我正在尝试弄清楚如何将_timestamp与logstash一起使用。
我试图添加到映射:
"_timestamp" : {
"enabled" : true,
"path" : "@timestamp"
},
但这没有预期的效果。我在elasticsearch-template.json
文件中执行此操作(我尝试使用和不使用"store"=true
):
{
"template" : "logstash-*",
"settings" : {
"index.refresh_interval" : "5s"
},
"mappings" : {
"_default_" : {
"_timestamp" : {
"enabled" : true,
"store" : true,
"path" : "@timestamp"
},
"_all" : {"enabled" : true},
"dynamic_templates" : [ {
.....
我将修改后的文件添加到输出过滤器
output {
elasticsearch_http {
template => '/tmp/elasticsearch-template.json'
host => '127.0.0.1'
port=>9200
}
}
为了确保数据库是干净的,我反复做:
curl -XDELETE http://localhost:9200/logstash*
curl -XDELETE http://localhost:9200/_template/logstash
rm ~/.sincedb_*
然后我尝试导入我的日志文件。但由于某些原因,_timestamp
未设置。
映射似乎没问题
{
"logstash-2014.03.24" : {
"_default_" : {
"dynamic_templates" : [ {
"string_fields" : {
"mapping" : {
"index" : "analyzed",
"omit_norms" : true,
"type" : "string",
"fields" : {
"raw" : {
"index" : "not_analyzed",
"ignore_above" : 256,
"type" : "string"
}
}
},
"match" : "*",
"match_mapping_type" : "string"
}
} ],
"_timestamp" : {
"enabled" : true,
"store" : true,
"path" : "@timestamp"
},
"properties" : {
"@version" : {
"type" : "string",
"index" : "not_analyzed",
"omit_norms" : true,
"index_options" : "docs"
},
"geoip" : {
"dynamic" : "true",
"properties" : {
"location" : {
"type" : "geo_point"
}
}
}
}
},
"logs" : {
"dynamic_templates" : [ {
"string_fields" : {
"mapping" : {
"index" : "analyzed",
"omit_norms" : true,
"type" : "string",
"fields" : {
"raw" : {
"index" : "not_analyzed",
"ignore_above" : 256,
"type" : "string"
}
}
},
"match" : "*",
"match_mapping_type" : "string"
}
} ],
"_timestamp" : {
"enabled" : true,
"store" : true,
"path" : "@timestamp"
},
"properties" : {
"@timestamp" : {
"type" : "date",
"format" : "dateOptionalTime"
},
数据库中的文档看起来像
{
"_id": "Cps2Lq1nTIuj_VysOwwcWw",
"_index": "logstash-2014.03.25",
"_score": 1.0,
"_source": {
"@timestamp": "2014-03-25T00:47:09.703Z",
"@version": "1",
"created": "2014-03-25 01:47:09,703",
"host": "macbookpro.fritz.box",
"message": "2014-03-25 01:47:09,703 - Starting new HTTP connection (1): localhost",
"path": "/Users/scharf/git/ckann/annotator-store/logs/requests.log",
"text": "Starting new HTTP connection (1): localhost"
},
"_type": "logs"
},
为什么_timestamp
未设置???
答案 0 :(得分:2)
简而言之,它确实有效。
我测试了你的确切场景,以及我发现的内容:
启用_source并从_timestamp
中的某个路径指定_source
时,
您永远不会将_timestamp
视为文档的一部分,但是如果您添加了?fields
查询字符串部分,例如:
http://<localhost>:9200/es_test_logs/ESTest1/ilq4PU3tR9SeoLo794wZlg?fields=_timestamp
您将获得正确的_timestamp
值。
如果您在外部(_timestamp
文档中)传递_source
而不是使用路径,则会在文档的_timestamp
属性下看到_source
正常
如果您停用_source
字段,则您在文档中根本看不到任何属性,即使是那些您设置为&#34; store" : true
的属性。只有在指定?fields
或构建返回这些字段的查询时,才会看到它们。
