logstash date插件介绍

时间处理(Date)

之前章节已经提过，

filters/date 插件可以用来转换你的日志记录中的时间字符串，变成 LogStash::Timestamp 对象，然后转存到 @timestamp 字段里

output {
      if   [type] == "zj_frontend_access"{
        elasticsearch {
                hosts => "192.168.32.80:9200"
                index => "logstash-zjzc-frontend-%{+YYYY.MM.dd}"
        }
		stdout {
			codec => rubydebug
		}
      }
      else if  [type] == "wj_frontend_access"{
      elasticsearch {
                hosts => "192.168.32.81:9200"
                index => "logstash-wj-frontend-%{+YYYY.MM.dd}"
        }
                stdout {
                        codec => rubydebug
                } 

  }

}

注意：因为在稍后的 outputs/elasticsearch 中常用的 %{+YYYY.MM.dd} 这种写法必须读取 @timestamp 数据，

所以一定不要直接删掉这个字段保留自己的字段，而是应该用 filters/date 转换后删除自己的字段！

[elk@zjtest7-frontend config]$ ../bin/logstash -f stdin02.conf
Settings: Default pipeline workers: 1
Pipeline main started
12/Sep/2016:21:32:33 +0800
{
       "message" => "12/Sep/2016:21:32:33 +0800",
      "@version" => "1",
    "@timestamp" => "2016-09-13T02:00:19.890Z",
          "host" => "0.0.0.0",
       "logdate" => "12/Sep/2016:21:32:33 +0800"
}

[elk@zjtest7-frontend config]$ cat stdin02.conf
input {
    stdin {
    }
}

filter {
    grok {
        match => ["message", "%{HTTPDATE:logdate}"]
    }
#    date {
#        match => ["logdate", "dd/MMM/yyyy:HH:mm:ss Z"]
#        add_field =>["response_time","%{logdate}"]
#    }
}
output {
 stdout {
  codec=>rubydebug{}
   }
 }

 使用date插件:
 [elk@zjtest7-frontend config]$ cat stdin02.conf
input {
    stdin {
    }
}

filter {
    grok {
        match => ["message", "%{HTTPDATE:logdate}"]
    }
    date {
        match => ["logdate", "dd/MMM/yyyy:HH:mm:ss Z"]
        add_field =>["response_time","%{logdate}"]
    }
}
output {
 stdout {
  codec=>rubydebug{}
   }
 }

[elk@zjtest7-frontend config]$ ../bin/logstash -f stdin02.conf
Settings: Default pipeline workers: 1
Pipeline main started
12/Sep/2016:21:32:33 +0800
{
          "message" => "12/Sep/2016:21:32:33 +0800",
         "@version" => "1",
       "@timestamp" => "2016-09-12T13:32:33.000Z",
             "host" => "0.0.0.0",
          "logdate" => "12/Sep/2016:21:32:33 +0800",
    "response_time" => "12/Sep/2016:21:32:33 +0800"
}
