Queue Statistics workspace

The Queue Statistics workspace displays queue usage statistics for monitored queues running on the selected queue manager. Use the statistics to compare the activity and parameters of different queues in order to resolve performance problems.

The Queue Statistics workspace contains information only about local queues and about alias queues with target object configured. This workspace does not contain information related to model queues. This is because model queues are templates from which queues can be created, not physical queues about which statistics can be collected.

The IBM® MQ Monitoring agent also provides recent and historical versions of this workspace. You can view a recent snapshot of the report data or up to 24 hours of historical data for each workspace component.

Predefined views

The Queue Statistics workspace includes the following predefined views:

  • Queue Statistics This view displays queue usage statistics for monitored queues running on the selected queue manager. Each local queue is only listed once, even if there are several alias queues mapped to it. Select a queue from this list to view more information about it. Use the statistics provided to compare the activity and parameters of different queues. The following factors can adversely affect performance:
    • Lengthy logical units of work
    • A resource intensive CICS® transaction or program
    You can also delete messages from a queue by clicking Clear Queue or Purge Queue in the menu when you right-click on the selected queue. The Clear Queue option deletes messages from a queue all together using MQSC command. The Purge Queue option deletes messages from a queue using MQGET.
    Remember:
    • If a row in this table is highlighted in yellow, that means the value of its %Full attribute is greater than zero and the value of its Total Opens attribute is equal to zero.
    • If a row in this table is highlighted in red, that means the values of its %Full attribute is greater than the value of its High Depth Threshold attribute.
  • Queue Utilization for Monitored Queues This view shows, as a bar chart, the current utilization level (percentage of available space used) of each monitored queue managed by the selected queue manager.
  • Queue Statistics Summary This view shows, as a bar chart, the following statistics about the selected queue manager:
    • Number of monitored queues
    • Number of open queues
    • Number of queues with high depth
    • Number of queues get-inhibited
    • Number of queues put-inhibited
