Gather history task runs but ComputerVulnerability table not populated

I am told that the Gather History task runs on a schedule, but I don't have access to see messages or logs.

When I query the ComputerVulnerability table it is empty. That is the correct table right?

Can anyone think of a reason why that may not be getting populated?

I will try to get access to the logs, etc. but that will take some time.

Thanks...Paul
