Abstract
An orchestrator can send trace directives to network appliances that indicate a network flow to trace. The network appliances can include packet processing pipelines that each include numerous processing stages. The network appliances implement network rules for processing network flows by configuring the pipeline's processing stages to execute specific policies for specific network packets in accordance with the network rules. The processing stages can also be configured to produce metadata indicating the policies implemented at each stage to process certain network packets in network flows indicated by trace directives. The metadata can be used to produce a trace report that indicates a network packet of the network flow, a first network rule that was applied to the network packet by a one of the first appliance processing stages, and the one of the first appliance processing stages that applied the first network rule to the network packet.
