Abstract
A computer system monitors a variety of conditions indicating levels to which different components, services and resources are being utilized, and based on these levels, determines a measure of overall system utilization. By way of example, the conditions are CPU utilizations dispatcher queue length, number of active users, number of users in an I/O wait queue and the paging rate. The system determines and repeatedly updates a data value for each of the conditions representing a respective amount of utilization. Then, the system determines a weighted summation based on the latest update of the data values and a significance of each of the data values in indicating system utilization. Next, the system compares the weighted summation to two or more thresholds, and determines and performs an action based on the comparison of the weighted summation to the thresholds. The system determines and performs a relatively severe action when the weighted summation exceeds the greatest of the thresholds and a relatively moderate action when the weighted summation is less than the greatest of the thresholds but greater than least one other of the thresholds. Thus, the action is commensurate with the overall utilization of the computer system.
