Resource Quotas

KubeVision visualizes namespace-level resource quotas as live progress bars, making it easy to see how close a namespace is to its limits at a glance.

What Is Displayed

For each namespace that has a ResourceQuota object, KubeVision shows:

Metric	Source Object	Unit
CPU requests	ResourceQuota	cores
CPU limits	ResourceQuota	cores
Memory requests	ResourceQuota	GiB
Memory limits	ResourceQuota	GiB
Pod count	ResourceQuota	count
Default container CPU/memory	LimitRange	displayed separately

If a namespace has no ResourceQuota, the quota panel shows "No quota configured" rather than empty bars.

Progress Bar Thresholds

The color of each progress bar changes based on utilization percentage:

Usage	Bar Color	Meaning
0 – 79 %	Green	Healthy headroom
80 – 94 %	Amber	Approaching limit
95 – 100 %	Red	Near or at limit

warning

When a namespace reaches 100% of its pod or CPU quota, new workloads will be rejected by the Kubernetes API Server with a 403 Forbidden quota exceeded error. Monitor amber namespaces proactively.

Accessing the Quota View

1. Select a cluster from the top navigation bar
2. Go to Namespaces
3. Click any namespace row to open the detail drawer
4. Select the Resource Quota tab

Alternatively, the namespace list table shows a compact inline quota bar for CPU and memory so you can spot constrained namespaces without drilling in.

API

GET /api/v1/clusters/:cluster/namespaces/:namespace/quota

Response example:

{
  "namespace": "team-alpha",
  "cluster": "prod-us",
  "quotas": [
    {
      "name": "default",
      "hard": { "cpu": "8", "memory": "16Gi", "pods": "20" },
      "used": { "cpu": "5200m", "memory": "11Gi", "pods": "14" },
      "percentages": { "cpu": 65, "memory": 68, "pods": 70 }
    }
  ],
  "limit_ranges": [
    {
      "name": "default-limits",
      "default_cpu": "500m",
      "default_memory": "256Mi"
    }
  ]
}

tip

The percentages field is pre-computed by the backend, so the frontend only needs to render the value — no math in the component.

Alerts

If a namespace exceeds the amber threshold (80%), a warning badge appears next to the namespace name in the sidebar and in the namespace list. Clicking the badge jumps directly to the quota tab.

To receive external notifications when quotas are near capacity, configure a webhook filtered to resource: ResourceQuota and event: update.
