Cloud Bigtable API audit logging

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

• Types of audit logs
• Audit log entry structure
• Storing and routing audit logs
• Cloud Logging pricing summary
• Enable Data Access audit logs

Notes

When a log entry exceeds thesize limit, Cloud Logging splits that entry and distributes the data across several entries. To learn how to identify and reassemble split audit logs, seeSplit audit log entries.

Service name

Cloud Bigtable API audit logs use the service namebigtable.googleapis.com.Filter for this service:

protoPayload.serviceName="bigtable.googleapis.com"

Methods by permission type

Each IAM permission has atype property, whose value is an enumthat can be one of four values:ADMIN_READ,ADMIN_WRITE,DATA_READ, orDATA_WRITE. When you call a method,Cloud Bigtable API generates an audit log whose category is dependent on thetype property of the permission required to perform the method.Methods that require an IAM permission with thetype property valueofDATA_READ,DATA_WRITE, orADMIN_READ generateData Access audit logs.Methods that require an IAM permission with thetype property valueofADMIN_WRITE generateAdmin Activity audit logs.

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 Bigtable API.

Methods that don't produce audit logs

A method might not produce audit logs for one or more of the followingreasons:

• It is a high volume method involving significant log generation and storage costs.
• It has low auditing value.
• Another audit or platform log already provides method coverage.

The following methods don't produce audit logs:

• grpc.lookup.v1.RouteLookupService.RouteLookup
