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 a plurality of unsummarized metrics comprising a plurality of metrics corresponding to individual transactions of a plurality of transactions, wherein each of the plurality of transactions executed a program in the computing system, and a summarized metric, the summarized metric being related to the program that was executed by each of the plurality of transactions, wherein the summarized metric comprises accumulated data across all of the plurality of transactions during execution of the program, wherein the unsummarized metrics in the log file comprise a number of database calls made by each of the plurality of transactions, a number of input/output (I/O) operations performed by each of the plurality of transactions, a number of output messages or lines by each of the plurality of transactions, beginning and ending time stamp information for each of the plurality of transactions, and a transaction type of each of the plurality of transactions;

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

summing the selected unsummarized metric for each of the plurality of transactions;

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

multiplying the ratio by the summarized metric to determine an amount of the summarized metric that belongs to the given transaction based on the selected unsummarized metric.

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

3. The method of claim 1, further comprising weighting the determined ratio based on based on historical numeric data collected by a monitor of the computing system.

4. The method of claim 1, wherein the summarized metric comprises central processing unit (CPU) usage by all of the plurality of transactions.

5. The method of claim 1, wherein the selected unsummarized metric comprises the number of database calls made by each of the plurality of transactions.

6. The method of claim 1, wherein the selected unsummarized metric comprises the number of input/output (I/O) operations by each of the plurality of transactions.

7. The method of claim 1, wherein the selected unsummarized metric comprises the number of output messages or lines by each of the plurality of transactions.

8. The method of claim 1, wherein the selected unsummarized metric comprises beginning and ending time stamp information for each of the plurality of transactions.

9. The method of claim 1, wherein the selected unsummarized metric comprises the transaction type of each of the plurality of transactions.

10. The method of claim 9, 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.

11. The method of claim 1, wherein selecting the unsummarized metric of the plurality of unsummarized metrics 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.
