elasticsearch - ELK中的日期时间解析

Question

我正在尝试使用ELK堆栈解析日志。以下是我的示例日志

2015-12-11 12:05:24+0530 [process] INFO: process 0.24.5 started 

我正在使用以下grok

grok{
    match => {"message" => "(?m)%{TIMESTAMP_ISO8601:processdate}\s+\[%{WORD:name}\]\s+%{LOGLEVEL:loglevel}"}
    }

我的 Elasticsearch 映射是

{
    "properties": {
        "processdate":{
            "type":   "date",
            "format" : "yyyy-MM-dd HH:mm:ss+SSSS"
        },
        "name":{"type" : "string"},
        "loglevel":{"type" : "string"},
    }
}

但是当加载到Elastic search中时，我遇到了错误，

 "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse [processdate]", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"Invalid format: \"2015-12-11 12:05:39+0530\" is malformed at \" 12:05:39+0530\""}}}}, :level=>:warn}

如何将其修改为适当的数据格式？我在 Elasticsearch 中添加了正确的日期格式。

更新: localhost:9200 / log

{"log":{"aliases":{},"mappings":{"filelog":{"properties":{"processdate":{"type":"date","format":"yyyy-MM-dd' 'HH:mm:ssZ"},"loglevel":{"type":"string"},"name":{"type":"string"}}}},"settings":{"index":{"creation_date":"1458218007417","number_of_shards":"5","number_of_replicas":"1","uuid":"_7ffuioZS7eGBbFCDMk7cw","version":{"created":"2020099"}}},"warmers":{}}}

您收到的错误表示您的日期格式不正确。固定这样的日期格式，即在结尾处使用Z(时区)，而不是+SSSS(秒数):

{
    "properties": {
        "processdate":{
            "type":   "date",
            "format" : "yyyy-MM-dd HH:mm:ssZ"
        },
        "name":{"type" : "string"},
        "loglevel":{"type" : "string"}
    }
}

另外，根据我们之前的交流，您的elasticsearch输出插件缺少document_type设置，因此应这样配置，以便利用您的自定义filelog映射类型(否则，将使用默认的logs类型，而您的自定义映射类型为没踢):

output {
    elasticsearch {
        hosts => ["172.16.2.204:9200"] 
        index => "log" 
        document_type => "filelog" 
    } 
}
