If I understand Ismael's suggestion correctly, a re-definition will improve the reliability of the monitoring tools (since there won't be false alerts in case of re-assignment) without having to switch to a new metric. I think we should choose the proposal that improves the more common usage of the metric, in this case, failure monitoring rather than reassignment. > > About your question about storage in ZK, I can't think of anything > additional that we need.
