Namespace Analysis

The Namespace Analysis view provides detailed insights into individual namespaces within your Kubernetes cluster, helping you understand resource usage, security, and organization at the namespace level.

Overview

This analysis examines:

  • Resource Utilization: Per-namespace resource consumption
  • Workload Distribution: Applications and services within each namespace
  • Security Posture: Namespace-specific security configurations
  • Cost Allocation: Resource costs attributed to each namespace
  • Compliance Status: Policy adherence per namespace

Key Metrics

Resource Usage by Namespace

  • CPU and memory consumption
  • Storage utilization
  • Network traffic
  • Pod counts and density

Workload Analysis

  • Deployment types and versions
  • Service exposure patterns
  • ConfigMap and Secret usage
  • Persistent volume claims

Security Assessment

  • RBAC configurations
  • Network policies
  • Pod security standards
  • Service account usage

Namespace Comparison

Resource Efficiency Comparison

# Compare resource efficiency across namespaces
k8s-analyzer analyze --view namespace-analysis --compare-efficiency

# Example output format:
Namespace     CPU Usage    Memory Usage    Storage    Efficiency Score
production    75%          68%             85%        B+
staging       45%          52%             60%        C+
development   25%          30%             40%        A-

Cost Analysis

  • Per-namespace cost breakdown
  • Resource cost trends
  • Cost optimization opportunities
  • Budget allocation recommendations

Multi-Tenant Analysis

Tenant Isolation

  • Resource quotas and limits
  • Network segmentation
  • RBAC isolation effectiveness
  • Storage isolation

Fair Share Analysis

  • Resource allocation fairness
  • Usage versus allocation ratios
  • Over/under-utilized namespaces
  • Capacity planning per tenant

Usage Examples

# Analyze all namespaces
k8s-analyzer analyze --view namespace-analysis

# Focus on specific namespace
k8s-analyzer analyze --view namespace-analysis --namespace production

# Compare multiple namespaces
k8s-analyzer analyze --view namespace-analysis --namespaces prod,staging,dev

# Generate namespace report
k8s-analyzer report --template namespace-summary --namespace production

Namespace Optimization

Right-sizing Recommendations

  • Resource quota adjustments
  • Limit range optimizations
  • Pod density improvements
  • Storage allocation tuning

Security Enhancements

  • RBAC tightening suggestions
  • Network policy recommendations
  • Security context improvements
  • Secret management optimizations

Monitoring and Alerting

Key Performance Indicators

  • Resource utilization thresholds
  • Pod failure rates
  • Service availability metrics
  • Security violation counts

Automated Policies

# Example namespace policy
apiVersion: v1
kind: ResourceQuota
metadata:
  name: production-quota
  namespace: production
spec:
  hard:
    requests.cpu: "20"
    requests.memory: 40Gi
    limits.cpu: "40"
    limits.memory: 80Gi
    persistentvolumeclaims: "10"

Governance and Compliance

Policy Enforcement

  • Resource governance policies
