Elastic APM 事件摄入 API
编辑

大多数用户不需要直接与事件摄入 API 交互。

事件摄入 API 是我们所说的 APM 代理用于与 APM 服务器通信的内部协议。代理通过发送事件(捕获的信息片段)的 HTTP 请求与服务器通信。事件可以是

  • 事务
  • 跨度
  • 错误
  • 指标

每个事件都作为 HTTP 请求正文中的一行发送。这被称为 换行符分隔的 JSON (NDJSON)

使用 NDJSON,代理可以打开一个 HTTP POST 请求并使用分块编码,以便在代理中记录事件后立即将事件流式传输到 APM 服务器。这使得代理可以轻松地将每个事件序列化为换行符分隔的 JSON 流。APM 服务器也将 HTTP 正文视为压缩流,因此可以独立读取和处理每个事件。

请参阅 APM 数据模型,了解有关不同类型的事件的更多信息。

端点编辑

APM 服务器公开了以下端点,用于 Elastic APM 代理数据摄入

名称 端点

APM 代理事件摄入

/intake/v2/events

RUM 事件摄入 (v2)

/intake/v2/rum/events

RUM 事件摄入 (v3)

/intake/v3/rum/events

请求编辑

向 APM 服务器 intake/v2/events 端点发送 HTTP POST 请求

http(s)://{hostname}:{port}/intake/v2/events

8.5.0 版本开始,APM 服务器支持异步处理批次。要请求异步处理,可以在 POST 请求中将 async 查询参数设置为 intake/v2/events 端点

http(s)://{hostname}:{port}/intake/v2/events?async=true

由于异步处理将一些事件处理延迟到后台,并在客户端关闭请求后发生,因此某些错误无法传回给客户端,而是由 APM 服务器记录。此外,只有当 APM 服务器能够处理传入请求时,才会安排异步处理请求;无法处理的请求将收到内部错误 503“队列已满”错误。

对于 RUM,请改为向 APM 服务器 intake/v3/rum/events 端点发送 HTTP POST 请求

http(s)://{hostname}:{port}/intake/v3/rum/events
响应编辑

成功后,服务器将返回 202 Accepted 状态代码,且没有主体。

请记住,事件的成功与失败是相互独立的。只有在所有事件都成功的情况下,服务器才会返回 202。

错误编辑

APM 服务器可能会向代理返回两种类型的错误

  • 与事件相关的错误(通常是验证错误)
  • 与事件无关的错误

APM 服务器一个接一个地处理事件。如果在处理事件时遇到错误,则遇到的错误以及导致错误的文档将添加到内部数组中。APM 服务器只会保存 5 个与事件相关的错误。如果遇到超过 5 个与事件相关的错误,则不会将其他错误返回给代理。处理完所有事件后,将发送错误响应。

某些与特定事件无关的错误可能会立即终止请求。例如:达到 IP 速率限制、元数据错误等。如果在任何时候遇到这些错误之一,它将被添加到内部数组中并立即返回。

错误响应示例可能如下所示

{
  "errors": [
    {
      "message": "<json-schema-err>", 
      "document": "<ndjson-obj>" 
    },{
      "message": "<json-schema-err>",
      "document": "<ndjson-obj>"
    },{
      "message": "<json-decoding-err>",
      "document": "<ndjson-obj>"
    },{
      "message": "too many requests" 
    },
  ],
  "accepted": 2320 
}

如果您正在开发代理,这些错误可用于调试。

事件 API 模式编辑

APM 服务器使用一系列 JSON 模式来验证对摄入 API 的请求

元数据
编辑

每个与 APM 服务器的新连接都以 metadata 节开始。这提供了有关流中其他对象的常规元数据。

APM 服务器会保留这些元数据信息,并在需要时将其应用于流中的其他对象,而不是从代理多次发送这些元数据信息。

在 Elasticsearch 中查看文档时,元数据存储在 context 下。

Kubernetes 数据编辑

APM 代理会自动读取 Kubernetes 数据并将其发送到 APM 服务器。在大多数情况下,代理能够从容器内部读取这些数据。如果不是这种情况,或者如果要覆盖这些数据,可以设置环境变量供代理读取。这些环境变量是通过 Kubernetes 下行 API 设置的。以下是将环境变量添加到 Kubernetes pod 规范的方法

         - name: KUBERNETES_NODE_NAME
            valueFrom:
              fieldRef:
                fieldPath: spec.nodeName
          - name: KUBERNETES_POD_NAME
            valueFrom:
              fieldRef:
                fieldPath: metadata.name
          - name: KUBERNETES_NAMESPACE
            valueFrom:
              fieldRef:
                fieldPath: metadata.namespace
          - name: KUBERNETES_POD_UID
            valueFrom:
              fieldRef:
                fieldPath: metadata.uid

下表将这些环境变量映射到 APM 元数据事件字段
