Viewing messages for object queues

View messages for object queues to gain insight into the health of your application's object queue traffic and to pinpoint the source of errors.

The Messages tab on the Object Queues page displays all undelivered messages for a selected object queue.

The Messages tab is divided into the messages list at the top and the Detail area at the bottom. The tab displays the following information:

Delivery Time

The date and time the message is scheduled to be delivered.

Error Count

The number of errors associated with the message.

Is Processing

Indicates whether the message is still processing.

Last Priority
