Channel Performance for Channels with XmitQ Depth workspace

Use the Channel Performance for Channels with XmitQ Depth workspace to view performance information related to the channels whose transmission queue depth is greater than 0 in the IBM® MQ (WebSphere® MQ) environment. Based on the information provided, you can make changes to improve performance, set up situations, and verify that changes made are improving performance.

A channel provides a communications link between two queue managers (running on the same or different platforms) and shields application programs from having to deal with the complexities of a network's underlying protocols. A channel consists of a transmission queue, a message channel agent (communications program), and a communications link.

Predefined views

The Channel Performance for Channels with XmitQ Depth workspace includes the following predefined views:

  • Channel Performance for Channels with XmitQ Depth This view displays a list of channels whose transmission queue depth is greater than 0. Select a channel in this view to display its individual performance statistics.

  • Channel Performance Summary This view contains a bar chart showing, by defined type, the total number of active and inactive monitored channels running on the selected queue manager.
  • Transmission Rates This view shows, as a bar chart, the average transmission rates of each of the selected monitored channels.
