i am running into an space issue on my 64 bit Ubuntu running on Virtual machine even though the space available is 40 GB and total file system usage is 9.5 GB it shows me total usage 37 GB where is my remaining space being used ?
I am bit confuse between cpu usage and cpu load, Can anyone please explain me the basic difference between them and what formula should we use to calculate them on Linux?
I am accessing /proc/stat file to calculate cpu usage.
I'm looking for a good way to get the current total bandwidth usage on a linux machine, i've tried iftop, nethogs, but they doesn't show real bandwidth usage (compared to system monitor), anyway they doesn't suit to my project I want a command which I execute and it returns the current usage for upload and download and nothing else.
By getting Memtotal and Memfree values from "/proc/meminfo" and subtracting them we must get the Used Memory in Linux. Most of threads and web pages that I have visited have guided through this approach to compute the Total Memory Usage in Linux. But by implementing this method, I get different results with GNOME System Monitor! My result is greater than that (approximately double).
My server running magento is 4gb ram and 4 core cpu. But still i am struggling with the high CPU usage. I only have 10 visitors at any given point of time. I am not sure if the PHP has to take this high % CPU usage.
