## Change Errors generated by GKE applications (that is, applications with a[MonitoredResource](https://cloud.google.com/logging/docs/reference/v2/rest/v2/MonitoredResource) type of `k8s_container`) now support additional labels for metadata extraction. The values of the following labels will now appear in the resource filter and in various tables and displays on **Error Reporting** pages in the Google Cloud console: * The `app` value from your [GKE YAML configuration](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/) is now used for the primary resource label (also referred to as "service"). * The `pod_name` label of the [k8s\_container](https://cloud.google.com/logging/docs/api/v2/resource-list#tag%5Fk8s%5Fcontainer) monitored-resource type is now used for the secondary resource label (also referred to as "version"). We continue to support the use of the YAML `metadata` labels `k8s-pod/serving_knative_dev/service` and`k8s-pod/serving_knative_dev/revision`. These labels are prioritized for users already using them over the `k8s-pod/app` and `pod_name` labels described in this note. But we encourage users to begin using the new labels. If you do not set the `k8s-pod/app` label, GKE application errors continue to use the default service name of `gke_instances`.
