Cloud Bigtable API audit logging

This document describes audit logging for Cloud Bigtable API. 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:

Notes

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

Service name

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

    protoPayload.serviceName="bigtable.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 Bigtable API 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 google.bigtable.v2.Bigtable.PingAndWarm
DATA_READ google.bigtable.v2.Bigtable.ExecuteQuery
google.bigtable.v2.Bigtable.GenerateInitialChangeStreamPartitions
google.bigtable.v2.Bigtable.ReadChangeStream
google.bigtable.v2.Bigtable.ReadModifyWriteRow
google.bigtable.v2.Bigtable.ReadRows

Methods that don't produce audit logs

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

  • It is a high volume method involving signifcant 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
