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: 1Pipeline main started12/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: 1Pipeline main started12/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"}
