I don't know of a "real time" way of doing this out of the box, though you can view the status at the time of the last inventory scan by going into the inventory to "OS > Drivers and Services > Service"
If you wanted to watch a specific service you could add that to your column sets.
You could also use custom defs to report back on a service that is not set the way you want it, and or have it fix it.
Not exactly what you wanted, I know.
You might also be able to use Alerting
