redirect watchdog messages to log file, not to console (screen)
 

I realy need your help, for redirect the messages from watchdog to log file, I'm recive a lot of messages on console on all clients, my server have RHEL7

Jan 27 12:24:05 prod kernel: NMI watchdog: BUG: soft lockup - CPU#7 stuck for 22s! [migration/7:43]
Jan 27 12:24:06 prod kernel: NMI watchdog: BUG: soft lockup - CPU#42 stuck for 22s! [ps:53836]
Jan 27 12:24:08 prod kernel: NMI watchdog: BUG: soft lockup - CPU#5 stuck for 22s! [migration/5:33]
Jan 27 12:24:14 prod kernel: NMI watchdog: BUG: soft lockup - CPU#88 stuck for 22s! [migration/88:455]
Jan 27 12:24:16 prod kernel: NMI watchdog: BUG: soft lockup - CPU#66 stuck for 23s! [migration/66:344]

I put the following rule on /etc/rsyslog.cong but does not work, and the messages persist on console (screen)

kern.* /var/log/kern.log
after: systemctl restart rsyslog

Maybe watchdog need a special rule?, someone can help me!

Thanks a lot for your help

Wouldn't it be better to fix the bad code that is locking up in kernel mode?
