Control access with IAM

To use Monitoring, you must have the appropriate Identity and Access Management (IAM) permissions. In general, each REST method in an API has an associated permission. To use the method, or use a console feature that relies on the method, you must have the permission to use the corresponding method. Permissions aren't granted directly to users; permissions are instead granted indirectly through roles, which group multiple permissions to make managing them easier:

• For information about access control, see Concepts related to access management.

• For information about how to grant roles to principals, see Grant access to Cloud Monitoring.

Roles for common combinations of permissions are predefined for you. However, you can also create your own combinations of permissions by creating IAM custom roles.

Best practice

We recommend that you create Google groups to manage access to Google Cloud projects:

• For more information, see Managing groups in the Google Cloud console.
• For information about setting limits on roles, see Set limits on granting roles.
• For a complete list of IAM roles and permissions, see IAM basic and predefined roles reference.

VPC Service Controls

For further control access to monitoring data, use VPC Service Controls in addition to IAM.

VPC Service Controls provides additional security for Cloud Monitoring to help mitigate the risk of data exfiltration. Using VPC Service Controls, you can add a metrics scope to a Service Perimeter that protects Cloud Monitoring resources and services from requests originating outside the perimeter.

To learn more about Service Perimeters, see the VPC Service Controls Service Perimeter configuration documentation.

For information about Monitoring's support for VPC Service Controls, including known limitations, see the Monitoring VPC Service Controls documentation.

Grant access to Cloud Monitoring

To manage IAM roles for principals you can use the Identity and Access Management page in the Google Cloud console or the Google Cloud CLI. However, Cloud Monitoring provides a simplified interface that lets you manage your Monitoring-specific roles, project-level roles, and the common roles for Cloud Logging and Cloud Trace.

Note: To grant a principal an IAM role, you must have the IAM role of Owner.

To grant principals access to Monitoring, Cloud Logging, or Cloud Trace, or to grant a project-level role, do the following:

Console

1. In the Google Cloud console, go to the  Permissions page:

   Go to Permissions

   If you use the search bar to find this page, then select the result whose subheading is Monitoring.

   The Permissions page doesn't display all principals. It only lists those principals that have a project-level role, or a role that is specific to Monitoring, Logging, or Trace.

   The options on this page let you view all principals whose roles include any Monitoring permission.

2. Click Grant access.

3. Click New principals and enter the username for the principal. You can add several principals.

4. Expand Select a role, select a value from the By product or service menu, and then select a role from the Roles menu:

   By product or service selection	Roles selection	Description
   Monitoring	Monitoring Viewer	View Monitoring data and configuration information. For example, principals with this role can view custom dashboards and alerting policies.
   Monitoring	Monitoring Editor	View Monitoring data, and create and edit configurations. For example, principals with this role can create custom dashboards and alerting policies.
   Monitoring	Monitoring Admin	Full access to Monitoring in the Google Cloud console and the Cloud Monitoring API. You can view Monitoring data, create and edit configurations, and modify the metrics scope.
   Cloud Trace	Cloud Trace User	Full access to the Trace console, read access to traces, and read-write access to sinks. For more information, see Trace roles.
   Cloud Trace	Cloud Trace Admin	Full access to the Trace console, read-write access to traces, and read-write access to sinks. For more information, see Trace roles.
   Logging	Logs Viewer	View access to logs. For more information, see Logging roles.
   Logging	Logging Admin	Full access to all features of Cloud Logging. For more information, see Logging roles.
   Project	Viewer	View access to most Google Cloud resources.
   Project	Editor	View, create, update, and delete most Google Cloud resources.
   Project	Owner	Full access to most Google Cloud resources.

5. Optional: To grant the same principals another role, click Add another role and repeat the previous step.

6. Click Save.

The previous steps describe how to grant a principal certain roles by using Monitoring pages in the Google Cloud console. For these roles, this page also supports edit and delete options:

• To remove roles for a principal, select the box next to the principal and then click Remove access.

• To edit the roles for a principal, click Edit. After you update the settings, click Save.

gcloud

Use the gcloud projects add-iam-policy-binding command to grant the monitoring.viewer or monitoring.editor role.

For example:

export PROJECT_ID="my-test-project"
export EMAIL_ADDRESS="[e-mail]"
gcloud projects add-iam-policy-binding \
      $PROJECT_ID \
      --member="user:$EMAIL_ADDRESS" \
      --role="roles/monitoring.editor"

You can confirm the granted roles using the gcloud projects get-iam-policy command:

export PROJECT_ID="my-test-project"
gcloud projects get-iam-policy $PROJECT_ID

Monitoring permissions included in Google Cloud roles

The Google Cloud roles include these permissions:

Name Title	Includes permissions
roles/viewer Viewer	The Monitoring permissions are the same as those in roles/monitoring.viewer.
roles/editor Editor	The Monitoring permissions are the same as those in roles/monitoring.editor with the exception of the stackdriver.projects.edit permission. The role roles/editor doesn't include the stackdriver.projects.edit permission. This role doesn't grant permission to modify a metrics scope. To modify a metrics scope when using the API, your role must include the permission monitoring.metricsScopes.link. To modify a metrics scope when using the Google Cloud console, your role must either include the permission monitoring.metricsScopes.link or you must have the role roles/monitoring.editor.
roles/owner Owner	The Monitoring permissions are the same as those in roles/monitoring.admin.

Custom roles

You might want to create a custom role when you want to grant a principal a more limited set of permissions than those granted with predefined roles. For example, if you set up Assured Workloads because you have data-residency or Impact Level 4 (IL4) requirements, then you shouldn't use uptime checks because there is no guarantee that uptime-check data is kept in a specific geographic location. To prevent usage of uptime checks, create a role that doesn't include any permissions with the prefix monitoring.uptimeCheckConfigs.

To create a custom role with Monitoring permissions, do the following:

• For a role granting permissions only for the Monitoring API, choose from the permissions in the Permissions and predefined roles section.

• For a role granting permissions for Monitoring in the Google Cloud console, choose from permission groups in the Monitoring roles section.

• To grant the ability to write monitoring data, include the permissions from the role roles/monitoring.metricWriter in the Permission and predefined roles section.

Note: Some permissions, including the permissions required to view and manage incidents, aren't supported in custom roles. Without these permissions, Monitoring in the Google Cloud console might not function properly.

If a Monitoring role is copied to create a custom role, then these permissions are omitted:

• stackdriver.projects.get
• stackdriver.projects.edit

The role Stackdriver Accounts Viewer (roles/stackdriver.accounts.viewer) includes the permission stackdriver.projects.get. The role Stackdriver Accounts Editor (roles/stackdriver.accounts.editor) includes the permission stackdriver.projects.edit.

For more information on custom roles, go to Understanding IAM custom roles.

Compute Engine access scopes

Access scopes are the legacy method of specifying permissions for your Compute Engine VM instances. The following access scopes apply to Monitoring:

Access scope	Permissions granted
https://www.googleapis.com/auth/monitoring.read	The same permissions as in roles/monitoring.viewer.
https://www.googleapis.com/auth/monitoring.write	The same permissions as in roles/monitoring.metricWriter.
https://www.googleapis.com/auth/monitoring	Full access to Monitoring.
https://www.googleapis.com/auth/cloud-platform	Full access to all enabled Cloud APIs.

For more details, go to Access scopes.

Best practice. It is a good practice is to give your VM instances the most powerful access scope (cloud-platform) and then use IAM roles to restrict access to specific APIs and operations. For details, go to Service account permissions.
