SAVFL clients cannot be managed by the SEPM, they can only forward logs. If you look at the SAVFL Report link I posted from Mick2009, it does show definition dates so you may want to look into setting up the SAVFL Reporter. Mick's article shows you how to do so.
A snippet from Mick's article reads:
"Using various filters, it is possible to generate a list of all the Linux machines that are configured to report in to this SEPM, view their definitions date (as illustrated, above), see when they have been scanned, what threats were found, and so on.
It's also possible to configure notifications which can be triggered by the incoming SAVFL Reporter data. So if there's an outbreak on your Linux file server, the admin's smartphone can get a "Alert!!" email from the SEPM, enabling her to grab her cape, spring into action and save the day."
I think this will get you what you need.
