What is kernel ring buffer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I need to clear my concept related with loglevels
associated with printk statement.

When I say 

printk("<1> Hello World");

The output is not flushed to my console and I have to
explicitly execute dmesg to see the printk output.
WHat is a reason that the output is not coming
directly to console.

>From where dmesg reads its input and how dmesg and
klogd are associated ? 

I have used echo 8 > /proc/sys/kernel/printk to set
the console default level to 8 and hence I was
expecting that loglevel 1 will cause the output to be
displayed on console.

Is klogd is a specialized case of syslogd ?

Regards
Dinesh
