Add the Usage page with Summary / Tokens / GPU Instances / Storage / Resource
Events tabs over the new metering endpoints: per-resource breakdowns with
date / scope / user / resource filters, trend charts, server-side sortable
tables (GPU-Hours, Instance-Hours, GB-Days, GB-Hours), Excel export with an
in-dialog preview, and KPI cards with help tooltips explaining each metric.
MaaS-only users (no Kubernetes cluster and no resource events) get a
tokens-only view with the tab bar dropped; GPU Service / the full page unlock
for admins, cluster owners, or anyone who has run a resource. Instance-type
rows reuse the GPU Instances list styling, and deleted users / instances /
volumes are flagged in breakdowns and filters.
Replace the raw flavor slug in the GPU Instances list with the product name
("<product> x <count>") plus an info-icon popover that breaks the spec down by
category (GPU / CPU / Memory / Disk): per-card VRAM, whole-instance CPU/RAM,
system / ephemeral / persistent disks (persistent size resolved from the
referenced PV). Extract the cell into a shared InstanceTypeCell and centralize
memory formatting in formatMemoryDisplay so the GPU Instances list and the
Usage tab render identical sizes.
`${values.spec?.resources?.cpu}` turned an unset cpu into the literal
string "undefined", which fails k8s quantity validation. Omit cpu when
it has no value instead.
- bar-chart: barMinWidth so hour-granularity bars stay visible with gaps.
- pie-chart: single legend-beside-pie layout, value (percent%) tooltip,
2-decimal rounding for the Summary donut.
The data layer the resource tabs build on:
- apis/resource.ts: adapter over the unified metered_usage read API
(resource/gpu-instances/storage/summary/events breakdowns), flattening
the server's generic shape into the per-tab item shape.
- hooks/use-resource-meta.ts: loads creators/instances/volumes filter
options for the current scope.
- utils/time-buckets.ts: day/week/month/hour bucket keys + range fill.
- utils/export-breakdown.ts: derive Excel columns from antd table specs.
