TDMQ for MQTT supports daily monitoring of resource status under your account. You can view monitoring data of various MQTT resources in real time through the console to learn about the health of clusters.

View the Cluster Monitoring

1. Log in to the MQTT Console.
2. Click Monitor in the left sidebar and select the region and cluster.
3. Select the Cluster tab, set the time range, and view the cluster monitoring data.
For detailed metric introduction, refer to Monitoring Metric Description.

Viewing Topic Monitoring

TDMQ for MQTT supports automatic creation of Topics. Users do not need to pre-create related Topics when sending or receiving messages. Additionally, to facilitate Topic management, TDMQ for MQTT allows viewing monitoring metrics for specified Topic aggregations. For example, if a user uses Topic "AAA" during message transmission, it maintains a first-level Topic aggregation, making "AAA" a Topic prefix. Users can then view monitoring data for all related subtopics under this prefix, such as "AAA/1", "AAA/2", and "AAA/BBB/CCC". This enables real-time monitoring of business status under each Topic aggregation and timely tracking of key business metrics.
To facilitate the management and monitoring of key Topics, you can configure a certain number of "Topic prefixes" in the console, supporting up to three levels. For example, after configuring the prefix "a/b", you can view data statistics for Topics such as "a/b/1", "a/b/2", ..., "a/b/n".
A single cluster supports creating a maximum of 300 Topic prefixes.

Creating Topic Prefix

1. Log in to the MQTT Console.
2. Click Cluster in the left sidebar. After selecting a region, click the "ID" of the target cluster to enter the cluster basic information page.

3. Select Monitoring > Topic Prefix tab, click Create in the upper left corner, and enter the topic prefix and description in the pop-up window.
