A method for optimizing telemetry packet for in-band telemetry includes receiving a telemetry packet at a network node in a communication pathway between a sending host sending data packets to a receiving host and determining telemetry data for the network node. The telemetry data includes latency information for data packet processing of the network node. The method includes adding metadata to the telemetry packet, where the metadata is added after a header and a telemetry packet header and after any metadata added by any upstream network nodes. The metadata includes the telemetry data and the metadata overwrites a portion of a payload of the telemetry packet. The method includes, in response to adding the metadata to the telemetry packet, transmitting the telemetry packet to a next destination.
