I am using netdata to monitor my PVE hosts. On some of them I am getting inbound_packets_dropped_ratio warnings because 2 % of packets are dropped. Any idea why?
Here is my setup:
Each host has 2 NICs, first is mapped to vmbr0, second to vmbr1.
vmbr1 is only used for PVE traffic. It is connected to a switch which only connects to other VPE hosts of the same cluster. No router. I guess we can ignore it.
vmbr0 is VLAN aware and used for VMs as well as for some PVE traffic.
vmbr0.19 is used to access the PVE frontend. This is where the package drops happen.
All VMs have a VLAN tag configured.
Here is my config:

Code:
cat /etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
