Patent ID: 8856312

Claim:
A method for monitoring transaction based systems having a system resource monitor and a transaction performance monitor, said method comprising the steps of: periodically collecting on a time period basis, system resource metrics values using the system resource monitor and transaction performance metrics values using the transaction performance monitor, the system resource metrics pertaining to information technology resources (IT resources) consumed in operating a data processing system; detecting using the system resource monitor when the system resource metric threshold value is exceeded; detecting using the transaction performance monitor when the transaction performance metrics threshold value is exceeded; triggering, from the transaction performance monitor, the system resource monitor for additionally collecting system resource metrics values each time a transaction performance metric threshold value is exceeded outside of a time period; calculating, for a number of time periods, the mean value of each periodically collected system resource metrics values; calculating, for the same number of time periods, the mean value of each additionally collected system resource metrics values; identifying the system resource metrics for which there is a greater than specified difference between mean value obtained with additional collections of system resource metrics values and mean value obtained with collections of system resource metrics values done on period of time basis; and setting new threshold values between the two calculated mean values for the identified system resource metrics.
