The system-generated name by which this message point is known.

Queue Depth

The total set of messages currently queued by the publication point for the attached subscriptions.

These messages can be:

• Shared across multiple local subscriptions
• Queued for a single subscription
• Queued for transmission to one or more remote publication points

Investigate the reason for queued messages, as follows:

• Display the runtime collection of subscriptions for this publication point and identify the subscriptions with non-zero queue depths.
• Also display the Remote publication point collection panel for this messaging engine and identify any remote publication points for the same topic space as this publication point that have a non-zero current outbound message value. If these exist, ensure that the target messaging engines are started.
