Snowflake Query Audit Logs
Snowflake query audit logs is a feature that audits queries that users run natively in Snowflake and presents them in a universal format as Immuta audit logs. Immuta uses the Snowflake QUERY_HISTORY and ACCESS_HISTORY tables and translates them into the audit logs that can be viewed at query events in the Immuta UI or exported to S3. Immuta audits the activity of Immuta users on Immuta data sources.
Requirements
Snowflake Enterprise Edition or higher
Snowflake users registered as Immuta users: Note that the users' Snowflake usernames must be mapped to Immuta. Without this, Immuta will not know the users are Immuta users and will not collect audit events for their data access activity.
Store audit logs
By default Snowflake audit logs expire after 90 days. Export the universal audit model (UAM) logs to S3 or ADLS Gen2, and store audit logs outside of Immuta in order to retain the audit logs long-term.
Audit frequency
Immuta collects audit records at the frequency configured when enabling the integration, which is between 1 and 24 hours. The frequency is a global setting based on integration type, so organizations with multiple Snowflake integrations will have the same audit frequency for all of them. The more frequent the audit records are ingested, the more current the audit records; however, there could be performance and cost impacts from the frequent jobs.
To manually request native query audit ingestion, click Load Audit Events on the Immuta audit page.
Audit schema
Each audit message from the Immuta platform will be a one-line JSON object containing the properties listed below.
