The function detect_repeating_patterns was not very useful for workloads with alternating long and short pauses, for example virtual machines handling network requests for each other (say a web and database server). Instead, try to find a recent sleep interval that is somewhere between the median and the mode sleep time, by discarding outliers to the up side and recalculating the average and standard deviation until that is no longer required. This should do something sane with a sleep interval series like: 200 180 210 10000 30 1000 170 200 The current code would simply discard such a series, while the new code will guess a typical sleep interval just shy of 200.
