I am in the process of collecting some sort of Linux Kernel activities. I have placed multiple printk statements with in the kernel source code and would like to monitor those during regular kernel activities. Unfortunately, I have realized that the Kernel Log Buffer size (CONFIG_LOG_BUF_SHIFT) cannot be more that 2^21 which is essentially equal to 2M entries.
Is there any other way to record more than 2M Kernel messages ?
