Abstract

Profiling under UNIX is done by inserting counters into programs either before compiling, during compiling, or during assembly. A fourth type of profiling involves monitoring the execution of a program, and gathering relevant statistics during the run. This paper looks at this method and an implementation of it, and discusses its advantages and disadvantages.
