Metrics Reference
Kubewarden exposes some relevant metrics that enhance visibility of the platform, and allows cluster administrators and policy developers to identify patterns and potential issues.
Policy Server​
The Policy Server is the component that initializes and runs policies. Upon receiving requests from the Kubernetes API server, it will forward the request to the policy, and return the response provided by the policy to the Kubernetes API server.
Metrics​
note
Baggage are key-value attributes added to the metric. They are used to enrich the metric with additional information.
