Abstract
Embodiments allow a user to define event scenarios that are used to analyze callstack and context data. Scenarios that are delayed are flagged and reported to the user with an aggregated callstack of CPU samples taken during the delay. An aggregation is done for samples for the main user interface thread of the process that is being monitored. A user may select other threads to see the callstack aggregation for that thread. The user can identify which methods use the most time for a particular delay from the callstack presentation. An event analysis tool allows quick exploration of the responsiveness issues by visualizing delays as they happen and allowing the user to drill down into callstack details for selected delays.
