Performance diagnostic for virtual machines
Abstract:
A method for a processor to provide a chart of a performance metric in a collection interval includes creating regions by dividing the collection interval into regions of increasingly smaller time intervals and determining a mean and a variance for each region based on data points in that region, sorting the regions by their variances and means, and processing the sorted regions. Processing the sorted regions includes removing any child region when its parent region has a variance that substantially represents the child region, and replacing any two neighboring or intersecting regions with a merged region comprising the two neighboring or intersecting regions when the merged region has a variance that substantially represents the two neighboring or intersecting regions. The method further includes generating the chart by visually indicating highest ranking regions by variance in the chart and displaying the chart or transmitting the chart over a computer network.
