Access control

Google Cloud offers Cloud Identity and Access Management (Cloud IAM), which lets you give granular access to specific Google Cloud resources and prevents unwanted access to other resources. This page describes the Cloud IAM roles for Stackdriver Trace.

To learn how to assign Cloud IAM roles to a user or service account, read Managing policies in the Cloud IAM documentation.

projects.traces.get / GetTraceRequest	cloudtrace.traces.get	project
projects.patchTraces / PatchTracesRequest	cloudtrace.traces.patch	project

Console permissions

The following table lists the permissions required to use the Stackdriver Trace pages in the Cloud Console:

Activity	Required permissions
Read-only access to the Trace console.	cloudtrace.insights.get cloudtrace.insights.list cloudtrace.stats.get cloudtrace.tasks.get cloudtrace.tasks.list cloudtrace.traces.get cloudtrace.traces.list resourcemanager.projects.get resourcemanager.projects.list

Custom roles

To create a custom role that includes Stackdriver Trace permissions, do the following:

• For a role granting permissions only for the Stackdriver Trace API, choose from the permissions in the preceding section, API permissions.
• For a role granting permissions for the Stackdriver Trace API and console, choose permission groups in the preceding section, Console permissions.
• To grant the ability to write trace data, include the permission(s) in the role roles/cloudtrace.agent in the section Roles.
