Abstract

Determination of an optimum batch size for aggregating data wherein, for a number of batch sizes, costs are estimated for sending batched information to persistent storage and for losing batched data. Then, the optimum batch size is selected from the number of different batch sizes based on sums of these costs.

Claims

1. A method for determining a batch size for aggregating data comprising the steps of:

estimating first costs, as a function of different sizes, for sending data to one of the following;

a storage device and a computing node;

estimating second costs, as a function of different sizes, for losing said data; and

selecting said batch size based on said estimated first and second costs,

the steps of the estimating and selecting performed by an information logger executing on one or more processors, and receiving performance data of an application process executing on one or more of the processors, wherein the performance data is aggregated based on the selected batch size.

2. The method of claim 1 in wherein estimating said first costs comprises determining a cost function.

3. The method of claim 1 in wherein estimating said second costs comprises determining a cost function.

4. The method of claim 1 in which said batch size is determined by minimizing an aggregation of at least two of said estimated costs.

5. The method of claim 4, in which said aggregation comprises a sum.

6. The method of claim 1 further comprising the step of sending an amount of data corresponding to said batch size to at least one of said storage device and said computing node.

7. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for determining a batch size for aggregating data, the method steps comprising:

estimating first costs, as a function of different sizes, for sending data to one of the following;

a storage device and a computing node;

estimating second costs, as a function of different sizes, for losing said data; and

selecting said batch size based on said estimated first and second costs,

the method performed by an information logger executing on one or more processors, and receiving performance data of an application process executing on one or more of the processors, wherein the performance data is aggregated based on the selected batch size.
