TDMQ for MQTT supports continuous monitoring of resource status under your account. You can view monitoring data for various MQTT resources in real time in the console to monitor cluster health.
Viewing Cluster Monitoring
1. Log in to the MQTT Console.
2. In the left sidebar, click Monitoring Dashboard, and select the region and cluster.
3. Select the Cluster Monitoring tab, set the time range, and view the cluster monitoring data.
Viewing Topic Monitoring
TDMQ for MQTT supports automatic topic creation. You don't need to create topics in advance when messaging. Additionally, to help you manage topics, TDMQ for MQTT lets you view monitoring metrics for specified topic prefixes. For example, if you use topic "AAA" when messaging, this topic serves as a top-level prefix. You can then view monitoring data for all related sub-topics under this prefix, such as "AAA/1", "AAA/2", and "AAA/BBB/CCC". This lets you monitor business metrics for each topic prefix in real time.
To facilitate management and monitoring of key topics, you can configure topic prefixes in the console, with support for up to three levels. For example, after configuring the "a/b" prefix, you can view metrics for topics such as "a/b/1", "a/b/2", ..., "a/b/n".
Each cluster supports up to 300 topic prefixes.
Creating a Topic Prefix
1. Log in to the MQTT Console.
2. In the left sidebar, click Cluster Management. Select a region and click the target cluster ID to enter the Cluster Basic Information page.
3. Choose the Monitoring > Topic Monitoring tab. Click Create in the upper-left corner, and enter the Topic prefix and description in the pop-up window.
Parameter | Description |

4. Click Submit to complete the creation.
