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.

|
|
|
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
|
|
|
|
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.
|
|
|
|
