Creating a Custom Role

Role Availability Read-Only Analyst Manager

If the pre-defined roles Project: Viewer and Pub/Sub: Pub/Sub Subscriber are too broad for your use, or are otherwise unsuitable for you, you can define a new role whose access is limited according to your needs.

Warning: At minimum, your service account role must be assigned each of the IAM policies required for your sensor operations. Review the Required IAM Policies table to see which functions depend on which IAM policies.

These permissions can be granted at the organization level; however, if your organization is very large you may experience performance issues. In this case (as long as you don't need the sensor to monitor all projects), you can use either of the following approaches to avoid possible throttling:

This allows you to select which specific projects should be monitored by the sensor. This approach is not valid for any logging at the organization level, or any functionality dependent on organization level permissions will not be enabled.

To grant the service account permission to monitor a project

Important: This process must be followed for every project the GCP Sensor will be monitoring.

  1. In the Google Cloud Console, go to your project.
  2. Go to the IAM & admin tab in the navigation pane and click IAM.
  3. Click Add.
  4. Enter the name of the service account whose permissions you are editing.

Note: The name of the service account takes the form of an email address and will look like <name-of-sensor-service-account>@<name-of-project>.iam.gserviceaccount.com.

  1. In the Role field, select the appropriate role for this service account.
  2. Click Save.

Note: To grant the service account permission to monitor the entire organization, use these same steps but begin by opening the organization instead of the project.

At the organization level, the GCP Sensor needs the specific IAM policies in the following table.

Required IAM Policies at the Organization Level
IAM Policy Description Dependency
logging.logEntries.list Allows the sensor to fetch log entries from Stackdriver Google Cloud Audit Logs for Organizations

resourcemanager.organizations.get

Allows the sensor to get the details for a specific organization

Cloud Audit Logs for organizations

At the project level, the GCP Sensor needs the specific IAM policies in the following table.
