Hi,

i am trying to measure free memory and real memory.

but values at dmesg.boot and sysctl  are diffrent.

# cat /var/run/dmesg.boot | grep real
real memory  = 268435456 (256 MB)

# sysctl vm.vmtotal  | grep Real
Real Memory:            (Total: 232792K Active 122448K)

As above, values are not equal,
so that, i cant trust the Free Memory value that sysctl gives.

how can i get right values?

with best regard,
Ozkan KIRIK
