Using DBR_GR_XXX with value monitors could place a fair burden on the IOC though. Filling in a dbr_gr_double structure for instance requires the IOC to call the record type's get_units(), get_precision(), get_graphic_double() and get_alarm_double() routines, and the calling tree to get to them from the db_get_field() that rsrv calls is several levels deep in some cases.
