CKAD — Monitoring Resource Usage

Monitoring Resource Usage

# Pod resource usage (requires metrics-server)
kubectl top pods
kubectl top pods -n dev --sort-by=memory

# Node resource usage
kubectl top nodes

# Check allocated vs capacity for a node
kubectl describe node worker-1 | grep -A10 "Allocated resources"
# Expected:
# Allocated resources:
#   Resource           Requests     Limits
#   cpu                1250m (62%)  2500m (125%)
#   memory             768Mi (52%)  1536Mi (103%)
