When a workload is selected for further analysis:

  • Each record in the log is mapped to classification criteria, along with a workload ID. A set of records is obtained for each classification criteria for a specific workload, including the workload ID condition.
  • The response time characteristics of these sets of records are compared against the service level goals defined for the workload (goal service level goals), and the comparison status is indicated.
  • Existing workloads that have similar response time characteristics may be grouped into a new workload with new service level goals (or the service level goals of the current workload can be modified, if all the classifications are not meeting the service level goals).
  • Records are analyzed for further classification (by identifying clusters on an uncovered classification parameter) if the standard deviation is high for a classification, or if the CPU usage is high.
