Real-time monitoring

Real-time monitoring is a technique that allows you to determine the current state of queues and channels within a queue manager. A number of commands are available that when issued return real-time information about queues and channels. Varying amounts of information can be returned for a single queue or channel, or for multiple queues or channels. The information returned is accurate at the moment the command was issued. Real-time monitoring can be used to:

• Help system administrators understand the steady state of their WebSphere MQ system. This helps with problem diagnosis if a problem occurs in the system.

• Determine the condition of your queue manager at any moment, even if no specific event or problem has been detected.

• Assist in determining the cause of a problem in your system.

When using real-time monitoring, information can be returned for either queues or channels. The amount of real-time information returned is controlled by queue manager, queue, and channel attributes. For more information see An introduction to real-time monitoring.

Real-time monitoring for queues and channels is in addition to, and separate from, performance and channel event monitoring.
