I'm a new comer. I'm not sure if I post my question in the right place but if it is please help me to change to the right box.
I have a question about how to calculate the amount of memory free in SUSE. With my understanding:
Total mem free = Memory free + Swap free + Buffer + Cached (I assume Swap is free memory as well in my calculation).
I also found this link in the internet http://blog.thewebsitepeople.org/201...eak-detection/ which state that:
Buffers + Cached = Active(file) + Inactive(file) + ?X?.
Thus, my formula would become:
Total mem free = Memory free + Swap free + Active(file) + Inactive(file) + ?X?.
1/ As the above link is not an official link from SUSE, I can not prove if the formula is correct. Do any one have any idea about my calculation?
2/ What does ?X? in the above formula stand for?
3/ I also noticed that tmpfs is used in my system, about 101MB, please see example below. So the total of memory free must exclude tmpfs. Is my calculation correct for this case as well? If not, any suggestion?
I would be very appreciated if someone could clarify my confuse as I hardly find these kind of information in the internet.
