json - Json文件从Filebeat到Logstash，然后到elasticsearch

Question

我正在尝试提取根据json fileformat生成的库存数据。

{  
   "_meta":{  
      "hostvars":{  
         "host1":{  
            "foreman":{  
               "architecture_id":1,
               "architecture_name":"x86_64",
               "capabilities":[  
                  "build"
               ],
               "certname":"host1",
               "comment":"this is hostname1",
               "created_at":"2017-03-08T15:27:11Z",
               "disk":"10gb",
               "domain_id":5,

            },
            "foreman_facts":{  
               "boardmanufacturer":"Intel Corporation",
               "boardproductname":"440BX Desktop Reference Platform",
               "ipaddress":"1.1.1.1",
               "ipaddress_eth0":"1.1.1.2",
               "ipaddress_lo":"127.0.0.1",

            },
            "foreman_params":{  

            }
         },
         "host2":{  
            "foreman":{  
               "architecture_id":1,
               "architecture_name":"x86_64",
               "capabilities":[  
                  "build"
               ],
               "certname":"host2",
               "comment":"this hostname2",
               "created_at":"2017-03-08T15:27:11Z",
               "disk":"20gb",
               "domain_id":5,

            },
            "foreman_facts":{  
               "boardmanufacturer":"Intel Corporation",
               "boardproductname":"440BX Desktop Reference Platform",
               "ipaddress":"2.1.1.1",
               "ipaddress_eth0":"2.2.2.2",
               "ipaddress_lo":"127.0.0.1",

            },
            "foreman_params":{  

            }
         },
         "foreman_all":[  
            "host3",
            "host4",

         ],
         "foreman_environment: [ 
         "computer1",
         "computer2"
      ],

使用以下代码设法在ElasticSeach中获取数据。

文件节拍配置:

multiline.pattern: '^{'

multiline.negate: true

multiline.match: after

output.logstash:
  # The Logstash hosts
 hosts: ["localhost:5044"]

Logstash:

 input {
 beats {
        port => "5044"
       }

}

output {

elasticsearch {
        hosts => [ "10.1.7.5:9200" ]
index => "inventory-%{+YYYY-MM-dd}"
}
stdout {}

}

但是我注意到filebeat将整个json文件视为一条消息。想知道我是否可以中断消息，仅发送 hostvars 部分并根据每个 主机名索引文档，而忽略上述json数据中的 foreman_all 和 foreman_environment 字段。上面是示例数据，我必须提取大约10万条记录，因此要确保我在网络上发送的数据尽可能少。

我想在Elasticsearch中以以下格式摄取数据。想知道是否有人可以建议使用最佳配置。

flex 文件ID 1

computer name : "host1"
"architecture_id": 1,
"architecture_name": "x86_64",
"capabilities": ["build"],
"Company hardware name": "host1",
"comment": "this is hostname1",
"created_at": "2017-03-08T15:27:11Z",
"disk": "10gb",
"domain_id": 5,
"foreman_facts": {
"boardmanufacturer": "Intel Corporation",
"boardproductname": "440BX Desktop Reference Platform",
"ipaddress": "1.1.1.1",
"ipaddress_eth0": "1.1.1.2",
"ipaddress_lo": "127.0.0.1",

flex 文件ID 2

"computer name"" : "host2"
"architecture_id": 1,
"architecture_name": "x86_64",
"capabilities": ["build"],
"certname": "host2",
"comment": "this hostname2",
"created_at": "2017-03-08T15:27:11Z",
"disk": "20gb",
"domain_id": 5,
"boardmanufacturer": "Intel Corporation",
"boardproductname": "440BX Desktop Reference Platform",

首先，您应该像这样在filebeat.yml中设置document_type:

filebeat:
    prospectors:
        - input_type: log
    paths:
        - "/home/ubuntu/data/test.json"
    document_type: json
    json.message_key: log
    json.keys_under_root: true
    json.overwrite_keys: true

看看这可能会有帮助: https://www.elastic.co/blog/structured-logging-filebeat

然后您可以在logstash中获取json值并将其设置为新字段(在logstash.conf中配置):

json  {
      source => "parameter"
      target => "parameterData"
      remove_field => "parameter"
}

您可以在logstash中使用std_in和std_out进行测试。
