Correlation of measurements:

ARM uses a costly and cumbersome technique to achieve correlation of measurements. The application developer must care for passing identifiers of transaction instances throughout the application. Thus, correlation of subtransactions is hardly ever used today and instrumentation of component based applications is almost impossible.

Our approach completely automates correlation of measurements. By using the information about the control flows the application is executing in, no care at all must be taken by the developers about how the measurements correlate with each other. As the correlation of subtransactions thus requires no additional effort, by far more detailed measurements can be expected.
