Hi,<= /div>

Thanks for the reply, I know about top, but top do= es not help much in arriving at the total memory consumption.

I need the physical memory usage breakup of each process during= bootup, with a segregate of user and kernel allocation.

1) If I add up all "Pss" field in "proc/<PID>/smaps, do I get = the total Used memory?

2) Is the Pss value includes the kernel si= de allocation as well?

3) What fields I should choose from /proc/= meminfo" to correctly arrive at the "Used" memory in the system?

= 4) What about the memory allocation for kernel threads during booting? Why = does its Pss/Rss value shows 0 always

I already tried adding up all "PSS" values in every PIDs, but stil= l it does not match any where near to the total used memory in the system.<= /div>

Please help.

Thanks,

Pintu

How about htop, top or
"valgrind --tool massif"
