> Key: HELIX-444
> URL: https://issues.apache.org/jira/browse/HELIX-444
> Project: Apache Helix
> Issue Type: Improvement
> Reporter: Zhen Zhang
> Assignee: Zhen Zhang
>
> We need a way to pull the known down partition counts out of
> DifferenceWithIdealState when an instance is offline, reducing the alert
> volume to solely the down instance notification. Without metrics from helix
> indicating the number of partitions hosted on a given participant, we can't
> reason as to which "DifferenceWithIdealState" counts are supposed to be down
> and which are an actually difference caused by something other than a node
> outage.
> These should be produced on a per-participant, per-resource basis (ie.,
> helix.i001.participantstatus.cluster.host.db.partitiongauge = 64 or whatever)
