Given the identity of a thread of interest and time window, a longest wait period for the thread of interest within the time window is identified. The longest wait period is used as a starting node to generate a ready tree by walking backwards through the data in a system trace to construct a tree of readying events that ready threads for running on a processor. A potentially anomalous chain of events is automatically identified and highlighted in the ready tree. A visualization of the ready tree is presented to a user so that the user can explore the events in the tree and annotate the automatically generated tree to aid in problem diagnosis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Visualization tool for system tracing infrastructure events","description":"A system and method for identifying a root cause of a wait in a computer system are provided.
