Slice Operator Metrics

The Slice Operator metrics provide valuable insights into the performance and health of various components within the KubeSlice environment. These metrics are categorized based on different labels associated with each component. The metrics include information such as the number of active endpoints in service imports and exports, the number of application pods in each slice per namespace, the health status of the worker cluster and its components, the health status of individual slices and their components, and counters for slice-related events. These metrics help you monitor the state of your KubeSlice deployment and make informed decisions for efficient management. The metrics are accompanied by labels that provide additional context, such as the action triggering the metric, the component or object involved, the project and cluster names, and more. By leveraging these metrics and labels, you can effectively monitor and optimize your KubeSlice infrastructure.

Sl. No	Name	Type	Labels	Description

4	kubeslice_cluster_up	Gauge	slice_project, slice_cluster	Denotes 1 if the worker cluster is healthy and denotes 0 if it is unhealthy.
5	kubeslice_cluster_component_up	Gauge	slice_project, slice_cluster, component	Denotes 1 if the worker cluster is healthy and denotes 0 if it is unhealthy.
6	kubeslice_slice_up	Gauge	slice_project, slice_cluster, slice	Denotes 1 if the slice is healthy and denotes 0 if it is unhealthy.
7	kubeslice_slice_component_up	Gauge	slice_project, slice_cluster, slice, component	Denotes 1 if the slice component is healthy and denotes 0 if it is unhealthy.

Labels

The following table describes the labels that are attached to the Slice Operator metrics.

Label	Description
action	The action which triggered the metric record.
component	The KubeSlice component to which the metric is attached to.
event	The event title to which the metric is attached to.
object_kind	The kind of the object on which the metric is recorded.
object_name	The name of the object on which the metric is recorded.
namespace	The namespace of the object for which the metric is recorded.
service	The metric is related to the service discovery (service export or import).
slice	The name of the slice which the metric is attached to. The value is NA if the metric is unrelated to any slice.
slice_cluster	The name of the cluster the metric is attached to. The value is worker-cluster for all the Worker Operator related metrics.
slice_gateway	The Slice Gateway for which the metric is recorded
slice_gateway_pod	The Slice Gateway pod for which the metric is recorded.
slice_nodeaffinity	The Node Affinity of the slice for which the metric is recorded.
slice_networkpolicy	The namespace isolation policy of the slice for which the metric is recorded.
slice_networkpolicy_violation	The namespace isolation policy violation of the slice for which the metric is recorded.
slice_project	The name of the project on which the slice is created.
slice_reporting_controller	The name of the reporting controller. The value is controller for all the KubeSlice Controller related metrics.
slice_workload_type	The workload type of the slice for which the metric is recorded.
