OS: Ubuntu 14.04.3 Kernel: 3.13.0
I am running Linux Virtual Server (with keepalived) on that server. All ok. As of today, there is more network traffic on the LVS, and at the same time I start seeing the following Linux kernel log entries (in
dmesg) every few minutes:
net_ratelimit: n callbacks suppressed
where n is a integer number.
is written the solution to disable the kernel network code log message rate limiting with the following command:
sysctl -w net.core.message_cost=0
After issuing this command, the above mentioned "callbacks suppressed" messages do not occur anymore, and the
/var/log/syslog stays empty as it used to be. Also
dmesg command does not show anything anymore.
But what I want is to see the messages that have been subject to the log message rate limiting, because I guess there is a network problem that leads to the high amount of log messages. It looks like these messages are not logged. How can I see that messages?
