关于logstash-out-mongodb插件说明

从kafka获取数据，存到mongodb中。适合空间查询geo_point设置。配置文件如下：

input {
  kafka {
    type => "test"
    auto_offset_reset => "smallest"
    group_id => "m2"
    topic_id => "db100"
    zk_connect => "192.168.199.6:2181,192.168.199.7:2181,192.168.199.8:2181"
  }
}

filter {
  mutate {
    split => { "message" => "," }
      add_field => {
                "id" => "%{message[1]}"
                "SYZTDM_s" => "%{message[55]}"
                "lat" => "%{message[6]}"
                "lon" => "%{message[7]}"
                "loc" =>  "%{message[6]}"
     }
     remove_field => [ "message" ]
     remove_field => [ "path" ]
     remove_field => [ "host" ]
     remove_field => [ "type" ]
}
mutate{
 convert => {"lat" => "float"}
 convert => { "lon" => "float"}
 convert => {"loc" => "float"}

}
mutate{
    merge => {"loc" =>"lon"}
}
}

output {
mongodb {
        collection => "base"
        database => "fragment"

uri => "mongodb://192.168.199.7:27017"
       }
}

注意：

1.logstash需要安装mongodb插件，默认没有安装的。（bin/logstash-plugin install logstash-output-mongodb）

2.插入方式是insert方式，是单个插入。

3.geo_point查询方式是数组类型的。
