Abstract:

Techniques for identifying a stack frame responsible for resource usage are described. For instance, techniques described herein enable a particular process and a particular stack frame and/or set of stack frames of the process that are high resource consumers to be identified. According to various implementations, resource usage of a process is observed and recorded over a period of time. A data structure is generated that characterizes the resource usage of the process over the sampling period. The data structure be evaluated to identify a stack frame that is responsible for excess resource consumption. In at least some implementations, a remedial procedure can be performed to attempt to reduce the process's resource usage.
