1. A method, comprising:
obtaining, at a sampling aggregator device from one or more packet forwarding devices in a network, first-stage sampling information associated with a packet at a first stage of a packet forwarding path;
obtaining, at the sampling aggregator device from the one or more packet forwarding devices, second-stage sampling information associated with the packet at a second stage of the packet forwarding path;
determining, by the sampling aggregator device, aggregate sampling information based on the first-stage sampling information and the second-stage sampling information;
determining, by the sampling aggregator device and from the aggregate sampling information, at least one of an Internet protocol version 6 (IPv6) segment routing header (IPv6SRH) segment information associated with the packet or a segment list associated with the packet;
transmitting, by the sampling aggregator device to a sampling analyzer device, the aggregate sampling information;
indicating, by the sampling aggregator device and to the sampling analyzer device via the aggregate sampling information, the at least one of the IPV6SRH segment information associated with the packet or the segment list associated with the packet; and
causing, by the sampling aggregator device, the sampling analyzer device to modify network device configurations using the aggregate sampling information.
