To see the exact permissions that are\nrequired, expand the **Required permissions** section:\n\n\n#### Required permissions\n\nThe following permissions are required to carry out tasks in\nNetwork Topology:\n\n- Open a project: ` resourcemanager.projects.get`\n- View the Network Topology graphs for a project and monitored projects: ` networkmanagement.topologygraphs.read`\n- View the metrics on the Network Topology graph: ` monitoring.timeSeries.list`\n\n\nYou might also be able to get\nthese permissions\nwith [custom roles](/iam/docs/creating-custom-roles) or\nother [predefined roles](/iam/docs/roles-overview#predefined).\n\nTo view multiple projects, you need to have the `networkmanagement.topologygraphs.read`\npermission for the [scoping project](/monitoring/settings). For more\ninformation, see [View metrics for multiple Cloud projects](/monitoring/settings/multiple-projects).\n\nFor more information about using Network Topology to visualize resources from\nmultiple projects, see\n[Multiple projects](/network-intelligence-center/docs/network-topology/concepts/overview#multi-project)."]]
