Historical Message Manager Performance workspace (z/OS systems only)

The Historical Message Manager Performance workspace is available on z/OS® systems only.

The Historical Message Manager Performance workspace summarizes the rates at which messages are being passed to and retrieved from your monitored z/OS queue managers.

IBM® MQ Monitoring agent also provides current and recent versions of this workspace, which you can use to view the latest available report data or a recent snapshot of data taken at a particular point in time.

Predefined views

Historical Message Manager Performance workspace includes the following predefined views:

  • Historical Message Manager Performance This view summarizes the rates at which messages are being passed to and retrieved from your monitored z/OS queue managers, over the selected period of time for which historical records are available. Most of these are measured in terms of the frequency with which certain IBM MQ (WebSphere® MQ) application programming interface (API) routines are called. From this table you can view the activity history of message managers. This table displays the frequency with which the following IBM MQ (WebSphere MQ)operations are performed:
    • queues are opened or closed (MQOPEN and MQCLOSE routines)
    • messages are put on or removed from queues (MQPUT and MQGET routines)
    • an MQPUT1 call is used to open a queue, put a message and then close the queue again in a single operation (MQPUT1 routine)
    • object attributes are queried or modified (MQINQ and MQSET routines)
    • subscriptions are registered to certain topics (MQSUB routines)
    • requests on subscriptions are made (MQSUBRQ routines)
    • callbacks are called by MQ when certain events occur (MQCB routines)
    • controlling actions are performed on the object handles opened for a connection (MQCTL routines)
    • status information are retrieved (MQSTAT routines)
    • messages are put on queues, or distribution lists, or to topics.
    • Handles are closed independently of MQI calls
  • Requests This view shows, as a bar chart, the frequency with which the following MQI methods have been called on the selected queue manager:
    • MQOPENs
    • MQCLOSEs
    • MQGETs
    • MQPUTs
    • MQPUT1s
    • MQINQs
    • MQSETs
    • MQSUBs
    • MQSUBRQs
    • MQCBs
    • MQCTLs
    • MQSTATs
    • Close handles per second
