Hi:
I am a new fish, I have tried my best to find answer about my question on
web, but I failed. so
I come here to ask for your help. the below is my question:
I found that dpdk provides a api rte_eth_stats_get to read packet
statistics about the interface, includes total input/output
unicast/multicast/brodcast packets/bytes. but the api does not work on
VMxnet interface (which is a virtual interface in VMware machine).
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.

Probably something in your app or environment rather than in the API
itself. 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 am so happy to get your reply.
My dpdk version is 2.1，and the OS is centOS 7。
the following is the output from "dpdk_nic_bind.py --status":

That's a different virtual NIC than what I'm running in my VMs, but given
your app isn't working directly on the hardware, I doubt that's the issue.
In case it helps along the way, here's what I see in my VM:
$ dpdk_nic_bind.py --status

With it not working on hardware and you having devices successfully bound
to DPDK, maybe it's a problem in your app. Have you tried running any of
the sample apps that use rte_eth_stats_get() and see if it works there?

Hi, Jay:
My apologies for taking me to get back to you.
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.
