[jira] [Resolved] (KAFKA-3027) Kafka metrics can be stale if there is no new update

     [ https://issues.apache.org/jira/browse/KAFKA-3027?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jun Rao resolved KAFKA-3027.
----------------------------
    Resolution: Not A Problem

[~jkreps], yes, you are right. Tried the console producer and the metrics are up to date after the producer is idle.

> Currently, org.apache.kafka.common.metrics has the issue that the reported metric value can be stale if there is no new update. For example, in the producer, if no new data is sent to the producer instance, metrics such as record rate will be stale.
