What Radar Shows
Topology: Full provisioning chain - NodePool → NodeClaim → Node → Pod. See which NodePool owns which NodeClaims, which Nodes they provisioned, and what Pods are running on them. NodePool → NodeClass edges show the provider-specific configuration each pool uses.
- Status conditions (Ready)
- Clickable NodeClass reference (EC2NodeClass, AKSNodeClass, or generic)
- Resource limits (CPU, memory)
- Disruption policy and consolidation settings
- Instance requirements (types, zones, architectures)
- Template labels applied to provisioned nodes
- Provisioning timeline with timestamps
- Status conditions (Initialized, Launched, Registered, Ready)
- Instance type, capacity, and zone
- Requirements (instance types, architectures, OS)
- Clickable Node and NodeClass references
- AMI selector terms and aliases
- Block device mappings (volume type, size, encryption)
- IAM role configuration
- Subnet and security group discovery tags
- Instance metadata options (IMDS configuration)
