Identifying a trace based on wait chain coverage analysis comprises identifying a scenario covered by a plurality of traces, as well as a plurality of scenario phases. Each phase has corresponding phase beginning and ending, and is covered by corresponding trace(s) of the plurality of traces. For each prior instance of each phase, a corresponding wait chain comprising a series of wait operations is identified. After identifying signatures configured to match a subset of wait operations in wait chain(s), at least a signature coverage is calculated over the identified corresponding wait chains. The signature coverage characterizes portions(s) of these wait chains that are matched by the signature(s). Based on calculating the signature coverage, one or more of the plurality of traces are identified as having unknown wait states, based on the identified trace(s) corresponding to a larger amount of uncovered wait chain portions than others of the plurality of traces.

Two different process management views can be displayed, and a user can request to switch between the two views. The user can select a process in either view and have the selected process terminated. One view is a simplified view that identifies processes and whether they are non-responsive. The other view is an expanded view that identifies processes and the amount of various system resources used by each of those processes. Various additional information can be displayed in the expanded view, such as identifiers of various windows, tabs, and/or services associated with each of the processes.
