I want to get the memory consumption by a process. I am using RSS parameter to determine it.

I am getting same RSS value when I am using pmap -xx pid and with smem tool.
But when I am using ps v pid to get the RSS then it is showing different value.

I know for pmap and smem they use /proc/pid/smaps file to get RSS value but I don't have idea about ps tool.
What are the basis of this calculation in ps tool and which is correct ps or pmap and smem

linux memory ps pmap
