Patent ID: 8005644

Claim:
A computer implemented system for network application transaction analysis, comprising: at least one processor; a user interface; and an analysis tool stored on a non-transitory computer readable medium and executable by the at least one processor to: measure an application transaction metric, calculate a historical system average associated with the application transaction metric and a historical application average associated with the application transaction metric based on server performance logs, determine whether the application transaction metric differs from the historical system average by more than a first threshold amount during a plurality of consecutive measurements, determine whether the application transaction metric differs from the historical application average by more than a second threshold amount during the plurality of consecutive measurements in response to a determination that the application transaction metric does not differ from the historical system average by more than the first threshold amount during the plurality of consecutive measurements, and output an alarm to the user interface to enable a generation of an investigation when the application transaction metric differs from the historical application average by more than the second threshold amount during the plurality of consecutive measurements.
