Getting snapshots of IBM MQ using the DISPLAY commands

IBM MQ provides the MQSC facility which can give a snapshot of the performance, and resource usage using the DISPLAY commands.

We can get an idea of the current state of IBM MQ by using the DISPLAY commands and, for the CICS adapter, the CICS adapter panels.

Use DISPLAY commands

We can use the IBM MQ MQSC DISPLAY or PCF Inquire commands to obtain information about the current state of IBM MQ. They provide information about the status of the command server, process definitions, queues, the queue manager, and its associated components. These commands are:

MQSC command	PCF command
DISPLAY ARCHIVE	Inquire Archive
DISPLAY AUTHINFO	Inquire Authentication Information Object
DISPLAY CFSTATUS	Inquire CF Structure Status
DISPLAY CFSTRUCT	Inquire CF Structure
DISPLAY CHANNEL	Inquire Channel
DISPLAY CHINIT	Inquire Channel Initiator
DISPLAY CHSTATUS	Inquire Channel Status
DISPLAY CMDSERV
DISPLAY CLUSQMGR	Inquire Cluster Queue Manager
DISPLAY CONN	Inquire Connection
DISPLAY GROUP	Inquire Group
DISPLAY LOG	Inquire Log
DISPLAY PROCESS	Inquire Process
DISPLAY QMGR	Inquire Queue Manager
DISPLAY QSTATUS	Inquire Queue Status
DISPLAY QUEUE	Inquire Queue
DISPLAY SECURITY	Inquire Security
DISPLAY STGCLASS	Inquire Storage Class
DISPLAY SYSTEM	Inquire System
DISPLAY TRACE
DISPLAY USAGE	Inquire Usage

For the detailed syntax of each command, see MQSC commands or PCF commands. All of the functions of these commands (except DISPLAY CMDSERV and DISPLAY TRACE) are also available through the operations and control panels.

These commands provide a snapshot of the system only at the moment the command was processed. To examine trends in the system, we must start an IBM MQ trace and analyze the results over a period of time.
