You can view production, consumption, and consumer lag metrics for a topic if you are running Control Center in Normal mode.
If you are running Control Center in Reduced infrastructure mode, you cannot view topic metrics.
View topic production metrics¶

View topic consumption metrics¶
View throughput, failed consumer requests, percentage of messages consumed, and end-to-end latency.
View topic availability metrics¶

View consumer lag for a topic¶
View consumer lag for an individual topic in a consumer group.
You can view consumer lag for a consumer group from the Consumers menu.
Select a cluster from the navigation bar and click the Topics menu. The Topics Overview for Control Center opens.
Click the topic name link. The Topic details opens.
Click the Consumption panel.
Click the Consumer Lag tab. The consumer lag details are displayed for the topic, including:
- Total messages behind and the measured interval.
- A visualization of lag. The Maximum lag per consumer graph displays a pin point of each partition in the topic.
To view details for a particular point on the graph, click its pin. View the Consumer, Partition, Current offset, and Messages behind for that particular point.
Click Set up an alert to set up an alert for unacceptable consumer lag. For an example trigger, see Create a consumer group trigger for consumer lag.
