If you want to query the total number of sent and received messages and the transactions per second (TPS) of a topic, you can use the resource statistics feature provided by ApsaraMQ for MQTT. The feature can help analyze the causes of specific events or performance fluctuations. The resource statistics feature of ApsaraMQ for MQTT allows you to specify multiple filter conditions and a custom time range for a query. You can query only the statistics of messages that are produced and consumed within the last three days.
