Dropped packets - how many is normal?
So I recently started playing with netdata. Turns out one of my KVM servers is dropping a lot of incoming packets - consistently around 50-60 each second.
The server is basically idle. I can see the dropped count increasing with
watch ifconfig ens3 looking under RX/dropped.
I did try exploring with tcpdump: it shows lots of ARP and "ICMP6 neighbor solicitation" packets. The server has IPv6 disabled at the kernel, so I guess I should expect a few dropped packets from that, but 60/second seemed surprising!
