cluster-usage-history

Platform reserved (system-utils only). Requires a cluster-report parent. Clones the latest cluster snapshot to the output root and appends heatClusterUsageHistory.cpuCores and heatClusterUsageHistory.memoryGiB arrays from up to the last 60 historical cluster-report outputs (oldest to newest).

When to use it

Use after cluster-report and before heat-system-dataservice-envelope when a Next timeline needs bounded usage history without changing KPI snapshot paths on the merged root.

Limitations

• Depends on cluster-report outputs; useless without that upstream chain.
• History is capped at 60 snapshots; older reports are not included.
• For integrator-owned dashboards, prefer dashboard-v2 and custom $heat-dataservice shaping.
