Patent ID: 7469366

Claim:
A method of measuring health of a high-speed interface link in a computer system, the method comprising: reading counter data representing a number of units of data sent and a number of errors for a high-speed interface link between a bus interface unit and a slave processor, wherein the counter data includes: a number (L) of packets sent to the slave processor by the bus interface unit that are lost or received with errors; a number (E) of packets received by the bus interface unit from the slave processor that contain errors; a total number (M) of packets sent from the bus interface unit to the slave processor; a total number (G) of packets received by the bus interface unit from the slave processor; and a length of time (R) the high-speed interface link spends in a recovery mode since the counter data was last read; computing a health statistic (H) based on the counter data; and displaying the health statistic H on a display device of the computer system.
