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:

  1. 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 54m
  2. From 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

    info

    The output below is an excerpt of the command output to only show the health status.

    Slice Health:
    Component Statuses:
    Component: dns
    Component Health Status: Normal
    Component: slicegateway
    Component Health Status: Normal
    Component: slicerouter
    Component Health Status: Normal
    Last Updated: 2023-04-10T08:54:08Z
    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:

  1. 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 76m
  2. From 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

    info

    The output below is an excerpt of the command output to only show the health status.

    Status:
    Cluster Health:
    Cluster Health Status: Normal
    Component Statuses:
    Component: nsmgr
    Component Health Status: Normal
    Component: forwarder
    Component Health Status: Normal

    Component: spire-agent
    Component Health Status: Normal
    Component: spire-server
    Component Health Status: Normal
    Component: istiod
    Component 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 is 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.
