Ps-mem - Another Memory Monitoring Tool
I have a new favourite memory monitoring tool. It provides a nice breakdown of the memory used by each running process, along with a total as shown below:
Private + Shared = RAM used Program

6.4 GiB + 482.6 MiB = 6.9 GiB qemu-system-x86_64 (17)
---------------------------------
8.3 GiB
=================================
This is in stark contrast to htop, which proved a whole lot less useful as demonstrated from the same server below:
Note: Observant readers may have noticed that htop is showing far more memory being utilized than the 8.3 GiB that ps-mem showed. For some reason, the ZFS ARC does not register in htop, top, or ps-mem it seems.
Installation
wget https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py
sudo mv ps_mem.py /usr/sbin/ps-mem
sudo chmod +x /usr/sbin/ps-mem
Usage
General
sudo ps-mem
Non-grouped
If you don't want similar processes to be grouped (such as my qemu-system in the example above), then run:
sudo ps-mem --split-args
More usage information can be found on the developer's Github page.
