             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.
