Logstash日期过滤器不使用Apache时间戳更新@timestamp

Question

我正在尝试使用logstash回填一些过去的Apache访问日志数据,因此我需要将事件@timestamp设置为出现在日志消息中的日期.这是我当前的logstash配置:

input {
    tcp {
        type => "access_log"
        port => 9293
    }
}

filter {

    grok {
      match => { "message" => "%{COMBINEDAPACHELOG}" }
    }

    date {
      # Try to pull the timestamp from the 'timestamp' field (parsed above with
      # grok). The apache time format looks like: "18/Aug/2011:05:44:34 -0700"
      locale => "en"
      timezone => "America/New_York"
      match => { "timestamp" => "dd/MMM/yyyy:HH:mm:ss Z" }
      add_tag => [ "tsmatch" ]
    }

}

output {
  stdout { codec => rubydebug }
}

但是,日期过滤器似乎不会更新事件@timestamp,即使正确捕获了Apache时间戳并且正则表达式应该匹配它.输出数据如下所示:

{
        "message" => "56.116.21.231 - - [20/Nov/2013:22:47:08 -0500] \"GET /xxxx/1.305/xxxx/xxxx.zip HTTP/1.1\" 200 33002333 \"-\" \"xxxxx/3.0.3 CFNetwork/609.1.4 Darwin/13.0.0\"",
     "@timestamp" => "2013-12-01T12:54:27.920Z",
       "@version" => "1",
           "type" => "access_log",
           "host" => "0:0:0:0:0:0:0:1%0:51045",
       "clientip" => "56.116.21.231",
          "ident" => "-",
           "auth" => "-",
      "timestamp" => "20/Nov/2013:22:47:08 -0500",
           "verb" => "GET",
        "request" => "/xxxx/1.305/xxxx/xxxx.zip",
    "httpversion" => "1.1",
       "response" => "200",
          "bytes" => "33002333",
       "referrer" => "\"-\"",
          "agent" => "\"xxxxx/3.0.3 CFNetwork/609.1.4 Darwin/13.0.0\"",
           "tags" => [
        [0] "tsmatch"
    ]
}

关于什么可能出错的任何想法？

我正在使用logstash-1.2.2 flatjar.

好的,我发现了问题,我在匹配操作中使用了错误的语法:

match => ["timestamp","dd/MMM/yyyy:HH:mm:ss Z"]

不

match => {"timestamp"=>"dd/MMM/yyyy:HH:mm:ss Z"}
