Manikumar commented on KAFKA-5855: ---------------------------------- I am able to generate some lag. By default, consumer reads from latest, if there is no previous saved offset for that group. You can produce some 10K records and try to consume from the beginning. This should show some lag. > records-lag is always zero > -------------------------- > > Key: KAFKA-5855 > URL: https://issues.apache.org/jira/browse/KAFKA-5855 > Project: Kafka > Issue Type: Bug > Components: consumer, metrics > Affects Versions: 0.10.1.0, 0.11.0.0 > Reporter: Mohsen Zainalpour > Priority: Minor > > I use Prometheus JmxExporter to export Kafka consumer metrics but the value > of records-lag is always zero. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
