Operation Steps
1. Log in to the Cloud Log Service console, select Log Topic in the left sidebar.
2. On the Log Topic page, click the ID/name of the log topic that needs to consume using Kafka protocol to enter the log topic management page.
3. On the log topic management page, click the Consumption over Kafka tab.
4. Scroll down the page to the monitoring section, where monitoring is divided into two dimensions: Consumption topics and consumer groups.
This section introduces monitoring metrics and configuration of alarms from both dimensions.

Consumption Topic Dimension
Monitoring Metric
Consumption logs (count): number of logs
Consumption Traffic: consumption traffic of the log topic.
Note:
If you enable two consumption groups simultaneously, the consumption traffic is the sum of the two, and likewise for the consumption count.
You may select the time interval for monitoring data above the chart.
Configuration of Alarms
Note:
To use Alarm, you need to toggle on the service log switch and have read/write permissions for cls_service_log.
You can click the alarm icon in the upper right corner of the chart 
﻿
 to configure alarms for the number of entries in consumption logs. For details, see Configure Alarm Policy.
Consumer Group Dimension
Monitoring Metric
Consumer Group Granularity: Select the consumer group you want to monitor.
Consumption Delay (seconds): The overall delay time for a consumption group.
Partition Granularity: After selecting the consumer group, further select the partition.
Consumption Delay (seconds): Delay time for a single partition.
Note:
Latest log timestamp: The timestamp of the latest log reaching CLS.
Recent log timestamp: The timestamp of the latest log consumed by the client.
Configuration Alarms
You can click the alarm icon in the upper right corner of the chart 
﻿
 to configure alarms for consumption delay. For details, see Configure Alarm Policy.
Consumption Topic Dimension
Monitoring Metric
topic consume flow: The traffic of log consumption.
topic consume count: The number of log messages consumed.
topic consume throttel: Throttling may be triggered when single partition traffic exceeds 5M/S.
Note:
If you enable two consumer groups simultaneously, the consumption traffic is the sum of the two, and likewise for the number of consumed messages.
Configuration Alarms
Click the 
﻿
 button in the topic consume throttel monitoring chart to configure alarms for Topic Consumption Throttling Count. For detailed configuration information, see Create Alarm Policy.
Enter alarm policy name
Select log topic ID

Consumer Group Dimension
Monitoring Metric
Consumer Group Granularity:
Consumer Group Unconsumed Message Count: The number of log messages that the specified consumer group has not consumed.
Topic consumption rate: The consumption rate of the specified consumer group for the log topic, measured in messages per minute.
Partition Granularity: After selecting the consumer group, further select the partition.
Partition unconsumed message count: The number of log messages that remain unconsumed within the specified partition.
Partition consumption rate: The consumption rate of log messages within the specified partition, measured in messages per minute.
Configuring Alarm
Click the alarm icon in the unconsumed message group count monitoring chart 
﻿
, navigate to the observability platform webpage, where you can configure the threshold for unconsumed message count and set up alarms. For detailed configuration information, see Create Alarm Policy.
Click the alarm icon in the number of unread messages in partition monitoring chart 
﻿
, go to the observability platform webpage, where you can configure the threshold for unconsumed message count and set up alarms. For detailed configuration information, see Creating Alarm Policy.
