Please see the common properties of monitor views for an explanation of the locking graph.

• All events
  All monitor events that have been recorded. Next to the navigation buttons you see the current position and the total event count as well as the time of the currently shown event. If a time spam has been cumulated (see below), that time span as well as the number of events before and after the currently selected time span are shown.
• Events of interest
  Monitor events that involve a thread or monitor that you have marked as being of interest to you. You can mark nodes as being of interest by selecting them and choosing Mark Node Of Interest from the context menu. Multiple nodes can be selecting by holding down the Shift key. Marked nodes are painted in a different color.

  Next to the navigation buttons you see the current position and the total event count involving nodes of interest or the number of events if an event of interest is currently shown. If the current event is not an event of interest, you see the number of events of interest before and after the current event.

  Events of interest do not necessarily have to contain a node of interest. For example, if a thread that has been marked as a node of interest releases a lock, the associated event does not contain that thread node anymore, but the event is still an event of interest.

  To change your selection of nodes of interest, simply select new nodes of interest or choose Remove Mark from the context menu.

• Origin time
  For blocking and waiting relationships, the tool tip contains a hyperlink to the event where the arrow first appeared.
• Monitor history
  To analyze the duration of an event, it can be useful to show it in the monitor history view. At the bottom of the tool tip, a corresponding hyperlink is available.

When you hover with the mouse over event lines, you can see the number of associated events in the status bar. When you click on an event line, the first event associated with that event line is shown in the graph. When a new event is selected with the navigation buttons or a hyperlink in the tool tip window, the timeline is scrolled so that the selected event is visible.

You can cumulate multiple events by clicking an dragging the mouse in the time line. The selected area will be shown with a green background and all events in the selected time span will be shown together in the graph. If you have marked nodes of interest, only the events of interest in the selection will be cumulated.

In a cumulated graph, each arrow can contain multiple events of the same type. In that case, the tool tip window shows the number of events as well as the total time of all contained events. A drop-down list in the tool tip window lets you switch between the stack traces of the different events and the navigation hyperlinks in the tool tip window refer to the currently selected event.
