Monitoring

GAGOS provides Kubernetes cluster monitoring dashboards.

Cluster Overview

Node Resources

View resource usage across all nodes:

• CPU - Usage vs allocatable
• Memory - Usage vs allocatable
• Pods - Running vs capacity

Pod Resources

View pod resource consumption:

• CPU requests and limits
• Memory requests and limits
• Current usage (requires metrics-server)

Resource Quotas

Monitor namespace resource quotas:

• CPU limits/requests
• Memory limits/requests
• Pod count
• PVC count
• Service count

Visual indicators show when approaching limits.

HPA Status

View Horizontal Pod Autoscaler status:

• Current replicas vs desired
• Min/Max replica settings
• Current metrics vs target
• Scale events

Requirements

Metrics Server

For real-time resource metrics, metrics-server must be installed:

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml

RBAC

GAGOS needs permissions to read:

• nodes
• pods
• resourcequotas
• horizontalpodautoscalers
• pods/metrics (from metrics.k8s.io)
