sFlow will get this for you if your switches support it however you will need a sFlow collector too.

Hi
Smart switches can do that for you usually (if they're smart enought) so I would rather look here.

And there's a lun_top tool on the NOW Toolchest for SAN configs.

Similar is 'cifs top' if you have cifs.per_client_stats.enable set to 'on'. However, it gives you top talkers based on username (you'd have to use 'cifs sessions' to get the machine name\IP) and only for the last 3 second rolling average (though there are other options).
Not really a way to get what you're looking for, to my knowledge...

If the traffic is nfs, and you have nfs.per_client_stats.enable, then nfsstats -l gives the number of nfs requests per host.

Hi,
When using "sysstat" from the command line, it's very easy to get an idea of the network throughput that is currently being handled by the filer, and with commands like "vif stat" it's easy to get an idea on the interfaces that are transmitting or receiving this traffic.
However, I am wondering if is it possible to get an idea on the client IP addresses that are generating most of the network traffic without having to resort to pktt every time, then copying over the capture file and analyzing it afterwards ?
Are there any counters availble from a command that show how much
traffic
a particular IP address has sent/received ? I tried various commands (eg. netstat has a few interesting options) but couldn't find anything that solved my
problem.
At the moment, if I need to determine the hosts that are using most of
the
iSCSI or NFS bandwidth, I have to resort to pktt, and I am looking for a
easier
way to achieve what I want. Ideally, I'd like to get information on the protocols and ports involved too, but having IP addresses would already be very useful.
Best regards, Filip
