摘要： A system and method for characterizing runtime behavior of a computer program executing in an execution environment, the method comprising: identifying one or more instances of yield points in a program to be executed, each yield point indicating a potential sampling operation during program execution; during program execution, in response to an identified yield point instance, ascertaining a state of the execution environment for indicating whether a sampling operation is to be performed; and, when the state of the execution environment indicates a sampling operation, recording relevant information for characterizing behavior of the execution environment. Relevant information for characterizing program behavior includes frequencies of methods executed in the program, and calling context associated with methods called by the program. Different mechanisms are provided for determining the sampling condition including the setting of a trigger bit by a runtime system, or, determining a sampling operations based on a fixed percentage of all executed yield points taken.

摘要： Identifying computer system markers to understand computer system performance, in one aspect, may comprise identifying a set of executions of applications indicative of computer performance based on first values associated with a first set of artifacts in the set of executions. Two subsets of executions from said identified set of executions are selected based on second values associated with a second set of artifacts in the set of executions. One or more markers are identified by determining one or more third set of artifacts from the two subsets of executions that have an associated third value that is different in a first of the two subsets from a second of the two subsets of executions according to a criterion.
