Method and system for auto-adjusting thresholds for efficient monitoring of system metrics
View Patent ↗Automatically setting a new threshold for a computer metric by detecting a first threshold for the computer metric, continuously taking measurements of the value of the computer metric at a predetermined rate, calculating the average of the measurements of the value of the computer metric over a predetermined time period, and calculating a second threshold for the computer metric based on the average of the values of the measurements. Calculating the second threshold may comprise establishing a base value for the threshold, establishing a maximum deviation of the threshold, and determining the average of the value of the measurements with respect to the base value and the maximum deviation.
