This topic describes how to get started with the queue-based messaging model in the Simple Message Queue (formerly MNS) console.
Prerequisites

Create a queue
Log on to the SMQ console.

In the Create Queue panel, configure the following parameters and click OK.

Maximum Message Length: the maximum length of the message that is sent to the queue.
Long Polling Period: the maximum duration for which long polling requests are held after the ReceiveMessage operation is called. The value 0 indicates that long polling is disabled.
Visibility Timeout Period: the duration for which a message stays in the Inactive state after the message is received from the queue. For more information, see Message visibility.
Message Retention Period: the maximum duration for which a message exists in the queue. After the specified retention period, the message is deleted regardless of whether the message is received.
Message Delay Period: the period after which all messages sent to the queue are consumed.
Enable Logging Feature: specifies whether to enable the logging feature. If this feature is enabled, SMQ automatically pushes the operation logs of this queue to the specified Logstore. You can then view the message trace, delay, and other information from the logs. For more information, see Log management.
