Audit logging information

This document describes audit logging for Firestore with MongoDB compatibility. 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

When configuring audit logging, use the service name datastore.googleapis.com to configure both datastore.googleapis.com and firestore.googleapis.com.Once configured, logs for the Firestore with MongoDB compatibility API include the service name firestore.googleapis.com.

To view the time it took to process a DATA_READ or DATA_WRITE request, see the processing_duration field within the metadata object of an AuditLog. processing_duration describes the time the database took to process a request. This is smaller than the end-user latency. In particular, it does not include network overhead.

Service name

Firestore audit logs use the service name firestore.googleapis.com. Filter for this service:

    protoPayload.serviceName="firestore.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, Firestore 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.

Identify request callers

Audit Log entries include information about the identity that performed the logged operation. To identify a request caller, see the following fields within an AuditLog object:

• The caller's identity is held in the AuthenticationInfo field. This can include the principalEmail of the user. This information is sometimes redacted.

• The callerIp field within the requestMetadata object of an AuditLog entry includes the IP address of the caller.
