Abstract
Computer networks are provided with a resource efficient ability to generate link performance statistics. Two counters accumulates the number of I/O operations processed by a link and the time required by the link to complete each I/O operation. The average link utilization per I/O operation may then be calculated. The number of operations per second for a link may be computed by dividing the output from the first counter by a predetermined period of time and the average number of operations using the link may be computed by dividing the output from the second counter by the predetermined period of time. An optional third counter may be employed to accumulate the number of bytes transferred by a link during each I/O operation and used to compute the average size of an I/O operation. The generated statistics are useful for such activities as problem resolution, load balancing and capacity planning.
