## Problem
The **Capacity Planning** and **Namespaces** dashboards join
request/limit
metrics to `kube_pod_status_phase` via `* on (uid) group_left(phase)`.
Some pods (e.g. static pods like `ssh-proxy`) carry no `uid` label, so
every
such series collapses to the same empty match key and collides. The
query
backend rejects this with a 422:
> duplicate time series on the right side of `* on(uid)
group_left(phase)`
The affected panels render an error instead of data.
## Fix
Switch the join key to the always-unique `(namespace, pod)` and filter
`kube_pod_status_phase{phase="Running"} == 1` — the same pattern already
used
in `dashboards/gpu/gpu-quotas.json`. Sum results are unchanged (the old
multiply-by-0/1 is equivalent to filtering on `== 1`).
8 queries updated across two dashboards (CPU + memory, requests +
limits):
- `dashboards/main/capacity-planning.json` (6)
- `dashboards/main/namespaces.json` (2)

## Summary by CodeRabbit
* **Bug Fixes**
* Corrected Capacity Planning dashboard CPU/Memory percentages and
unrequested-resource calculations so they consider only running pods.
* Fixed the “% Requested” and “Unrequested” panels for both CPU and
Memory to use consistent running-pod filtering and metric matching.
* Updated the Namespaces dashboard CPU and Memory repeated panels so
Requests and Limits reflect only running-pod metrics.
