Patent ID: 8677191

Claim:
At a computer system, a method for identifying a computer system problem potentially indicative of a computer system failure during execution of an application, the method comprising: collecting a plurality of performance indicators from a plurality of computer systems, each computer system executing a load balanced instance of said application; analyzing said plurality of performance indicators to identify a set of monitored performance indicators for said load balanced instances of said application; for each of said plurality of computer systems, collecting values for said set of monitored performance indicators, said values collected over different periods when there is varied levels of demand for said application; for each of said monitored performance indicators, calculating a general deviation across said plurality of computer systems based on said collected values; and identifying an outlying computer system, from among said plurality of computer systems, when a value for at least one of said monitored performance indicators for said computer system varies from said calculated general deviation for said at least one of said monitored performance indicators.
