-------------------------------
Summary: Add unavailablePartitionCount and per-partition
Unavailable metrics (KIP-164)
Key: KAFKA-5341
URL: https://issues.apache.org/jira/browse/KAFKA-5341
Project: Kafka
Issue Type: New Feature
Reporter: Dong Lin
Assignee: Dong Lin
We currently have under replicated partitions, but we do not have a metrics for
unavailable partitions. Unavailable partitions could be most easily defined as
“The number of partitions that this broker leads for which the ISR is
insufficient to meet the minimum ISR required.” So if the RF was 3, and min ISR
is 2, then when there are 2 replicas in ISR this partition would be in the
under replicated partitions count. When there is 1 replica in ISR, this
partition would also be in the unavailable partitions count.
