Predefined views

The Buffer Pool Statistics workspace includes the following predefined views:

  • Buffer Pool Statistics The Buffer Pool Statistics view shows you the performance of the buffer pools used by the selected queue manager. Select a buffer pool from this list to view further information about its performance.
  • Buffer Pool Statistics Summary This view shows the percentage of buffers available to the queue manager when buffer usage was at its highest, the percentage of total GetPage I/O operations performed by the selected queue manager that were executed using buffers, and the percentage of GetPage I/O operations that were performed without using buffers.
  • Buffer Availability This view shows, as a bar chart, the number of buffers available for use by the selected queue manager in each buffer pool.
  • GetPage I/O This view shows, as a bar chart, the percentage of total GetPage I/O operations performed by each buffer pool used by the selected queue manager. Use this view to compare the percentages of GetPage I/O operations performed by different buffer pools used by the queue manager.
