Appendix C A Technical Discussion of HP SPT/XL Data Collection
Introduction
HP SPT/XL groups the resources consumed by an application into two
categories. The first category contains resources consumed directly by
Application Code. The second contains resources consumed by System Code,
more specifically, intrinsics on behalf of the application.
Different information is needed about these two categories of resource
consumption. For example, an application programmer need not be
interested in nor aware of internal system procedures executed within an
intrinsic called by his application program. On the other hand, this is
very important where the application program is executing within its own
code. Therefore, HP SPT/XL uses two different data collection techniques
to provide the application programmer information on the two categories
of resource consumption.
