Last updated 1 month ago

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 . Immuta audits the activity of Immuta users on Immuta data sources.

Requirements

  • Snowflake Enterprise Edition or higher

  • : Note that the users' . 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 Immuta audit logs expire after 7 days. Export the universal audit model (UAM) logs to or , and store audit logs outside of Immuta in order to retain the audit logs long-term.

Audit frequency

Immuta collects audit records once an hour by default, and the frequency can be . 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 query audit ingestion, click Load Audit Events on the Immuta audit page.
