Bug Description
Version: 6.1
Steps to reproduce:
Unclear
Logs collected by atop sometimes miss data for some network interfaces. For example, see attached screenshot. The screenshot was taken with 'Maximum lines for interface statistics' set to 30 (using 'l' key). Here is the list of bridges on controllers in the affected environment: http://
Kernel info:
root@node-
Linux node-130.domain.tld 3.13.0-65-generic #106-Ubuntu SMP Fri Oct 2 22:08:27 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Atop uses /proc/net/dev as a source for network stats, so there are two possibilities:
* /proc/net/dev is missing interfaces
* atop misses to record some info from /proc/net/dev
Also attached atop log, where at the beginning data for all eth interfaces is missing, but an hour after the start it appears.
