Automatic identification of execution phases in load tests

A method for automatic identification of execution phases in load test data, comprising:

• receiving load test data indicating processor utilization over a period of time;
• dividing the period of time of the load test data into a plurality of contiguous intervals of equal duration;
• for each pair of proximate intervals of the plurality of intervals, comparing a first interval of the pair of proximate intervals with a second interval of the pair of proximate intervals to determine whether processor utilization is substantially equivalent therebetween;
• and
• when it is determined that the pair of proximate intervals are not substantially equivalent, recursively performing the steps of dividing the not substantially equivalent pair of proximate intervals into subintervals and demining proximate pairs of subintervals that are not substantially equivalent until the subintervals are divided down to a desired level of granularity, and characterizing a phase boundary as a time between the proximate subintervals of the desired level of granularity,
• wherein each of the above steps is performed using a computer system.

A computer system comprising:

• a processor;
• and
• a non-transitory, tangible, program storage medium, readable by the computer system, embodying a program of instructions executable by the processor to perform method steps for automatic identification of execution phases in load test data, the method comprising:
• receiving load test data indicating processor utilization over a period of time;
• dividing the period of time of the load test data into a plurality of contiguous intervals of equal duration;
• for each pair of proximate intervals of the plurality of intervals, comparing a first interval of the pair of proximate intervals with a second interval of the pair of proximate intervals to determine whether processor utilization is substantially equivalent therebetween;
• and
• when it is determined that the pair of proximate intervals are not substantially equivalent, recursively performing the steps of dividing the not substantially equivalent pair of proximate intervals into subintervals and demining proximate pairs of subintervals that are not substantially equivalent until the subintervals are divided down to a desired level of granularity, and characterizing a phase boundary as a time between the proximate subintervals of the desired level of granularity.
