When you consume messages from a subscribed AMQP queue, the consumer side may go offline and message consumption may slow down due to network communication problems or untimely acknowledgements to received messages. In this case, messages are stacked and cannot be processed in real time.

IoTDA supports AMQP queue alarm configuration. You can set alarm rules to monitor AMQP queue message stacking and consumption speed. After a rule is triggered, alarm information is sent to you immediately so that you can locate and rectify faults in a timely manner. This section describes how to configure alarm rules for AMQP queues.

Procedure

Access the IoTDA service page and click Access Console. Click the target instance card.
In the navigation pane, choose Rules > Data Forwarding.
Click the AMQP Queues tab, locate the queue to configure alarms, and click View.

Specify an action rule for alarm notifications. When an alarm is triggered, the action rule notifies topic subscribers of the alarm through different channels (for example, emails or SMSs) based on the topic. For details, see Creating an Alarm Action Rule.
