Consumer-lag monitoring
Monitoring consumer lag allows you to identify slow or stuck consumers that aren't keeping up with the latest data available in a topic. When necessary, you can then take remedial actions, such as scaling or rebooting those consumers. To monitor consumer lag, you can use Amazon CloudWatch or open monitoring with Prometheus.
Consumer lag metrics quantify the difference between the latest data written to
your topics and the data read by your applications. Amazon MSK provides the following
consumer-lag metrics, which you can get through Amazon CloudWatch or through open monitoring with
Prometheus:
