Viewing Monitoring Data
마지막 업데이트 시간:2025-04-09 11:17:09
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.
Monitoring Metrics Meaning and Descriptions
The following are the descriptions of CKafka monitoring metrics. For the metrics marked with the word Recommended in the remarks, it is recommended to configure monitoring and alerting policies for them based on user feedback and statistics. Please configure monitoring and alerting policies reasonably according to the actual situation.
Monitoring Metrics | Unit | Description |
Maximum production traffic of an instance (recommended) | MB | The peak message bandwidth for the production of a single replica of an instance, excluding the bandwidth for replica production (reference for calculating the usage percentage of instance production bandwidth), take the maximum value in unit time. |
Instance production traffic | MB | Production traffic of the instance (excluding traffic generated by replicas), summed according to the selected time granularity. |
Instance Production Bandwidth Percentage | % | The percentage of instance production bandwidth in the quota, calculate the average in unit time. |
Maximum consumption traffic of the instance (recommended) | MB | The peak bandwidth of instance consumption messages. There is no concept of replica when consuming. Take the maximum value in unit time. (Reference for calculating the usage percentage of instance consumption bandwidth). |
Instance consumption traffic | MB | Instance consumption traffic (excluding traffic generated by replicas), summed according to the selected time granularity. |
Instance Consumption Bandwidth Percentage | % | The percentage of instance consumption bandwidth in the quota, calculate the average in unit time. |
Instance Production Message Count | Count | Number of messages produced by the instance, summed according to the selected time granularity. |
Number of messages consumed by the instance | Count | Number of messages consumed by the instance, summed according to the selected time granularity. |
Total number of messages written to disk by the instance | Count | Total number of messages written to disk by the instance (excluding replicas), taking the latest value in the selected time granularity. |
Cluster message request rate | Count/s | The situation of cluster instance message request rate, including production, consumption, metadata, and Offset submission, calculating the average in unit time. |
Cluster TPS details | Count/s | The change in cluster TPS, calculating the average in unit time. |
Instance disk usage | MB | The disk usage of the instance (including replicas), taking the latest value in the selected time granularity. |
Disk usage percentage (recommended) | % | The percentage of the current disk occupancy to the total disk capacity of the instance specification, calculate the average in unit time. |
Instance production throttling times | Count | Sum of instance production throttling times according to the selected time granularity. |
Instance consumption throttling times | Count | Sum of instance consumption throttling times according to the selected time granularity. |
Number of instance connections (recommended) | Count | Sum of the number of client connections to the server, summed according to the selected time granularity. |
Topic Monitoring
Monitoring Metrics | Description |
Maximum Production Traffic (MB/s) | Topic maximum production traffic (excluding replica traffic). |
Maximum Consumption Traffic (MB/s) | Topic maximum consumption traffic. |
Number of consumed messages | The actual number of consumed messages of the topic is summed according to the selected time granularity. |
Consumption Traffic (MB) | The actual consumption traffic of the topic (excluding the traffic generated by the replica) is summed according to the selected time granularity. |
Total amount of messages occupying disk (MB) (recommended) | The total amount of messages occupied by the topic on disk (excluding replicas), with the latest value taken according to the selected time granularity. |
Number of produced messages | The actual number of messages produced by the topic is summed according to the selected time granularity. |
Production Traffic (MB) | The actual production traffic of the topic (excluding the traffic generated by replicas) is summed according to the selected time granularity. |
Total number of messages written to disk (Count) | The total number of messages written to the topic (excluding replicas), with the latest value taken according to the selected time granularity. |
topic consumption throttling Count (Count/s) | Sum of Topic consumption throttling counts according to the selected time granularity. |
topic production throttling Count (Count/s) | Summed Topic production throttling counts according to the selected time granularity. |
Topic-Partition Monitoring
Monitoring Metrics | Description |
Consumed Message Count (Count) | Number of messages consumed in the Partition, which is the total number of messages in the selected time period. |
Consumption Traffic (MB) | Actual consumption traffic of the Partition (excluding traffic generated by replicas), summed according to the selected time granularity. |
Total number of messages written to disk (Count) | The total number of messages actually written to the disk in the Partition (excluding those generated by replicas), which is the latest value in the selected time granularity. |
Total amount of messages occupying disk (MB) | The total amount of messages actually occupying the disk in the Partition (excluding replicas), which is the latest value in the selected time granularity. |
Number of produced messages (Count) | The total number of messages actually produced in the Partition, summed according to the selected time granularity. |
Production Traffic (MB) | The actual production traffic of the Partition (excluding traffic generated by replicas), summed according to the selected time granularity. |
Consumer Group-Topic Monitoring
Monitoring Metrics | Description |
Topic maximum offset | The maximum offset of all partitions in the current topic. |
Topic consumption offset (distinguishing offset maximum value) | The maximum offset consumed by the consumer group in all partitions of the current topic. |
The number of unconsumed messages in the topic (items) | The total number of unconsumed messages in all partition consumer groups of the current topic. |
Topic consumption speed (items/minute) | The sum of consumption rates of all partition consumer groups of the current topic. |
Consumer Group-Partition Monitoring
Monitoring Metrics | Description |
Partition consumption speed (items/minute) | The consumption rate of the consumer group in the partition (items/minute). |
Current consumption offset | Consumer group: The current consumption offset of the partition. |
The maximum offset of the current partition | The maximum offset of the current partition. |
The number of unconsumed messages (items) (recommended) | The number of unconsumed messages in the partition by the consumer group. |
