数据来源 API

使用数据来源 API 创建、更新、删除和处理 Amazon Managed Grafana 工作区中的数据来源。

注意

要在您的亚马逊托管 Grafana 工作空间中使用 Grafana API，您必须拥有有效的服务账户令牌。您可以将其包含在 API 请求的 Authorization 字段中。

获取所有数据来源

数据来源代理调用

GET /api/datasources/proxy/:datasourceId/*

代理对实际数据来源的所有调用。

查询数据来源

POST /api/ds/query

查询具有后端实现的数据来源。大多数内置数据来源都有后端实现。

示例请求

POST /api/ds/query HTTP/1.1
Accept: application/json
Content-Type: application/json

{
   "queries":[
      {
         "refId":"A",
         "scenarioId":"csv_metric_values",
         "datasource":{
            "uid":"PD8C576611E62080A"
         },
         "format": "table",
         "maxDataPoints":1848,
         "intervalMs":200,
         "stringInput":"1,20,90,30,5,0"
      }
   ],
   "from":"now-5m",
   "to":"now"
}

JSON 正文架构：

  • from/to— 指定查询的时间范围。时间可以是以毫秒为单位的 epoch 时间戳，也可以是使用 Grafana 时间单位的相对值。例如 now-5m。

  • queries：指定一个或多个查询。必须至少包含 1 个。

  • queries.datasource.uid：指定要查询的数据来源的 UID。请求中的每个查询都必须具有唯一的 datasource。

  • queries.refId：指定查询的标识符。默认值为“A”。

  • queries.format：指定返回数据的格式。有效选项是 time_series 或 table，取决于数据来源。

  • queries.max DataPoints — 确定仪表板面板可以呈现的最大数据点数量。默认值为 100。

  • queries.intervalMs：指定以毫秒为单位的时间序列时间间隔。默认值为 1000。

此外，应在请求中添加每个数据来源的特定属性（例如 queries.stringInput，如上面的请求所示）。要更好地了解如何为特定数据来源生成查询，请在您选择的浏览器中使用开发者工具，并检查向 /api/ds/query 发出的 HTTP 请求。
