前期博客
Filebeat啊,根据input来监控数据,根据output来使用数据!!!
请移步,
Filebeat之input和output(包含Elasticsearch Output 、Logstash Output、 Redis Output、 File Output和 Console Output)
Logstash啊,根据input来监控数据,根据output来使用数据!!!
手把手带你看官方文档(Logstash inputs和Logstash outputs)
https://www.elastic.co/guide/index.html
https://www.elastic.co/guide/en/logstash/index.html
https://www.elastic.co/guide/en/logstash/2.4/index.html
关于 Logstash inputs、Logstash outputs和Filter plugins,很多很多,自行去官网看,我这里不多赘述。仅仅拿下面来示范:
Logstash 的input
file input
最常用的input插件是file。

这个,是可以自定义的。我这里是
path => "/home/hadoop/app.log"
或者
path => [ "/home/hadoop/app", "/home/hadoop/*.log" ]
input {
file {
path => "/home/hadoop/app.log"
}
}
filter {
}
output {
stdout {}
}
我这里是, 监控/home/hadoop/app.log这个文件的变化。

其实,这个文件,.sincedb_8f3299d0a5bdb7df6154f681fc150341也会记录。
注意:
第一次读取新文件,不会有.sincedb等这些,默认根据这个start_position去读,若start_position是end,则读最后。若start_position是begin,则读最开始。
若不是第一次读取文件了,重启Logstash,则会有.sincedb文件了,则就转去根据这个.sincedb文件读了。不管start_position是什么,都不起效了。
start_position:指定从什么位置开始读取文件数据,默认是结束位置,也可以指定为从头开始。
注意:start_position仅在该文件从未被监听过的时候起作用,因为logstash在读取文件的时候会记录一个.sincedb文件来跟踪文件的读取位置,当文件被读取过一次之后,下次就会从.sincedb中记录的位置读取,start_position参数就无效了。文件默认在用户目录下。
注意一个坑:ignore_older属性,表示忽略老的数据,值默认为86400,表示忽略24小时以前的数据。如果你新监控一个24小时以上没有被修改过的老文件的话,就算把start_position设置为beginning,也无法获取之前的数据。

elasticsearch output
即把Logstash里的数据,写到elasticsearch 集群(这台192.168.80.10里)
hosts=>"192.168.80.00"
或
hosts=>["192.168.80.10:9200","192.168.80.11:9200","192.168.80.12:9200"]
1.x中属性名称叫host
默认向es中创建的索引库是logstash-%{+YYYY.MM.dd},可以利用es中的索引模板特性定义索引库的一些基础配置。
input {
stdin { }
}
filter {
}
output {
elasticsearch {
hosts => "192.168.80.10:9200"
}
}
