Hi aLTeReGo and thank you for your reply.
Ah, ok, I get this - 1 ICMP ping every polling interval (2 minutes in my case)
Would you be able to help with understanding over what interval does the average is being calculated and how can I configure this value (if possible). You gave and example of 4 minutes above... where is this coming from?
Thank you very much for your time and help,
Alex
