VProfiler is a profiler built to examine the predictability of a system. It can analyze a software system and attempts to determine the root causes of variance within that system. Through an abstraction termed a variance tree, VProfiler iteratively examines deeper and deeper nodes within a system's call graph. This results in VProfiler's ability to attribute variance to specific sections of a codebase, allowing engineers to determine the root cause of predictability issues within their system.
