A method of monitoring an element in a computer network including monitoring a preselected variable relating to that element; defining a threshold for the monitored preselected variable; establishing a sliding window in time; repeatedly generating a time above threshold value, the time above threshold value being a measure of an amount of time during which the monitored variable exceeded the threshold during the sliding window of time; detecting when the time above threshold value exceeds a condition window value; and in response to detecting when the time above threshold value exceeds the condition window, generating an alarm.

What is claimed is: 1. A method of displaying on a computer display screen historical performance of an element on a network, said method comprising:monitoring performance of the element;for each of a plurality of time slots that recur periodically over a plurality of cycles, deriving a measure of performance for the element from its monitored performance, wherein the plurality of time slots include a first time slot that recurs each cycle and a second time slot separate from the first time slot that recurs each cycle;for each of the plurality of time slots, computing an average value for the measure of performance of the element over corresponding time slots such that a first average value for the measure of performance of the element is computed for the first time slot over a plurality of cycles and a second average value for the measure of performance of the element is computed for the second time slot over a plurality of cycles;for each of the plurality of time slots, computing a measure variability for the measure of performance during the most recent occurrence of the time slots in comparison to the average value over corresponding time slots such that a first measure variability is computed from a derived measure of performance during a most recent occurrence of the first time slot and the first average value, and such that a second measure variability is computed from a derived measure of performance during a most recent occurrence of the second time slot and the second average value; andon the computer display screen: (1) displaying a first indicator of the computed average value over time slots corresponding to that time slot such that the first indicator is displayed for each of the first time slot and the second time slot and indicates the first average value and the second average value, respectively; (2) displaying a second indicator of the measure variability for the time slots such that the second indicator is displayed for each of the first time slot and the second time slot and indicates the first measure variability and the second measure variability, respectively; and (3) displaying a third indicator of the derived measure of performance for the individual time slots such that the derived measure of performance for the most recent occurrence of the first time slot is displayed and the derived measure of performance for the most recent occurrence of the second time slot is displayed.
