logstash之output插件-输出数据到控制台、file文件、elasticsearch、redis

output插件是经过了input，然后过滤结构化数据之后，接下来我们需要借助output传到我们想传到的地方.output相当于一个输出管道。

将采集数据标准输出到控制台

配置示例

output {stdout {codec => rubydebug}
}

演示：

input {stdin{}}
output {stdout {codec => rubydebug}
}

启动：bin/logstash -f /usr/local/elk/logstash-5.5.2/conf/template/stdout.conf
展示：

将采集数据保存到file文件中

需求：将数据采集到logstash的日志文件中，区分业务和采集日期（哪天采集的）

input {stdin{}}
output {file {path => "/usr/local/elk/logstash-5.5.2/logs/stdout/mobile-collection/%{+YYYY-MM-dd}-%{host}.txt"codec => line {format => "%{message}"}gzip => true}
}

启动：
bin/logstash -f /usr/local/elk/logstash-5.5.2/conf/template/stdout_file.conf
结果展示：

将采集数据保存到Elasticsearch

Logstash可以直接将采集到的信息下沉到elasticsearch中

input {stdin{}}
output {elasticsearch {hosts => ["hadoop01:9200"]index => "logstash-%{type}-%{+YYYY.MM.dd}"flush_size => 20000.  #做批次执行，当数据量达到20000条以后，才会落地到es中idle_flush_time => 10 #当时间达到10S ，我们就落地到es中user => elasticpassword => changeme}
}

启动：bin/logstash -f /usr/local/elk/logstash-5.5.2/conf/template/stdout_es.conf
向控制台中输入6条数据：

然后在kibana上查看，是否logstash已经把数据采集到了elasticsearch

将采集的数据保存到redis

配置：

input { stdin {} }
output {redis {host => "hadoop01"data_type => "list"port => "6379"db => 6key => "logstash-redis-%{+yyyy.MM.dd}"batch=> true.  #开启批处理batch_events=> 10000  #批处理的大小batch_timeout=> 3   #批处理的超时时间#防止OOM---》listcongestion_interval => 3congestion_threhold => 100}
}

启动redis
将数据打入logstash控制台：

去redis上做认证，查看是否已经存储redis中：
