Abstract: Some mbodiments provide a method for an agent executing on a Kubernetes node in a cluster. The method instructs a forwarding element that also executes on the node to process a flow tracing packet. From the forwarding element, the method receives a message indicating a set of flow entries matched by the flow tracing packet as the forwarding element processes the flow tracing packet. For each flow entry of at least a subset of the flow entries matched by the flow tracing packet, the method generates mapping data that maps elements of the flow entry to Kubernetes concepts implemented in the cluster. The method reports data regarding the set of flow entries along with the generated mapping data.
