Dear All, my customer using UDP for their application, and found some packet loss, the occurrent is random, I hope to use dtrace to trace the problem, now I use udp_send_data:ipOutDiscards to monitor the packet loss in UDP/IP layer, I also hope to monitor the packet loss in NIC layer, the NIC driver is e1000g, which probe can I used for monitoring the packet loss in NIC layer? Thanks very much for any suggestions. Lily -- This message posted from opensolaris.org
