摘要：A computer system monitors a variety of conditions indicating levels to whichdifferent components, services and resources are being utilized, and based on theselevels, determines a measure of overall system utilization. By way of example, theconditions are CPU utilizations dispatcher queue length, number of active users, numberof users in an I/O wait queue and the paging rate. The system determines and repeatedlyupdates a data value for each of the conditions representing a respective amount ofutilization. Then, the system determines a weighted summation based on the latestupdate of the data values and a significance of each of the data values in indicatingsystem utilization. Next, the system compares the weighted summation to two or morethresholds, and determines and performs an action based on the comparison of theweighted summation to the thresholds. The system determines and performs a relativelysevere action when the weighted summation exceeds the greatest of the thresholds anda relatively moderate action when the weighted summation is less than the greatest ofthe thresholds but greater than least one other of the thresholds. Thus, the action iscommensurate with the overall utilization of the computer system.
