Pushing Alarm Messages

• Create a topic named cts_test on the SMN console. For details, see Creating a Topic.
• Add subscriptions to the cts_test topic to push alarm messages. For details, see Adding a Subscription.

• Alarm messages can be sent by emails, SMS messages, and HTTP/HTTPS.
• In this example, when log events trigger the specified function, the function filters operations that are performed by users not in the IP address whitelist, and pushes alarm messages to the subscribers.
