"Unfortunately, DB2 11.1 is not supported in BigFix and BigFix Inventory at this moment. Please refer to the below product documentation links.
BigFix Inventory:- https://help.hcltechsw.com/bigfix/9.5/inventory/Inventory/pdf/9.2.16.pdf
It might support in future releases of BigFix but currently we do not have time frame for the same.
Kindly feel free to add any queries if you have."
If I read this correcly, it is not planned for a release at the moment.
