Abstract:
A method for monitoring the state of a computer system, the method comprising:collecting a set of raw data points over a measurement interval L, wherein the set of raw data points relates to one or more processes on the computer system; storing the set of raw data points in a memory; sampling the memory repetitively at a sample interval &Dgr; to create a set of sampled data points, wherein processes which are included in the set of sampled data points are seen processes and processes which are not included in the set of sampled data points are unseen processes, and wherein the set of sampled data points includes a first sampling time and a last sampling time for each seen process; statistically estimating a total uncaptured utilization Uuc, wherein the total uncaptured utilization is an estimation of a total length of unsampled segments for the seen processes of the one or more processes over the measurement interval; statistically estimating a total unseen utilization Uus, wherein the total unseen utilization is an estimation of a total length of the unseen processes of the one or more processes over the measurement interval.
