Abstract

A method for apportioning summarized metrics based on unsummarized metrics in a computing system includes 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. A method for apportioning summarized metrics based on unsummarized metrics in a computing system, the method comprising:

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.

2. The method of claim 1, wherein the computing system comprises an information management system (IMS).

3. The method of claim 1, 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.

4. The method of claim 3, further comprising weighting the determined ratio based on based on historical numeric data collected by a monitor of the computing system.

5. The method of claim 1, wherein the summarized metric comprises central processing unit (CPU) usage.

6. The method of claim 1, wherein the selected unsummarized metric comprises a number of database calls made by a transaction.

7. The method of claim 1, wherein the selected unsummarized metric comprises a number of input/output (I/O) operations by a transaction.

8. The method of claim 1, wherein the selected unsummarized metric comprises a number of output messages or lines by a transaction.

9. The method of claim 1, wherein the selected unsummarized metric comprises beginning and ending time stamp information for a transaction.

10. The method of claim 1, wherein the selected unsummarized metric comprises a transaction type.

11. The method of claim 10, wherein historical numeric data related to the transaction type is used to determine the amount of the summarized metric that belongs to the transaction of the plurality of transactions based on the selected unsummarized metric.

12. The method of claim 1, wherein selecting the unsummarized metric that reflects the distribution of the summarized metric among the plurality of transactions is performed based on historical numeric data collected by a monitor of the computing system.
