Hi
I want to write a script to find free memory available for use by
applications. The following is the output of 'free' command in one of
our lab machines.
total used free shared buffers cached
Mem: 3804 3706 98 0 107 3488
-/+ buffers/cache: 110 3694
Swap: 996 0 996
Total: 4801 3706 1094
Most of the physical memory has been allocated to Memory cache. Should i
consider this memory while calculating free memory assuming that Kernel
decreases memory given to cache and buffers and increases memory for use
by applications when ever they need more memory.
Is the below calculation valid?
Total Free Memory Available for Applications = free + buffers + cached
Thanks,
Shashank
