Hi!

Please, could you tell me why Icmp.LastPingTime and Icmp.AvgPingTime parameters return response times don't match with ping command?

This is the output for linux ping command:
[root@NetFlow1 ~]# ping -v -i 10 10.45.252.62

Attached image wich Icmp.AvgPingTime and Icmp.LastPingTime delivers at the same time.

Seems that divide it by 10 and then round value.


Best regards.
