I am not sure if this api works for the real interface. who has more information about this, and why it does not work on virtual machine ? Appreciate any comments and reply. ^ permalink raw reply [flat|nested] 5+ messages in thread

We run rte_eth_stats_get() against interfaces in VMware Fusion, VirtualBox and real hardware and they all work generally. Need some info before anyone can help you much: * What version of DPDK are you running? * What OS are you running on? * Output from "dpdk_nic_bind.py --status"?

I tried the sample apps on my environment follow your advice, and I found it works well. so I started to compare the code related to the api between my app and the sample app, I didn't find any significative difference. I am very confused. ..... finnaly, with the help of my colleague, I tracked down the problem. It's a confused character of my platform that make the packets miss the interface which I monitored. so I can access the IP of the interface, but the flow don't pass through the interface. after ajusting the topology, the api works well. anyhow, thanks to your advice, I tracked down the problem. so again, I appreciate your time in talking with me about this api.
