Thread Usage per Item Graph

Use this graph to view the threads that use an item over time. You can view how long threads block waiting to acquire an item and how long they retain or use the item.

Along the vertical axis, each row in the graph represents an item. The item name displays in a legend to the left of the graph time line. After the item name, each row displays rectangles that represent the operations on that item.

The horizontal axis represents time. Operations are positioned along the horizontal axis according to the times at which the operations begin and end. Each operation has a label that indicates the name of the thread that performs the operation. Hovering over an operation displays a tool tip with additional information.
