Hi everyone, 
I've been trying to get Akvorado to work on my environmnet but I keep getting the flows to stop collecting, it seems like the issue is related to the number of exporters I have sending data, can someone please share the max number they have gotten to work and the flows/s rate without the system crashing?

Thanks in advance for your answers.

Hi Peter, 

Thanks for that link. I did read the spec, and while the definition itself is clear, the escape clause gives a lot of wiggle room:

"Hardware limitations may prevent an exact reporting of the underlying frame length, but an agent should attempt to be as accurate as possible.

I read that as, "the vendor will do whatever it pleases, and you should be grateful to receive a non-negative integer at all." I could be too cynical, though. 

Anyway, this particular vendor does other funny things (such as sometimes stripping the q-tag headers from the sampled frame; throttling the frame sampling on the box, but not adjusting the sampling interval in the sFlow exports) that make it a true joy to work with this gear. ;-) 

Cheers,
