CloudMonitor provides features such as metric collection, visualization, and real-time alerting. ApsaraMQ for MQTT allows you to create alert rules by using CloudMonitor to monitor the running status of the service. This helps you detect system exceptions at the earliest opportunity and improve O&M efficiency.
Metrics
When CloudMonitor calculates the values of the messaging transactions per second (TPS), message production TPS, and message consumption TPS for an ApsaraMQ for MQTT instance, a calculation coefficient is used based on the transmission quality level of the instance. For more information, see Calculation coefficients.
Resource type | Metric | Unit | Metric name | Note |
Instance | Maximum QPS per minute on the V3 instance | count/s | MaxQpsPerInstance |
|
Average QPS per minute on the instance | count/s | AverageQpsPerInstance | When the system calculates the value of this metric, a calculation coefficient is used. | |
Outbound Internet traffic per minute on the instance | bytes/min | OutboundInternetTrafficPerInstance | None. | |
Number of connections on the instance | count | ConnectionsPerInstance | None. | |
Number of subscriptions on the instance | count | SubscriptionsPerInstance | None. | |
Topic | Average number of consumed messages per second on the topic | count | SendTpsPerTopic | When the system calculates the value of this metric, a calculation coefficient is not used. |
Average number of produced messages on the topic | count | ReceiveTpsPerTopic | When the system calculates the value of this metric, a calculation coefficient is not used. | |
Number of subscriptions on the topic | count | SubscriptionsPerTopic | None. |
