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.
