logstash input监控json文件

1. UTF-8编码，无BOM格式，否则容易乱码

2. 经过压缩的JSON——单行文件

3. 带有line terminators——否则会导致不出发logstash的event

 

通过配置output为：

output {
        stdout {
       codec => json
}

输出：
{"name":"lll","sex":"xxx","age":123,"@version":"1","@timestamp":"2016-03-07T15:51:04.211Z","path":"/home/data/test.json","host":"virtual-machine"}

可以发现，输出的内容也满足以上3个特点。

 

通过配置output为：

output {
        stdout { 
        codec => rubydebug  
#codec =>  json
}

输出：
Logstash startup completed
{
          "name" => "lll",
           "sex" => "xxx",
           "age" => 123,
      "@version" => "1",
    "@timestamp" => "2016-03-07T15:51:43.005Z",
          "path" => "/home/data/test.json",
          "host" => "virtual-machine"
}

可以发现，输出的格式为ruby JSON。
