Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A computer system which determines and acts upon a level of utilization of the computer system, said system comprising: means for monitoring a plurality of different types of conditions indicating utilization of the computer system, and determining a data value for each of said conditions representing a respective amount of utilization: means for determining a weighted summation based on the pluarity of data values and a significance of each of the data values in indicating system utilization; means for comparing said weighted summation to at least one threshold; and action means for determining and performing an action based on the comparison of said weighted summation to said threshold or thresholds; and wherein the comparing means compares said weighted summation to at least two different thresholds; and the action means determines and performs a first action when the weighted summation exceeds the greatest of the thresholds and a second action which is less severe than said first action when the weighted summation is less than the greatest of the thresholds but greater than at least one other of the thresholds.
Claim 2
Dependent Claim
179 words
A computer system which determines and acts upon a level of utilization of the computer system, said system comprising: means for monitoring a plurality of different types of conditions indicating utilization of the computer system, and determining a data value for each of said conditions representing a respective amount of utilization: means for determining a weighted summation based on the pluarity of data values and a significance of each of the data values in indicating system utilization; means for comparing said weighted summation to at least one threshold; and action means for determining and performing an action based on the comparison of said weighted summation to said threshold or thresholds; and wherein the comparing means compares said weighted summation to at least two different thresholds; and the action means determines and performs a first action when the weighted summation exceeds the greatest of the thresholds and a second action which is less severe than said first action when the weighted summation is less than the greatest of the thresholds but greater than at least one other of the thresholds.
Claim 3
Independent Claim
170 words
A method for determining and acting upon a level of utilization of a computer system, said method comprising the computer implemented steps of: monitoring a plurality of different types of conditions indicating utilization of the computer system; determining a data value for each of said conditions representing a respective amount of utilization; determining a weighted summation based on said plurality of data values and a significance of each of the data values in indicating system utilization; comparing said weighted summation to at least one threshold; and determining and performing an action based on the comparison of said weighted summation to said threshold or thresholds; and wherein the weighted summation is compared to at least two different thresholds; and the action is a first type when the weighted summation exceeds the greatest of the thresholds and a second type when the weighted summation is less than the greatest of the thresholds but greater than at least one other of the thresholds, said second type being less severe than said first type.
