Jay Kreps commented on KAFKA-3027: ---------------------------------- The window should advance either when an update comes or when the value is read (e.g. SampledStat.measure()), is that not happening? > Kafka metrics can be stale if there is no new update > ---------------------------------------------------- > > Key: KAFKA-3027 > URL: https://issues.apache.org/jira/browse/KAFKA-3027 > Project: Kafka > Issue Type: Bug > Components: clients > Affects Versions: 0.8.2.0, 0.9.0.0 > Reporter: Jun Rao > > Currently, org.apache.kafka.common.metrics has the issue that the reported > metric value can be stale if there is no new update.
