Current Replicas State Delay is a metric that show how much time the cluster takes to coming back at the desired state of pods replicas.
### Chaos Containers for masters and workers nodes
Select from the menu "Show Current Chaos Container for nodes" for watching which container start when you fire against a worker node (not an alien, they are pods).
Select from the menu "Set Custom Chaos Container for nodes" for use your preferred image or configuration for stressing Kubernetes nodes.
## Known problems
* It seems that KubeInvaders does not work with EKS because of problems with ServiceAccount. Work in progress!
