Good day, I am working on an academic project which involves obtaining statistics on the kernel's VM swapping behaviour. May I know what is the best way to do so (for either 2.2.15 or 2.4.17)? Specifically, I need to measure statistics such as the average number of times a page is swapped into memory, a measure of the average time period for which a page waits on disk between reads, etc. I tried doing this by writing to the kernel log (via "printk()") for each swap-in/swap-out, but I found that the log buffer was constantly being overflowed (thus losing information), even when I had enlarged the buffer. Therefore I would like to know if there is a better way. Also, what are the precautions I need to take when hacking on the VM code of either the 2.2 or 2.4 series kernels?
