Cloud NAT audit logging

This document describes audit logging for Cloud NAT. Google Cloud services generate audit logs that record administrative and access activities within your Google Cloud resources. For more information about Cloud Audit Logs, see the following:

Service name

Cloud NAT audit logs use the service name compute.googleapis.com. Filter for this service:

    protoPayload.serviceName="compute.googleapis.com"
  

Methods by permission type

Each IAM permission has a type property, whose value is an enum that can be one of four values: ADMIN_READ, ADMIN_WRITE, DATA_READ, or DATA_WRITE. When you call a method, Cloud NAT generates an audit log whose category is dependent on the type property of the permission required to perform the method. Methods that require an IAM permission with the type property value of DATA_READ, DATA_WRITE, or ADMIN_READ generate Data Access audit logs. Methods that require an IAM permission with the type property value of ADMIN_WRITE generate Admin Activity audit logs.

Permission type	Methods
ADMIN_READ	v1.compute.routers.aggregatedList v1.compute.routers.get v1.compute.routers.getNatIpInfo v1.compute.routers.getNatMappingInfo v1.compute.routers.getRouterStatus v1.compute.routers.list v1.compute.routers.preview
ADMIN_WRITE	v1.compute.routers.delete v1.compute.routers.insert v1.compute.routers.patch v1.compute.routers.update

API interface audit logs

For information about how and which permissions are evaluated for each method, see the Identity and Access Management documentation for Cloud NAT.
