ApsaraMQ for Kafka allows you to use CloudMonitor to monitor ApsaraMQ for Kafka resources that you created in your Alibaba Cloud account in real time. For example, you can monitor the status of instances, topics, and groups. You can also configure alert rules for metrics. If a metric value exceeds the specified alert threshold, CloudMonitor notifies you by using a phone call, a text message, an email, or a DingTalk chatbot notification. This allows you to troubleshoot issues at the earliest opportunity.
Metrics
The data aggregation cycle of a metric is 1 minute. Each metric is calculated once every minute. The calculated value in bytes/s can be considered as the average value of the metric within 1 minute.
The data latency of a metric is 1 minute.
The following table describes the metrics for different resource types.
Resource type | Metric | Unit |
Instance | InstanceMessageInput | Bytes/s |
InstanceMessageOutput | Bytes/s | |
instance_disk_capacity(%) Note The instance_disk_capacity(%) metric displays the maximum disk usage of each node on the instance. | % | |
KafkaInternetTx | Bit/s | |
KafkaInternetRx | Bit/s | |
Topic | TopicMessageInput | Bytes/s |
TopicMessageOutput | Bytes/s | |
Group | MessageAccumulation | N/A |
