Storage Counters/Ratios Diagram

The Storage Counters/Ratios diagram shows you the counters and ratios of each ObjectStore storage object (database, segment, and page) to which your application has access during tracing. The counters or ratios are shown for the selected diagram interval. You see, for example, the number of times at which a page is fetched within the diagram interval. Page fetches at other times are not shown. You can only display this diagram if you include page state information when you start formatting your application trace.

You invoke the Storage Counters/Ratios diagram from the Windows menu of any diagram by defining the counters or ratios to be displayed in the appropriate dialogs. Then OPE calculates the values, opens the Storage Counters/Ratios diagram window, and displays the diagram.
