Hello,
using the JmxTool I discovered that one can have _no_ under replicated
partitions, but have an under minISR partition count > 0. Does anyone
know, how that can be? I was expecting that when a partition is below
the minimum in sync replica count, it would be defined as under
replicated as well.
This is how I was checking it:
[appuser@kafka-0 ~]$
jmx_metric="kafka.server:type=ReplicaManager,name=UnderReplicatedPartitions"
[appuser@kafka-0 ~]$ /bin/kafka-run-class kafka.tools.JmxTool
--object-name $jmx_metric --one-time true --jmx-url
"service:jmx:rmi:///jndi/rmi://:5555/jmxrmi"
Trying to connect to JMX url: service:jmx:rmi:///jndi/rmi://:5555/jmxrmi.
"time","kafka.server:type=ReplicaManager,name=UnderReplicatedPartitions:Value"
1715928561345,0
[appuser@kafka-0 ~]$
[appuser@kafka-0 ~]$
jmx_metric="kafka.server:type=ReplicaManager,name=UnderMinIsrPartitionCount"
[appuser@kafka-0 ~]$ /bin/kafka-run-class kafka.tools.JmxTool
--object-name $jmx_metric --one-time true --jmx-url
