Recent Page Set Statistics workspace (z/OS systems only)

The Recent Page Set Statistics workspace is available on z/OS® systems only.

The Recent Page Set Statistics workspace shows the performance of the page sets associated with the selected queue manager or buffer pool ID. It provides statistics collected over several sampling intervals, which you can use to view trends in the data. Use it to monitor page and buffer pool usage.

The IBM® MQ Monitoring agent also provides current and historical versions of this workspace.

Predefined views

The Recent Page Set Statistics workspace includes the following predefined views:

  • Recent Page Set Statistics Detail This view shows the performance of the page sets associated with the selected queue manager or buffer pool ID. It provides statistics collected over several sampling intervals, which you can use to view trends in the data. The first row, Interval Summary, contains the average of values listen in subsequent rows. Use it to monitor the following conditions:
    • Examine the percentage of pages in use and the total number of extents to ensure that no page sets are reaching capacity.
    • Examine the number of buffers from the buffer pool that are in used. If it is common for all buffers from the pool to be in use and a page set is responsible for most activity, then performance will adversely affected. Try increasing the size of the buffer pool or assigning the page set to another buffer pool.
  • Page Set Utilization This view shows, as a bar chart, page set utilization for the page set IDs associated with the selected queue manager. It provides statistics collected over several sampling intervals, which you can use to view trends in the data.
