I'm not sure this is all you want/need, but perhaps it is :) There is cat /proc/meminfo And also cat /proc/vmstat Then there's the slabinfo tool which can also show a lot of details: juhl@dragon:~/kernel/linux-2.6$ gcc -o slabinfo Documentation/vm/slabinfo.c juhl@dragon:~/kernel/linux-2.6$ ./slabinfo -h slabinfo 5/7/2007.
