Bug report summary

When a Netdata slave is rebooted, the IP bandwidth counter displays correctly on the slave's dashboard. However, when the slave is viewed from the master's dashboard, there's a huge spike (3.8 Gbps) just after the reboot. This is on a system with a gigabit interface. There are other systems where a reboot causes an even higher spike like 2 million terabits/s.

Master

Slave

OS / Environment

Debian Stretch

Netdata version (ouput of netdata -V)

netdata 1.11.1+dfsg-2

Component name

proc_net plugin

Steps To Reproduce

Set up netdata in a master-slave configuration and reboot the slave. Watch the dashboard provided by the master and see the bandwidth spike up after the reboot has completed.

Expected behavior

Netdata should handle the interface reset correctly and not display unrealistic values.
