Ben Stopford updated KAFKA-4179:
--------------------------------
Affects Version/s: 0.10.1.0
Description:
Add two new metrics to Kafka
PartitionBytesInRate: Equivalent to BytesInPerSec, but at a partition level
(i.e. total traffic - throttled and not throttled). This is required for
estimating how long a rebalance will take to complete. B/s. See usability
section below.
SumReplicaLag: This is the sum of all replica lag values on the broker. This
metric is used to monitor progress of a rebalance and is particularly useful
for determining if the rebalance has become stuck due to an overly harsh
throttle value (as the metric will stop decreasing).
As covered in KIP-73
https://cwiki.apache.org/confluence/display/KAFKA/KIP-73+Replication+Quotas
These make it possible for an administrator to calculate how long a rebalance
will take.
