DIAGNOSIS OF APPLICATION SERVER PERFORMANCE PROBLEMS VIA THREAD LEVEL PATTERN ANALYSIS

摘要

Performance of server that is managing a group of servers, such as in a cloud, is analyzed by identifying patterns of threads executed in the server. A command is issued, repeatedly over a time period, to an operating system of the server to return a resource consumption value representative of the amount of computing resources consumed by one or more threads. The returned resource consumption values are stored and used to generate points on a graph which depicts the amount of computing resources consumed by the one or more threads over the time period and provide task breakdowns and latency information for each of the tasks.
