Abstract
A system and method suppresses chattering events in a storage system by determining a suppression level based upon a rate of growth of log files. An event management system of the storage system calculates a histogram and a set of statistics including a mean and standard deviation associated with non-chattering events. A cutoff point is determined for the non-chattering events and is utilized for each received event to determine if the received event is a chattering event. Events determined to be a chattering event are suppressed according to a predefined suppression rate.
