1. A computer-implemented method for monitoring flow attributes at a network probe coupled to a first device in a network node, wherein the network probe collects flow information for export on behalf of the first device, the method comprising:
detecting, by a processor of a network probe coupled to a first device at the network node, first information indicative of transmission of a packet through the network node, the first information being discernible, at the network probe, from raw data contained within the packet, wherein the network probe comprises the processor and a memory and the first device comprises a second processor and a second memory, the processor and the memory of the network probe being different from the second processor and the second memory of the first device; determining, by the network probe, that the packet is not part of an existing flow; generating, in the memory of the network probe, a new flow entry corresponding to the packet; receiving, at the network probe, from the first device of the network node, second information associated with the transmission of the packet through the network node, the second information contained in a forwarding information base (FIB) stored in the second memory of the first device and which cannot be discerned, at the network probe, from information contained within the packet; and writing, in the memory of the network probe, the second information to the new flow entry corresponding to the packet. |
