Creating an SMN Topic

Once you have created an SMN topic, you can easily subscribe to it by going to the Topic Management > Topics page of the SMN console. You can choose to receive notifications via SMS or email. After the subscription is successful, if a job fails, the system automatically sends a message to the subscription endpoint you specified.

• If a job fails within 1 minute of submission, a message notification is not triggered.
• If a job fails after 1 minute of submission, the system automatically sends a message to the subscriber terminal you specified.

1. On the Resources > Queue Management page, click Create SMN Topic on the upper left side. The Create SMN Topic dialog box is displayed.
2. Select a queue and click OK.
   Note

   • You can select a single queue or all queues.
   • If you create a topic for a queue and another topic for all queues, the SMN of all queues does not include the message of the single queue.
   • After a message notification topic is created, you will receive a message notification only when a Spark job created on the subscription queue fails.

3. Click Topic Management in to go to the Topic Management page of the SMN service.
4. In the Operation column of the topic, click Add Subscription. Select Protocol to determine the subscription mode.

5. After you click the link in the email, you will receive a message indicating that the subscription is successful.
6. Go to the Subscriptions page of SMN, and check that subscription status is Confirmed.
