Pub/Sub audit logging

This document describes audit logging for Pub/Sub. 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

Pub/Sub does not currently write Data Access audit logs for message operations, such as Publish, Subscribe, and Acknowledge.

Service name

Pub/Sub audit logs use the service name pubsub.googleapis.com . Filter for this service:

  
 protoPayload 
 . 
 serviceName 
 = 
 "pubsub.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, Pub/Sub 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 Pub/Sub.

System events

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

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

• google.pubsub.v1.Publisher.Publish
• google.pubsub.v1.Subscriber.Acknowledge
• google.pubsub.v1.Subscriber.ModifyAckDeadline
• google.pubsub.v1.Subscriber.Pull
• google.pubsub.v1.Subscriber.StreamingPull
• tech.pubsub.PublisherService.CreateTopic
• tech.pubsub.PublisherService.DeleteTopic
• tech.pubsub.PublisherService.GetTopic
• tech.pubsub.PublisherService.ListTopics
• tech.pubsub.PublisherService.Publish
• tech.pubsub.PublisherService.PublishBatch
• tech.pubsub.SubscriberService.Acknowledge
• tech.pubsub.SubscriberService.CreateSubscription
• tech.pubsub.SubscriberService.DeleteSubscription
• tech.pubsub.SubscriberService.GetSubscription
• tech.pubsub.SubscriberService.ListSubscriptions
• tech.pubsub.SubscriberService.ModifyAckDeadline
