Measuring Free memory

[Mario Lobo]

Hi to all;

I am trying to get the most precise reading I can of all free memory (8-
STABLE).

I am using 
/usr/bin/vmstat | grep -a 2 | awk '{print $5}'

But I'm not sure if this reflects ALL free memory.

Would anyone have a more precise place to read free memory from?

Thanks
