Early Detection Of Failing Computers

摘要

A computer management system may track services on multiple computers executing the same workload. Various performance counters may be retrieved from the computers and analyzed to identify those with low deviations and low mean deviations. Statistical tests may then be used to compare the values of a particular computer to the deviation of the group of computers to identify outliers, which may indicate degraded performance and imminent failure of the computer. The management system may analyze any collectable performance related parameter to identify outlying systems.

1. At a computer system, the computer system including a processor, a method for identifying a computer system problem during execution of an application, instances of the application load balanced on a plurality of devices, the method comprising:
identifying a set of performance indicators that are to be monitored for the application; for each of the plurality of devices, the processor collecting values for the set of performance indicators, the values collected over different periods when there is varied levels of demand for the application; for each of the performance indicators, calculating an average value based on said collected values; and identifying a device as an outlying device when a value for a monitored performance indicator for the device varies from the calculated average for the monitored performance indicator, the identified device identified from among the plurality of devices.
