Abstract: Techniques for determining packet path visibility, packet drops, and latency measurements associated with data flows of a networked computing environment are disclosed herein. The techniques may include receiving flow data associated with a data flow of a networked computing environment and determining a packet path associated with the data flow. The packet path may indicate that a first leaf switch is configured to send packets to a service chain device and that a second leaf switch is configured to receive the packets from the service chain device. The techniques may also include receiving timestamp data indicating a first time when the first leaf switch sent a packet to the service chain device and a second time when the second leaf switch received the packet from the service chain device. Based at least in part on the timestamp data, a latency associated with the service chain device may be calculated.

Abstract: A system and method for providing end-to-end data flow analytics in a network flow that includes network appliances. Information regarding one or more network appliances is received by a flow collector and analyzed by an enrichment module. The network information regarding the one or more network appliances can be stored. Network flow data is received from various nodes within the network and stitched or aggregated in light of the enriched network appliance information to provide an end-to-end data flow that can be useful to understand one or more performance parameters of the unified network flow.
