pkuwm opened a new issue #539: Add instance utilization metrics URL: https://github.com/apache/helix/issues/539 We need to monitor instance utilization in purpose of understanding why rebalance is triggered and usage of the instance's resource. CapacityGauge | Gauge of the capacity for each CAPACITY key. UsageGauge | Gauge of the real time partition weight reservation for each CAPACITY key on the participant. WeightGauge | Gauge of the average partition weight for each CAPACITY keys.Note that per-partition weight metrics would be more accurate. But the number of metrics would be too large to support.
