Description
The following UI elements may not be available anymore when using the Consumer Lag page within the Confluent Cloud Console (UI):
- Consumer offsets - as the Metrics API contains only the consumer lag
- Lag information for inactive consumer groups
- Lag information for consumers that use the
assign()method
Reference: Monitor Consumer Lag via the Metrics API
Additionally, the Consumer Groups UI Page that is accessed via the "Clients" menu navigation can only display up to 1,000 consumer groups for a given cluster. We are actively working on addressing this issue.
As a workaround, it is recommended to click through the "Topics" menu navigation and select the appropriate topic to browse through a potentially smaller set of consumer groups that are consuming from a given topic.
Applies To
Confluent Cloud
Cause
As part of our effort to improve the security posture and observability of the Confluent Cloud UI, the Consumer Lag UI is being adapted to use the Confluent Cloud Metrics API.
Resolution
Additional considerations are required due to some differences in the data between the Metrics API and the previous UI backend. See: Permissions required for Consumer Lag details on Confluent Cloud UI
NOTE: Consumer Lag UI details may take up to 5 minutes to update due to Metric Data Latency.
To see more consumer group details, including offsets information, use the Kafka Admin API.
