A cross-platform graphical process/system monitor with a customizable interface and a multitude of features. Supports Linux, macOS, and Windows. Inspired by both gtop and gotop.
Terminal: Kitty Terminal, Font: IBM Plex Mono, OS: Arch Linux. Theme based on gruvbox (see sample config).
Features
Features of bottom include:
-
CPU widget to show a visual representation of per-core (and optionally average) usage.
-
Memory widget to show a visual representation of both RAM and SWAP usage.
-
Networks widget to show a log-based visual representation of network usage.
-
Sortable and searchable process widget. Searching supports regex, and you can search by PID and process name.
-
Disks widget to display usage and I/O per second.
-
Temperature widget to monitor detected sensors in your system.
-
Flags to customize the display.
-
Config file support for custom colours and default options.

Config files

Installation
In all cases you can install the in-development version by cloning from this repo and using cargo build --release
. This is built and tested with Rust Stable (1.41 as of writing).
In addition to the below methods, you can manually build from the Releases page by downloading and building.
I officially support and test 64-bit versions of Tier 1 Rust targets. I will try to build and release 32-bit versions for Linux and Windows, but as of now, I will not be testing 32-bit for validity beyond building.
Cargo
cargo install bottom

Usage
Run using btm
.
Command line options
-
-h
,--help
shows the help screen and exits. -
-a
,--avg_cpu
enables also showing the average CPU usage in addition to per-core CPU usage. -
-m
,--dot-marker
uses a dot marker instead of the default braille marker. -
Temperature units (you can only use one at a time):
-
-c
,--celsius
displays the temperature type in Celsius. This is the default. -
-f
,--fahrenheit
displays the temperature type in Fahrenheit. -
-k
,--kelvin
displays the temperature type in Kelvin.
-
-
-v
,--version
displays the version number and exits. -
-r <RATE>
,--rate <RATE>
will set the refresh rate in milliseconds. Lowest it can go is 250ms, the highest it can go is 2128 - 1. Defaults to 1000ms, and lower values may take more resources due to more frequent polling of data, and may be less accurate in some circumstances. -
-l
,--left_legend
will move external table legends to the left side rather than the right side. Right side is default. -
-u
,--current_usage
will make a process' CPU usage be based on the current total CPU usage, rather than assuming 100% CPU usage. -
-g
,--group
will group together processes with the same name by default (equivalent to pressingTab
). -
-S
,--case_sensitive
will default to matching case. -
-W
,--whole
will default to searching for the world word. -
-R
,--regex
will default to using regex. -
--cpu_default
,--memory_default
,--disk_default
,--temperature_default
,--network_default
,--process_default
will select the corresponding widget on startup. By default the process widget is selected. -
-s
,--show_disabled_data
will show data entries in the graph legends even if the lines for that entry are disabled. -
-C
,--config
takes in a file path leading to a TOML file.
Keybindings
General
-
q
,Ctrl-c
to quit. Note if you are currently in the search widget,q
will not work so you can still type. -
Esc
to close a dialog window, widget, or exit maximized mode. -
Ctrl-r

again to unfreeze. Note that monitoring will still continue in the background. -
Ctrl/Shift
-arrow orH/J/K/L
to navigate between widgets. Note that on macOS, some keybindings may collide with existing ones;H/J/K/L
should work however. -
Up
ork
andDown
orj
scrolls through the list if the widget is a table (Temperature, Disks, Processes). -
?
to get a help screen explaining the controls. Note all controls exceptEsc
to close the dialog will be disabled while this is open. -
gg
orHome
to jump to the first entry of the current table. -
G
(Shift-g
) orEnd
to jump to the last entry of the current table. -
Enter
on a widget to maximize the widget.
CPU
/

.
Processes
-
dd
to kill the selected process -
c
to sort by CPU usage. Sorts in descending order by default. Press again to reverse sorting order. -
m
to sort by memory usage. Sorts in descending order by default. Press again to reverse sorting order. -
p
to sort by PID. Sorts in ascending order by default. Press again to reverse sorting order. -
n
to sort by process name. Sorts in ascending order by default. Press again to reverse sorting order. -
Tab
to group together processes with the same name. Disables PID sorting.dd
will now kill all processes covered by that name. -
