Hi there,
Keen on getting started with Instance Scan? Adding some configuration or doing some customization, doing some automation, etcetera. Great! What might help you a bit on this… having a nice overview of the data model involved with Instance Scan.
In this article I'll update the data model which I shared a while months ago which was based on the Rome release. This article is based on the San Diego release!
Data Model
Let's immediately look at the big picture. Here is the Instance Scan data model for the San Diego release:
When looking at the out-of-the-box Application Menu, you might think Instance Scan doesn't involve so much. Though looking at this picture, it does. And I didn't even mention everything!
San Diego release
No major changes were done on Instance Scan with the San Diego release. Even nothing is mentioned in the ServiceNow Product Documentation. I did find:
- One (1) new out-of-the-box Scan Checks
- Field "Expand" added to existing table "Scan Target" [scan_target].
Additional explanation
Additional explanation on this picture:
- I left out system generated fields like "Created", "Created by", "Updated", "Updated by", "Updates". These are mentioned with "…". "Sys ID" I did mention.
- I left out fields inherited from the extended table mentioned. These are mentioned with "...".
- The fields colored green are references to other Instance Scan tables.
- Fields colored blue are references to non-Instance Scan tables like "Application File", "Package", "Scheduled Job", "User", or are of field type Document ID and could theoretically reference any table. I left these tables out of the picture.
"I've got more tables on my instance!"
That could be right! You could have more tables (and fields) on your instance. This is due to if your instance has been upgraded from Orlando/Paris, or that you are on a fresh San Diego Patch 0 instance. For example, if you originally upgraded from a Paris instance, you would also have a table "Check Attributes".
The picture of the data model is based on San Diego Patch 0.
"What about the red marked fields in the picture?"
In red, fields (and also one table) which are not visible on any list lay-out or form layout, and are undocumented. In one case ("Scorecard")... even has a read Access Control for role "maint"! Undocumented meaning no official ServiceNow documentation, when searching for the undocumented you might find some of my other Instance Scan articles 😀.
