Well, that is the problem exactly - I need to get info every second to track traffic bursts, i.e. depth of precision should be on seconds level. So, in my case I`ll have to either poll it every second - or approximate it by computing an average…

Thanks a lot for your answers!

You don't _have to_ poll every seconds, you can poll every minute and  
compute an average. That really depends on what precision you need.  

You can do the same things with the existing samples provided by
