录都用单行表示。每个字段都由 Tab 分隔并具有标签和值。标签和值之间使用 “:” 分隔。

这是一个如何在 apache access log 中使用此格式的示例:

在 httpd.conf 中进行配置

  1. LogFormat "host:%h\tident:%l\tuser:%u\ttime:%t\treq:%r\tstatus:%>s\tsize:%b\treferer:%{Referer}i\tua:%{User-Agent}i" combined_ltsv
  2. CustomLog "logs/access_log" combined_ltsv

parser.conf 配置如下:

  1. [PARSER]
  2.     Name        access_log_ltsv
  3.     Format      ltsv
  4.     Time_Key    time
  5.     Time_Format [%d/%b/%Y:%H:%M:%S %z]
  6.     Types       status:integer size:integer

对于上述定义的解析器来说，以下日志记录是有效的:

  1. host:127.0.0.1  ident:- user:-  time:[10/Jul/2018:13:27:05 +0200]       req:GET / HTTP/1.1      status:200      size:16218      referer:http://127.0.0.1/       ua:Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0

处理后，在内部表示为:

  1. [1531222025.000000000, {"host"=>"127.0.0.1", "ident"=>"-", "user"=>"-", "req"=>"GET / HTTP/1.1", "status"=>200, "size"=>16218, "referer"=>"http://127.0.0.1/", "ua"=>"Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0"}]
