Abstract

A computer program product includes a computer readable storage medium containing computer code that, when executed by a computer, implements a method including receiving, by a memory device of the computing system, a log file, the log file comprising unsummarized metrics, the unsummarized metrics being related to a plurality of transactions performed by a program in the computing system, and a summarized metric, the summarized metric being related to the program, wherein the summarized metric comprises accumulated data from the plurality of transactions; selecting an unsummarized metric that reflects a distribution of the summarized metric among the plurality of transactions by a processing device of the computing system; and determining an amount of the summarized metric that belongs to a transaction of the plurality of transactions based on the selected unsummarized metric by the processing device of the computing system.

Claims

1-12. -12. (canceled)

13. A computer program product comprising a computer readable storage medium containing computer code that, when executed by a computer, implements a method for apportioning summarized metrics based on unsummarized metrics, wherein the method comprises:

receiving a log file, the log file comprising unsummarized metrics, the unsummarized metrics being related to a plurality of transactions performed by a program in the computing system, and a summarized metric, the summarized metric being related to the program, wherein the summarized metric comprises accumulated data from the plurality of transactions;

selecting an unsummarized metric that reflects a distribution of the summarized metric among the plurality of transactions; and

determining an amount of the summarized metric that belongs to a transaction of the plurality of transactions based on the selected unsummarized metric.

14. The computer program product according to claim 13, wherein determining an amount of the summarized metric that belongs to the transaction of the plurality of transactions based on the selected unsummarized metric comprises:

determining a ratio of the selected unsummarized metric for the transaction to a summation of the selected unsummarized metric for each of the plurality of transactions; and

multiplying the ratio by the summarized metric.

15. The computer program product according to claim 13, wherein the summarized metric comprises central processing unit (CPU) usage.

16. The computer program product according to claim 13, wherein the selected unsummarized metric comprises a number of database calls made by a transaction.

17. The computer program product according to claim 13, wherein the selected unsummarized metric comprises a number of input/output (I/O) operations by a transaction.

18. The computer program product according to claim 13, wherein the selected unsummarized metric comprises a number of output messages or lines by a transaction.

19. The computer program product according to claim 13, wherein the selected unsummarized metric comprises a transaction type.

20. A computing system for apportioning summarized metrics based on unsummarized metrics, the computing system comprising:

a memory device configured to receive a log file, the log file comprising unsummarized metrics, the unsummarized metrics being related to a plurality of transactions performed by a program in the computing system, and a summarized metric, the summarized metric being related to the program, wherein the summarized metric comprises accumulated data from the plurality of transactions; and

a processing device configured to;

select an unsummarized metric that reflects a distribution of the summarized metric among the plurality of transactions by a processing device of the computing system; and

determine an amount of the summarized metric that belongs to a transaction of the plurality of transactions based on the selected unsummarized metric by the processing device of the computing system.
