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。
