RELATED: How to Use the free Command on Linux The vmstat Command You can also use the following nifty trick we tweaked from one of our readers to see the percentage of swap space that is used: free -m | grep Swap | awk '' Free: The amount of remaining (unused) swap space.Used: The amount of swap space that’s in use.Total: The size of the swap partition or file.The Swap columns contain the following information:

LINUX LIST PROCESSES BY RAM USAGE SOFTWARE

Available: This is an estimate of the memory that’s available to service memory requests from applications and any other operational software on your computer.

This can be released quickly by the kernel if required.

Buff/cache: Amount of memory used for buffers and cache.

Shared: Amount of memory used by the tmpfs file systems.

Used: The sum of Free+Buffers+Cache subtracted from the total amount.

Total: The total amount of physical RAM on this computer.

The Mem columns contain the following information: 7.2.This is the output we get: total used free shared buff/cache available We just need to remember to divide by 1000’s, not 1024’s because that’s the difference between Kilo and Mega. To check the PSS memory on a Linux process, we have to access the /proc/' Tasks: 351 total, 1 running, 350 sleeping, 0 stopped, 0 zombie Tasks: 350 total, 1 running, 349 sleeping, 0 stopped, 0 zombie – which are allocated more or fewer resources as the CPU sees fit: top - 22:55:50 up 4:41, 1 user, load average: 0,82, 2,25, 2,72 As we can see in the terminal, there are multiple chrome processes that run and it makes sense because there really are multiple processes that run – the actual chrome application, the opened tabs, maybe some downloads through the browser downloader, etc.

For example, if we look at the process with the PID 12408 (google chrome instance in this case), we can see the differences in, for example, %CPU which shows how much of the CPU that particular process is using.
