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
For terminals with 256 color support
_, graded colors can be displayed by
passing the --colors flag.
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::
Usage: tmux-mem-cpu-load [OPTIONS]
Available options:
-h, --help
Prints this help message
-c, --colors
Use tmux colors in output
-p, --powerline-left
Use powerline left symbols throughout the output, enables --colors
-q, --powerline-right
Use powerline right symbols throughout the output, enables --colors
-v, --vertical-graph
Use vertical bar chart for CPU graph
-l <value>, --segments-left <value>
Enable blending bg/fg color (depending on -p or -q use) with segment to left
Provide color to be used depending on -p or -q option for seamless segment blending
Color is an integer value which uses the standard tmux color palette values
-r <value>, --segments-right <value>
Enable blending bg/fg color (depending on -p or -q use) with segment to right
Provide color to be used depending on -p or -q option for seamless segment blending
Color is an integer value which uses the standard tmux color palette values
-i <value>, --interval <value>
Set tmux status refresh interval in seconds. Default: 1 second
-g <value>, --graph-lines <value>
Set how many lines should be drawn in a graph. Default: 10
-m <value>, --mem-mode <value>
Set memory display mode. 0: Default, 1: Free memory, 2: Usage percent.
-t <value>, --cpu-mode <value>
Set cpu % display mode. 0: Default max 100%, 1: Max 100% * number of threads.
-a <value>, --averages-count <value>
Set how many load-averages should be drawn. Default: 3
Blending Dynamic Colors Tmux Powerline Segments
===============================================
The -l and -r options when used in conjunction with a recent version of Tmux Powerline
that has the ability to selectively disable spacing and separators between segments allow
for seamless blending of tmux-mem-cpu-load output with other adjacent segments. The end
result is dynamic changing of appropriate foreground and background colors as the start
and end of the tmux-mem-cpu-load output string that is aggregated with other Tmux
Powerline output to produce a more polished status line in Tmux.
Segment Adjaceny before this feature:
.. image:: seg-adj1.png
Segment Adjaceny after this feature:
.. image:: seg-adj2.png
Note that the values for the -l and -r options will be the standard Tmux integer color
values. They set the appropriate background and foreground colors used for the separator
character when used with the poweline-left or powerline-right options so it is easy to
match coloring to adjacent segments. An example from the segment script that calls
tmux-mem-cpu-load is as follows::
tmux-mem-cpu-load -q -v -l 52 -r 33
This combines with theme options available to tmux-powerline, such as the following::
"disk_usage_cust 52 123 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 52 123 right_disable" \
"tmux_mem_cpu_load_cust 52 234 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 52 234 both_disable separator_disable" \
"batt_cust 33 154 ${TMUX_POWERLINE_SEPARATOR_LEFT_BOLD} 16 33 N separator_disable" \
