Marc,
Thanks for your post. Since we do not publish the SQL schema for Auditor, I can’t provide too much information about your question. For the first part, I would look into using the MCP add-on to create an MCP server that you can use to search the Auditor database, you may find the information you are looking for.
I can tell that you that we do not collect AccessTime, so that will not be in the database, so you won’t be able to report on that. If that is something that interest you, you can always leave an idea on the Ideas Portal.
You can find out more about the MCP server from here: Official Auditor MCP Server - Auditor / Show & Tell - Netwrix Community
