Overview
CKafka allows you to monitor the resources created under your account, such as instances, topics, and consumer groups, so that you can keep track of the status of your resources in real time and troubleshoot possible issues to ensure stable business operations.
This document describes how to view monitoring metrics and their descriptions in the CKafka console.
Directions
- Log in to the CKafka console.
- In the instance list, click the ID/name of an instance to go to the instance details page.
- At the top of the instance details page, click Monitoring, select resource tags, and set the time range to view the monitoring data of the instance.
Note:
You can click the following tabs to view the monitoring data of instances, topics, and consumer groups.
After selecting a partition, you can view its monitoring data.

If you don't select a partition, the current monitoring data at the topic level will be displayed.

Consumer group - topic monitoring

Descriptions of metrics
The following lists the CKafka monitoring metrics and their description. Based on user feedback and statistics, we recommend you to configure monitoring and alarming policies for metrics marked with the word recommended. Configure policies properly as needed.
Monitoring Metric | Description |
---|
Instance disk usage (MB) | Instance disk usage (including replicas), which is the latest value in the selected time period. |
Disk utilization (%) (recommended) | Ratio of the currently used disk capacity to the total disk capacity of the instance. |
Number of connections (Count) (recommended) | Number of connections between clients and servers in the cluster. |
Maximum production traffic in instance (MB) (recommended) | Instance message production bandwidth peak (excluding bandwidth of replica production). |
Maximum instance consumption traffic (MB) (recommended) | Peak bandwidth when the instance consumes messages (consumption does not involve replicas). |
Instance consumption bandwidth percentage (%) | Ratio of the instance consumption bandwidth to the quota. |
Instance consumption throttling occurrences (Count) | Number of instance consumption throttling occurrences. |
Instance production bandwidth percentage (%) | Ratio of the instance production bandwidth to the quota. |
Instance production throttling occurrences (Count) | Number of instance production throttling occurrences. |
Instance message production bandwidth peak (MB) | Instance message production bandwidth peak (including bandwidth of replica production). |
Messages stored in instance (Count) | Total number of stored messages in the instance (excluding those produced by replicas), which is the latest value in the selected time period. |
Instance consumption traffic (MB) | Consumption traffic of the instance (excluding traffic generated by replicas), which is the total traffic in the selected time period. |
Messages produced in instance (Count) | Number of messages produced in the instance, which is the total number of messages in the selected time period. |
Instance production traffic (MB) | Production traffic of the instance (excluding traffic generated by replicas), which is the total traffic in the selected time period. |
Messages consumed in instance (Count) | Number of messages consumed in the instance, which is the total number of messages in the selected time period. |
Topic monitoring
Monitoring Metric | Description |
---|
Maximum production traffic (MB/s) | Maximum production traffic in topic (excluding replica traffic). |
Maximum consumption traffic (MB/s) | Maximum consumption traffic in topic. |
Number of consumed messages (Count) | Number of messages consumed in the topic, which is the total number of messages in the selected time period. |
Consumption traffic (MB) | Consumption traffic in the topic (excluding traffic generated by replicas), which is the total traffic in the selected time period. |
Total size of stored messages (MB) (recommended) | Total size of messages in the topic (excluding those produced by replicas) that actually use disk capacity, which is the latest value in the selected time period. |
Number of produced messages (Count) | Number of messages produced in the topic, which is the total number of messages in the selected time period. |
Production traffic (MB) | Production traffic in the topic (excluding traffic generated by replicas), which is the total traffic in the selected time period. |
Total number of persistent messages (Count) | Total number of stored messages in the topic (excluding those produced by replicas), which is the latest value in the selected time period. |
Topic consumption throttling occurrences (Count/sec) | Number of topic consumption throttling occurrences, which is the total number of occurrences in the selected time period. |
Topic production throttling occurrences (Count/sec) | Number of topic production throttling occurrences, which is the total number of occurrences in the selected time period. |
Topic - partition monitoring
Monitoring Metric | Description |
---|
Number of consumed messages (Count) | Number of messages consumed in the partition, which is the total number of messages in the selected time period. |
Consumption traffic (MB) | Consumption traffic in the partition (excluding traffic generated by replicas), which is the total traffic in the selected time period. |
Number of persistent messages (Count) | Total number of messages of the partition stored in disks (excluding those produced by replicas), which is the latest value in the selected time period. |
Used disk capacity (MB) | Total size of messages in the partition (excluding those produced by replicas) that actually use disk capacity, which is the latest value in the selected time granularity. |
Number of produced messages (Count) | Actual number of messages produced in the partition, which is the total number of messages in the selected time period. |
Production traffic (MB) | Production traffic in the partition (excluding traffic generated by replicas), which is the total traffic in the selected time period. |
Consumer group - topic monitoring
Monitoring Metric | Description |
---|
Maximum offset | Maximum offset in all partitions of the topic. |
Consumption offset | Maximum consumption offset of consumer groups in all partitions of the topic. |
Number of unconsumed messages (Count) | Total number of messages not consumed by the consumer group in all partitions of the topic. |
Consumption speed (Count/min) | Total number of messages consumed by consumer groups from all partitions in the topic per second. |
