Spanner audit logging

This document describes audit logging for Spanner. 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:

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

Notes

To view the time it took to process a DATA_READ or DATA_WRITE request, refer to the Processing Duration section.

Service name

Spanner audit logs use the service name spanner.googleapis.com. Filter for this service:

    protoPayload.serviceName="spanner.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, Spanner 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.

API interface audit logs

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

System events

System Event audit logs are generated by GCP systems, not direct user action. For more information, see System Event audit logs.

Processing duration

To view the time it took to process a DATA_READ or DATA_WRITE request, refer to the processingDurationSeconds field within the metadata object of the AuditLog. processingDurationSeconds helps you monitor your request latencies.

processingDurationSeconds describes the Spanner API request latency. It is the length of time (in seconds) between when the Spanner API frontend receives the first byte of a request to when it sends the last byte of a response. The time needed to process API requests in both the Spanner backend and the API layer is the latency. However, this latency doesn't include network or Google Front End overhead between Spanner clients and servers. To visualize the high-level components involved in a Spanner API request, see Spanner end-to-end latency guide.

For example, the following is an audit log that contains processingDurationSeconds information:
