how to create an outstanding patch per machine report for Satellite 6

Does anyone know how to create a report for Satellite 6 the will display the same type of information that is displayed when I go out the REDHAT and look at my classic registration list. It lists how many Errata and how may packages need to be applied to the registered host. We find this info useful for planning and checking on our patch needs. Is there any help out there with this as the books are not a real big help.
