Monitor Slice and Cluster Health
You can check the health of a slice and the worker clusters connected to it using the corresponding YAML commands.
Monitor Slice Health
To monitor a slice's health:
Get the list of worker clusters connected to a slice using the following command:
kubectl get workersliceconfig -n kubeslice-<project>
Example
kubectl get workersliceconfig -n kubeslice-avesha
Example Output
NAME AGE
water-worker-1 54m
water-worker-2 54m
water-worker-3 54mFrom the output, note down the name of a worker cluster and use it in the following command to get the slice description:
kubectl describe workersliceconfig <worker-cluster> -n kubeslice-<project>
Example
kubectl describe workersliceconfig water-worker-1 -n kubeslice-avesha
Example Output

Component Statuses:
Component: dns
Component Health Status: Normal
Component: slicegateway
Component Health Status: Normal
Component: slicerouter
Component Health Status: Normal

Slice Health Status: Normal
When all the components are in a healthy state, the corresponding status indicates that the health is Normal.
When a component's health goes bad, the corresponding status indicates the health with a Warning. To know how to trace an issue in each component, see slice and cluster health issues.
Monitor Cluster Health
To monitor a cluster's health:
Get the list of worker clusters using the following command:
kubectl get clusters -n kubeslice-<project>
Example
kubectl get clusters -n kubeslice-avesha
Example Output
NAME AGE
worker-1 76m
worker-2 75m
worker-3 76mFrom the output, note down a worker cluster that you want to monitor and use it in the following command to get the cluster description:
kubectl describe clusters <worker-cluster> -n kubeslice-<project>
Example
kubectl describe clusters worker-1 -n kubeslice-avesha
Example Output
