Can't find BigQuery in the Audit logs

[Anya9889]

Hey everyone, 

I am trying to set up Audit logs for BigQuery (like updates to the tables), but when I to to the Audit Logs section, I can't see BigQuery as a service option to choose (can only see BigQuery Analytics Hub API, BigQuery Data Policy API, and BigQuery Migration API). 

Any ideas what this could be and how can I choose BigQuery ?

Thank you!

I believe bigquery queries are always logged, you do not need to turn on audit logging for it.

To verify this, open the log Explorer and enter in the following query:

```

protoPayload.serviceName="bigquery.googleapis.com"

severity=INFO

"SELECT"

```

Data Access audit logs are enabled by default for BigQuery, and cannot be disabled. You don't incur logging charges for BigQuery audit logs.

See Data Access audit log configuration if you're looking for a starting audit log configuration for security monitoring while limiting log volumes. That same guide has sample SQL queries to analyze BigQuery data access patterns:
