oVirt gerrit 83796 0 master MERGED net: Logging failure to read the speed at debug level 2017-11-08 18:23:17 UTC

Description Lukas Svaty 2017-11-07 12:23:50 UTC 
Created attachment 1348932 [details]
vdsmd.log cut off

Description of problem:
$subj every 15 seconds, we can lower that

# tail -f /var/log/vdsm/vdsm.log | grep WARN
2017-11-07 13:19:41,489+0100 WARN  (periodic/1) [root] cannot read eth0 speed (nic:41)
2017-11-07 13:19:56,544+0100 WARN  (periodic/7) [root] cannot read eth0 speed (nic:41)

Adding vdsmd.log, not much I can read from it regarding this issue.

2 questions:
What is causing the warning?
How do we lower the frequency of logging it?
Comment 1 Yaniv Kaul 2017-11-08 07:03:23 UTC 
This only happens with virtio NICs, which simply do not advertise their speed.
Comment 2 Edward Haas 2017-11-08 16:21:57 UTC 
Changing the logging level to debug. Debug logs should not reach the journal.
Comment 3 Lukas Svaty 2017-11-13 13:20:28 UTC 
clean & clean:
# journalctl --unit vdsmd -p 0..4 -S today
# tail -f /var/log/vdsm/vdsm.log | grep WARN
