Hi kernel gurus, I am trying to find out the memory that's used on my linux box. I find that there are quite a few confusing metrics. How do I find out the "true" used memory ? 1. For eg. "free -m" shows free memory (excluding buffers/caches) as 308 MB while I can see(from "df" output) that the the tmpfs partitions take up about 400 MB. So, does "free -m" not consider the tmpfs partitions ? 2. I try to add up RSS field of all processes reported by "ps aux" command. But is it true that this would be misleading in that, shared memory used by, say 2 processes would show up twice here although there's only one copy in memory. Also does this consider the fact that there's only one copy of shared libraries ? 3. I guess "free -m" and "top" commands use /proc/meminfo and hence all these outputs are same ? Thanks, Ravi -
