Is there a query log?

Hi, exists a log document where we can see all the queries my bucket has been receiving? I need to know if my bucket received a delete query for specific documents

thanks

SELECT * FROM system:completed_requests ;
Will return all the queries that taken more than 500ms (it is configurable) since last time query engine started.
