Abstract
An event monitor includes an event counter for counting one or more preselected events detected by an event counter. The events are counted for successive time periods and an indication of system stability is calculated to detect possible error conditions. The indication of system stability is calculated by taking a nonweighted or weighted sum of the total number of events counted in the current time period, the total number of events counted in all time periods monitored, and the difference between the total number of events counted in the current time period and the total number of events counted in the preceding time period. In this manner, the event monitor is able to identify possible error conditions more quickly than systems using rate thresholding so that remedial action may be initiated sooner. In a further aspect, system stability is further assessed by counting the number of time periods in which there is an indicium of stability, and is thus able to quickly identify a potential error condition that has stabilized and for which remedial action is not necessary. In further aspects, methods for event monitoring and error detection are provided.
