Next to your container logs, we now also ship Kubernetes events (kubectl get events -n <namespace>) to Grafana Loki. You can query these via {app="eventrouter", namespace="<mynamespace>"}.
From Kubernetes docs:
Kubernetes events are objects that provide insight into what is happening inside a cluster, such as what decisions were made by scheduler or why some pods were evicted from the node. You can read more about using events for debugging your application in the Application Introspection and Debugging section.
