本部分讨论 Amazon API Gateway API 的 AWS X-Ray 跟踪分段、子段和其他跟踪字段。
阅读本节之前,请查看《X-Ray 开发人员指南》中的以下主题中:
针对 API Gateway API 的跟踪对象示例
本节讨论您可能在 API Gateway API 跟踪中看到的一些对象。
注释
注解可在分段和子分段中出现。它们在采样规则中用作过滤表达式,以过滤跟踪。有关更多信息,请参阅配置采样规则。
下面是 annotations
对象的一个示例,其中,API 阶段由 API ID 和 API 阶段名称标识:
"annotations": { "aws:api_id": "a1b2c3d4e5", "aws:api_stage": "dev" }
有关注释的更多信息,请参阅 X-Ray 分段文档,然后依次选择 X-Ray 分段文档和注释。
AWS 资源数据
aws
对象仅存在于分段中。以下是与默认的取样规则匹配的 aws
对象的一个示例。有关采样规则的深入说明,请参阅配置采样规则。
"aws": { "xray": { "sampling_rule_name": "Default" }, "api_gateway": { "account_id": "123412341234", "rest_api_id": "a1b2c3d4e5", "stage": "dev", "request_id": "a1b2c3d4-a1b2-a1b2-a1b2-a1b2c3d4e5f6" } }
有关 aws
对象的更多信息,请参阅 X-Ray 分段文档,然后依次选择 X-Ray 分段文档和 AWS 资源数据。
了解跟踪
以下是 API Gateway 阶段的跟踪分段。有关组成跟踪分段的字段的详细说明,请参阅 X-Ray 分段文档。
