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.

Example output:

1119/3819MB ▄  76.5% ▇

 ^    ^     ^    ^   ^
 |    |     |    |   |
 1    2     3    4   5

1. Currently used memory.
2. Available memory.
3. Memory usage bar graph.
4. CPU usage percentage.
5. CPU usage bar graph.

• >= cmake -2.6
• C++ compiler (e.g. gcc/g++)

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

cd <source dir>
cmake .
make

su -
make install
logout

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 #(tmux-mem-cpu 2 'fg=blue,bg=black,bright')#[default]"

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

An optional second argument is the default text foreground color.
