elasticsearch - Logstash logdate类型问题

我想将“logdate”类型记录为日期，但是即使在应用日期过滤器后，我也将“logdate”类型记录为字符串。这是我的过滤器:

filter {
    grok {
         match => { "message" => "%{TIMESTAMP_ISO8601:logdate}\s%{LOGLEVEL:level} +: +%{WORD:USE_CASE} +: +%{WORD:STEP_DETAIL} +: +\[%{WORD:CIN}\] +: +(?<MID>([^\s]+)) +: +%{GREEDYDATA:MESSAGE_DETAILS}" }
         add_field => [ "received_at", "%{@timestamp}" ]
         add_field => [ "received_from", "%{host}" ]
         add_tag => [ "level:%{level}" ]
         add_tag => [ "USE_CASE:%{USE_CASE}" ]
         add_tag => [ "CIN:%{CIN}" ]
         add_tag => [ "MID-%{MID}" ]
        }
    date {
        match => [ "logdate", "yyyy-MM-dd HH:mm:ss,SSS" ]
           target => "@timestamp"
      }
    }

这是我点击命令后得到的映射

curl -XGET localhost:9200/_mapping?pretty

映射:

  "logdate" : {
    "type" : "string",
    "norms" : {
      "enabled" : false
    },
    "fields" : {
      "raw" : {
        "type" : "string",
        "index" : "not_analyzed",
        "ignore_above" : 256
      }
    }
  },

我在哪里做错了？有什么建议吗？

最佳答案

如果希望logdate字段为日期字段，则需要使其成为target过滤器的date

date {
   match => [ "logdate", "yyyy-MM-dd HH:mm:ss,SSS" ]
   target => "logdate"
}

这不会将@timestamp设置为同一件事，因此您可能需要再次设置@timestamp。
