Summary: different behavior of the values of isrExpandsPerSec Key: KAFKA-8631 URL: https://issues.apache.org/jira/browse/KAFKA-8631 Project: Kafka Issue Type: Bug Components: metrics Affects Versions: 2.1.1 Reporter: Christian Tsatedem Kuete We have a Kafka-Cluster in Production Environment and Test Environment. We have a Monitoring-Solution with Metricbeat and Jolokia. The metric "'kafka.server:name=IsrExpandsPerSec,type=ReplicaManager'" has different behavior in PROD and Test Environment. *Behavior in TEST Environment:* * The value of _IsrExpandsPerSec_ is always the half of the total numder of partitions in the Cluster. For example for a Total number of *88* Partitions the _IsrExpandsPerSec_ is always *44.* * The Value of IsrExpandsPerSec is never *0* *Behavior in Production Environment:* * The value of IsrExpandsPerSec is either the double of the total numder of partitions in the Cluster or 0. For example for a Total number of *88* Partitions the _IsrExpandsPerSec_ is either *176 or 0.* * The Value of _IsrExpandsPerSec_ is *0,* when _isrShrinksPerSec is *12*._ * _The Value of_ _IsrExpandsPerSec_ _is_ *176*_*,* when_ _isrShrinksPerSec is *0*._ We expect both values to be regularly 0.
