Serilog HTTP接收器+Logstash：将Serilog消息数组拆分为单独的日志事件

我们正在使用Serilog HTTP 接收器将消息发送到 Logstash。但是HTTP消息体是这样的：

{
  "events": [
    {
      "Timestamp": "2016-11-03T00:09:11.4899425+01:00",
      "Level": "Debug",
      "MessageTemplate": "Logging {@Heartbeat} from {Computer}",
      "RenderedMessage": "Logging { UserName: \"Mike\", UserDomainName: \"Home\" } from \"Workstation\"",
      "Properties": {
        "Heartbeat": {
          "UserName": "Mike",
          "UserDomainName": "Home"
        },
        "Computer": "Workstation"
      }
    },
    {
      "Timestamp": "2016-11-03T00:09:12.4905685+01:00",
      "Level": "Debug",
      "MessageTemplate": "Logging {@Heartbeat} from {Computer}",
      "RenderedMessage": "Logging { UserName: \"Mike\", UserDomainName: \"Home\" } from \"Workstation\"",
      "Properties": {
        "Heartbeat": {
          "UserName": "Mike",
          "UserDomainName": "Home"
        },
        "Computer": "Workstation"
      }
    }
  ]
}

IE。日志记录事件在数组中进行批处理。可以一条一条地发送消息，但它仍然是一个单项数组。

然后该事件在 Kibana 中显示为具有字段message有价值

{
  "events": [
    {
      // ...
    },
    {
      // ...
    }
  ]
}

IE。字面意思是来自 HTTP 输入的内容。

如何拆分项目中的项目events数组到各个日志记录事件并将属性“拉”到顶层，以便我在 ElasticSearch 中拥有两个日志记录事件：

  "Timestamp": "2016-11-03T00:09:11.4899425+01:00",
  "Level": "Debug",
  "MessageTemplate": "Logging {@Heartbeat} from {Computer}",
  "RenderedMessage": "Logging { UserName: \"Mike\", UserDomainName: \"Home\" } from \"Workstation\"",
  "Properties": {
    "Heartbeat": {
      "UserName": "Mike",
      "UserDomainName": "Home"
    },
    "Computer": "Workstation"
  }

  "Timestamp": "2016-11-03T00:09:12.4905685+01:00",
  "Level": "Debug",
  "MessageTemplate": "Logging {@Heartbeat} from {Computer}",
  "RenderedMessage": "Logging { UserName: \"Mike\", UserDomainName: \"Home\" } from \"Workstation\"",
  "Properties": {
    "Heartbeat": {
      "UserName": "Mike",
      "UserDomainName": "Home"
    },
    "Computer": "Workstation"
  }

我尝试过 Logstashjson and split，但我无法让它发挥作用。

您可以使用额外的功能来实现您的期望ruby过滤以从子结构中提取字段：

filter {
  split {
   field => "events"
  }
  ruby {
    code => "
       event.to_hash.update(event['events'].to_hash) 
       event.to_hash.delete_if {|k, v| k == 'events'}     
    "
  }
}

结果事件将如下所示：

{
           "@version" => "1",
         "@timestamp" => "2017-01-20T04:51:39.223Z",
               "host" => "iMac.local",
          "Timestamp" => "2016-11-03T00:09:12.4905685+01:00",
              "Level" => "Debug",
    "MessageTemplate" => "Logging {@Heartbeat} from {Computer}",
    "RenderedMessage" => "Logging { UserName: \"Mike\", UserDomainName: \"Home\" } from \"Workstation\"",
         "Properties" => {
        "Heartbeat" => {
                  "UserName" => "Mike",
            "UserDomainName" => "Home"
        },
         "Computer" => "Workstation"
    }
}
