Description

A simple, lightweight program provided for system monitoring in the status line of tmux.

The memory monitor displays the used and available memory.

The CPU usage monitor outputs a percent CPU usage over all processors. It also displays a textual bar graph of the current percent usage.

The system load average is also displayed.

Example output::

2885/7987MB [||||| ] 51.2% 2.11 2.35 2.44

^ ^ ^ ^ ^ ^ ^ | | | | | | | 1 2 3 4 5 6 7

1. Currently used memory.
2. Available memory.
3. CPU usage bar graph.
4. CPU usage percentage.
5. Load average for the past minute.
6. Load average for the past 5 minutes.
7. Load average for the past 15 minutes.

For terminals with 256 color support_, graded colors can be displayed by passing the --colors flag.

Installation

Dependencies

Currently, Linux, Mac OSX, FreeBSD, OpenBSD, and NetBSD are supported.

Building

* >= CMake_ -3.5
* C++ compiler with C++11 support (e.g. gcc/g++ >= 4.6)

Download
--------

There are links to the source code at the `project homepage`_.

Build
-----

::

  cd <source dir>
  cmake .
  make

Install
-------

::

  su -
  make install
  logout

Build and Install Using tpm_
-----------------------------

Include the plugin in your ``.tmux.conf``, the same file you'll set the
configuration in, below.

::

  set -g @plugin 'thewtex/tmux-mem-cpu-load'

Install with Package Managers
-----------------------------

* Gentoo: ``emerge tmux-mem-cpu-load``
* Homebrew: ``brew install tmux-mem-cpu-load``

Build and Install Using Antigen_
--------------------------------

Include the bundle in your ``.zshrc``

::

  antigen bundle thewtex/tmux-mem-cpu-load

Configuring tmux_
=================

Edit ``$HOME/.tmux.conf`` to display the program's output in *status-left* or
*status-right*.  For example::

  set -g status-interval 2
  set -g status-left "#S #[fg=green,bg=black]#(tmux-mem-cpu-load --colors --interval 2)#[default]"
  set -g status-left-length 60

If you installed using tpm, you must specify the full path to the
``tmux-mem-cpu-load`` script, like below::

  set -g status-right "#[fg=green]#($TMUX_PLUGIN_MANAGER_PATH/tmux-mem-cpu-load/tmux-mem-cpu-load --colors --powerline-right --interval 2)#[default]"

Note that the *interval* argument to `tmux-mem-cpu-load` should be the same number
of seconds that *status-interval* is set at.

Another optional argument is the number of bars in the bar graph, which
defaults to 10.  This can, for instance, be set to the number of cores in a
multi-core system.

The *colors* option will add graded colors for each of the measures.

The full usage::
