Resource Utilisation

Check Resource Requests/Limits on each node

In case you need to check how much of Resource Requests/Limits are made across all the nodes in the cluster, following command is helpful:

alias util='kubectl get nodes --no-headers | awk '\''{print $1}'\'' | xargs -I {} sh -c '\''echo {} ; kubectl describe node {} | grep Allocated -A 5 | grep -ve Event -ve Allocated -ve percent -ve -- ; echo '\'''

Outputs:
