Top

kubectl top pod
// Or we could use labels, for example app=ui, app=proxy etc.
kubectl top pod -l 'app in (ui, proxy, api)' -n my-namespace

Check the pods configuration

kubectl describe pod <pod-name> | grep -A5 "Limits"

Prints the five lines after the “Limits” section, for example

Limits:
  cpu:     500m
  memory:  1Gi
Requests:
  cpu:      50m
  memory:   256Mi

Resource Quotas

kubectl get resourcequotas
kubectl get resourcequotas -n my-namesapce

kubectl describe resourcequota {name from above call} -n my-namespace

CPU Throttling

kubectl exec <pod-name> -- cat /sys/fs/cgroup/cpu.stat
kubectl exec <pod-name> -- cat /sys/fs/cgroup/cpu/cpu.stat

For example

usage_usec 177631637
user_usec 89639616
system_usec 87992020
nr_periods 191754
nr_throttled 271
throttled_usec 11291159

– nr_periods – The number of scheduling periods that have occurred.
– nr_throttled – The number of times the process was throttled due to exceeding CPU limits.
