使用 IAM 控制访问权限

Google Cloud 提供 Identity and Access Management (IAM)，可让您授予对特定 Google Cloud 资源的细化访问权限，并防止对其他资源进行不必要的访问。本页面介绍了 Cloud Trace 的 IAM 角色。

• 如需了解如何向用户或服务账号分配 IAM 角色，请参阅管理对项目、文件夹和组织的访问权限。
• 如需详细了解预定义角色，请参阅 IAM：角色和权限。
• 如需有关选择最合适的预定义角色的帮助，请参阅选择预定义角色。

最佳做法

为方便排查问题，我们建议为可能需要查看项目中的轨迹数据的所有用户、群组和网域授予该项目的 Cloud Trace User 角色 (roles/cloudtrace.user)。此角色可向主要人员授予查看轨迹数据所需的权限。

权限和预定义角色

IAM 角色包含权限，可以分配给用户、组和服务账号。

Cloud Trace 角色

下表列出了 Cloud Trace 的预定义角色以及这些角色的权限：

Role	Permissions
Cloud Trace Admin (roles/cloudtrace.admin) Provides full access to the Trace console and read-write access to traces. Lowest-level resources where you can grant this role: Project	cloudtrace.* cloudtrace.insights.get cloudtrace.insights.list cloudtrace.stats.get cloudtrace.tasks.create cloudtrace.tasks.delete cloudtrace.tasks.get cloudtrace.tasks.list cloudtrace.traceScopes.create cloudtrace.traceScopes.delete cloudtrace.traceScopes.get cloudtrace.traceScopes.list cloudtrace.traceScopes.update cloudtrace.traces.get cloudtrace.traces.list cloudtrace.traces.patch observability.scopes.get observability.traceScopes.* observability.traceScopes.create observability.traceScopes.delete observability.traceScopes.get observability.traceScopes.list observability.traceScopes.update resourcemanager.projects.get resourcemanager.projects.list telemetry.traces.write
Cloud Trace User (roles/cloudtrace.user) Provides full access to the Trace console and read access to traces. Lowest-level resources where you can grant this role: Project	cloudtrace.insights.* cloudtrace.insights.get cloudtrace.insights.list cloudtrace.stats.get cloudtrace.tasks.* cloudtrace.tasks.create cloudtrace.tasks.delete cloudtrace.tasks.get cloudtrace.tasks.list cloudtrace.traceScopes.* cloudtrace.traceScopes.create cloudtrace.traceScopes.delete cloudtrace.traceScopes.get cloudtrace.traceScopes.list cloudtrace.traceScopes.update cloudtrace.traces.get cloudtrace.traces.list observability.scopes.get observability.traceScopes.* observability.traceScopes.create observability.traceScopes.delete observability.traceScopes.get observability.traceScopes.list observability.traceScopes.update resourcemanager.projects.get resourcemanager.projects.list
Cloud Trace Agent (roles/cloudtrace.agent) For service accounts. Provides ability to write traces by sending the data to Stackdriver Trace. Lowest-level resources where you can grant this role: Project	cloudtrace.traces.patch telemetry.traces.write

Telemetry API 角色

下表列出了 Telemetry (OTLP) API 的预定义角色，以及这些角色的权限：

Role	Permissions
Telemetry Admin (roles/telemetry.admin) Admin role for telemetry	resourcemanager.projects.get resourcemanager.projects.list telemetry.* telemetry.consumers.getIamPolicy telemetry.consumers.setIamPolicy telemetry.consumers.writeLogs telemetry.consumers.writeMetrics telemetry.consumers.writeTraces telemetry.traces.write

Integrated Service Telemetry Traces Writer ^Beta (roles/telemetry.serviceTracesWriter) Allows an onboarded service to write trace data to a destination.	telemetry.consumers.writeTraces
Cloud Telemetry Traces Writer (roles/telemetry.tracesWriter) Access to write trace spans.	telemetry.traces.write
Cloud Telemetry Writer (roles/telemetry.writer) Full access to write all telemetry data.	logging.logEntries.create monitoring.timeSeries.create telemetry.traces.write

创建自定义角色

如需创建包含 Cloud Trace 权限的自定义角色，请执行以下操作：

• 如需使角色仅能授予 Cloud Trace API 权限，请选择该 API 方法所需的权限。
• 如需使角色能够授予 Cloud Trace API 和控制台的权限，请从预定义的 Cloud Trace 角色中选择权限组。
• 如需授予向跟踪记录写入数据的权限，请在 Cloud Trace Agent (roles/cloudtrace.agent) 角色中添加权限。

如需详细了解自定义角色，请参阅创建和管理自定义角色。
