# Adding Subscriptions

A topic is a channel used by SMN to broadcast messages. Therefore, after you create a topic, add subscriptions. In this way, when the metric triggers an alarm, Cloud Eye sends the alarm information to subscription endpoints of the topic.

#### Adding Subscriptions

1. Log in to the management console.
2. In the upper left corner, select a region and project.
3. Under Application, select Simple Message Notification.

   The SMN console is displayed.

4. In the navigation pane on the left, choose Topics.

   The Topics page is displayed.

5. Locate the topic you want to add subscriptions to, click More under Operation, and select Add Subscription.

   The Add Subscription dialog box is displayed.

6. Specify the subscription protocol and endpoints.

   If you enter multiple endpoints, enter each endpoint on a separate line.

7. Click OK.

   The subscription you added is displayed in the subscription list.

   After the subscription is added, the corresponding subscription endpoint will receive a subscription notification. You need to confirm the subscription so that the endpoint can receive alarm notifications.
