You can get it with "sar -B" if you've installed the sysstat package. If you're running collection then running "sar -B" will show you today's history. If you want to see what is happening now you can do something like "sar -B 5 5".

Type "man sar" for more information. If you don't have sar you can get it by installing the sysstat package.

I am running Debian on an NSLU2 which has very little RAM and using flash for virtual memory. vmstat shows 0 pagein/pageouts per second which is good. Is there anyway to show the number of pagein/pageouts per day? Since last boot?
