ABSTRACT:
A system and a method to monitor performance and resource utilization for a bus bridge in a computer system are described. All pertinent performance information for the bus bridge is stored in a statistics keeping or monitor object. A bus object is created for each bus in the system. Each bus cycle object receives the current cycle count and sends elapsed time information to the monitor object. A plurality of cycle list objects can also be used to track resource usage by sending messages to the monitor object indicating the type of cycles that enter the bus bridge. The monitor object then tracks the number of pending cycles that accumulate within the bus bridge. Thus, the statistics keeping object can indicate the current usage of each tracked resource.
