Access Control

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

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

Permissions and roles

This section summarizes the permissions and roles Trace supports.

API permissions

The following table lists the permissions that the caller must have to call each method in the Stackdriver Trace API, cloudtrace.googleapis.com/v1:

Method (REST/RPC)	Required Permission(s)	For resource type
projects.traces.list / ListTracesRequest	cloudtrace.traces.list	project
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 Platform Console:

Activity	Required permissions
Minimal 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
Add ability to create Analysis reports in the console.	Minimal permissions plus: cloudtrace.tasks.create
Add ability to delete Analysis reports in the console.	Minimal permissions plus: cloudtrace.tasks.delete
Add ability to show logs in the console.	Minimal permissions plus: logging.logEntries.list
Add ability to show the App Engine service and version filter menus.	Minimal permissions plus: appengine.applications.get appengine.services.list appengine.versions.list

Roles

IAM roles include permissions and can be assigned to users, groups, and service accounts. The following roles include the listed permissions for Stackdriver Trace:

Role name	Trace permissions	Description
roles/cloudtrace.agent Cloud Trace Agent	cloudtrace.traces.patch	For service accounts. Ability to write traces by sending the data to Stackdriver Trace.
roles/cloudtrace.user Cloud Trace User	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	Full access to the Trace console and read access to traces.
roles/cloudtrace.admin Cloud Trace Admin	Permissions in roles/cloudtrace.user, plus: cloudtrace.traces.patch	Full access to the Trace console and read-write access to traces.
roles/viewer Project Viewer	cloudtrace.insights.get cloudtrace.insights.list cloudtrace.stats.get cloudtrace.tasks.get cloudtrace.tasks.list cloudtrace.traces.get cloudtrace.traces.list	Read-only access to the Trace console and traces.
roles/editor Project Editor	Permissions from roles/viewer, plus: cloudtrace.tasks.create cloudtrace.tasks.delete	Full access to the Trace console and read access to traces.
roles/owner Project Owner	Permissions from roles/editor, plus: cloudtrace.traces.patch	Full access to the Trace console and read-write access to traces.

Custom roles

To create a custom role including Trace permissions, do the following:

• For a role granting permissions only for the Trace API, choose from the permissions in the preceding section, API permissions.
• For a role granting permssions for the 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.
