about sflow samples?

[turbomemory]

I have configured two samples of sflow on the switch at the same time: flow and counter.
Can goflow2 (goflow2-2.2.1-windows-x86_64.exe) only get flow samples?

no counter sampling data，why？

thx

Hello,
GoFlow2 converts samples into a unified flattened protobuf. Unfortunately counters are not supported for this conversion. This is not a bug.

You can get a JSON structure for those counter messages by using the flag -producer=raw.

Hope this helps.

thank you @lspgn

now，counter sampling is ok with “-produce raw.”

but... previously I used inmon's sflowtool to capture both flow sampling and counter sampling.
It seems that goflow2 cannot run sample and raw at the same time on the same host to get real-time data. 



Is there any way for goflow2 to get flow and counter samples at the same time?

ps：I didn't find any guidance in the doc and --help。

Hi @turbomemory,
Unfortunately, there are no way to get both at the same time. Samples do get converted but you would need extra processing since it would just be the base64 of the packet header.
I do not have the bandwidth to create a new producer that would combine both (+ handle special use case since raw can only be converted to JSON and not protobuf).

An alternative solution would be to mirror the UDP you're receiving into two GoFlow2 processes (one in each decoding mode):

• with nftables
• with iptables
