A system for innately monitoring a computer system. All address and data signals transferred over the system bus. Certain ones of the address signals are selected as related to the operating conditions of the computer system. A data filter selects data signals which correspond to the selected address signals and the selected address and data signals related to operating conditions of the computer system are then stored, either in a register if the selected address and data signals are composed of dynamic information requiring frequent status updates or in a first-in, first-out memory, when the selected address and data signals are composed of less dynamic information. |

DETAILED DESCRIPTION In one embodiment, the present invention is of a system for innately monitoring a computer system which comprises means for detecting data and address signals transferred along the system bus and processing means connected to the detecting means.
The processing means selects data and address signals related to events of interest for transfer to the computer processor.
In one aspect of this embodiment of the invention, the processing means includes means for selecting address signals related to events of interest and means for selecting data signals related to the events of interest.
In another embodiment, the present invention is of a system for innately monitoring a computer system which comprises means for receiving all address and data signals transferred over the system bus, and means for selecting address signals related to operating conditions of the computer system.
A data filter selects data signals which correspond to the selected address signals and the selected address and data signals related to operating conditions of the computer system are then store& In one aspect of this embodiment, the storage means is comprised of a register file for storing dynamic information requiring frequent status updates and a first-in, first-out memory for storing less dynamic information.
