conky

Name

conky — A system monitor for X originally based on the torsmo code, but more kickass. It just keeps on given'er. Yeah.

Synopsis

conky [options]

Description

Conky is a system monitor for X originally based on the torsmo code. Since it's original conception, Conky has changed a fair bit from it's predecessor. Conky can display just about anything, either on your root desktop or in it's own window. Conky has many built-in objects, as well as the ability to execute programs and scripts, then display the output from stdout.

We are always looking for help, and anyone interested in becoming a developer is welcome. Please use the facilities at SourceForge to make bug reports, feature requests, and submit patches.

Thanks for your interest in Conky.

Compiling

For users compiling from source, make sure you have the X development libraries installed. This should be a package along the lines of "libx11-dev or xorg-x11-dev".

Gentoo users -- Conky is in Gentoo's Portage... simply use "emerge app-admin/conky" for installation. There is also usually an up-to-date ebuild within Conky's package or in CVS.

Debian,etc. users -- Conky will be in Debian's repositories soon (by mid-September, hopefully), and then Ubuntu shortly thereafter. Until then, "dpkg -i" the .deb package to install.

Example to compile and run Conky with all optional components (note that some configure options may differ for your system):

sh autogen.sh # Only required if building from CVS
./configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --enable-xft --enable-seti --enable-double-buffer --enable-own-window --enable-proc-uptime --enable-mpd --enable-mldonkey --enable-x11 --enable-portmon
make
make install # Optional
src/conky

Conky probably doesn't compile with compilers other than gcc and icc. It doesn't compile with C89 compiler and not even with pure C99. It uses a few things that might not exist: strdup(), strcasecmp(), strncasecmp(), optarg variable with getopt() and long long (not in C89). Crashes in file system statistics stuff when compiled with icc, I don't know exactly why.

You can disable 'drawing to own window' feature in case you don't need it by passing --disable-own-window to configure -script.

You Should Know

Conky is generally very good on resources. However, certain objects in Conky are harder on resources then others. In particular, the $tail, $top, $font, and $graph objects are quite costly in comparison to the rest of Conky.

If you do use them, please do not complain about memory or CPU usage, unless you think something's seriously wrong (mem leak, etc.).

An easy way to force Conky to reload your ~/.conkyrc: "killall -SIGUSR1 conky". Saves you the trouble of having to kill and then restart.

IMPORTANT: For previous Conky users, Conky 1.3 no longer supports the metar stuff. mdsplib was causing way too many problems. Hopefully there'll be a better solution in Conky 2.x...

Options

Command line options override configurations defined in configuration file.

-v | -V: Prints version and exits
-a ALIGNMENT: Text alignment on screen, {top,bottom}_{left,right} or none
-b: Use double buffering (eliminates "flicker")
-c FILE: Config file to load instead of $HOME/.conkyrc
-d: Daemonize Conky, aka fork to background
-f FONT: Font to use
-h: Prints command line help and exits
-o: Create own window to draw
-t TEXT: Text to render, remember single quotes, like -t ' $uptime '
-u SECONDS: Update interval
-w WIN_ID: Window id to draw
-x X_COORDINATE: X position
-y Y_COORDINATE: Y position

Configuration Settings

Default configuration file is $HOME/.conkyrc (can be changed from conky.c among other things). See conkyrc.sample. If installing from Debian package, this should be in /usr/share/doc/conky/examples ("gunzip conkyrc.sample.gz" to get conkyrc.sample).

You might want to copy it to $HOME/.conkyrc and then start modifying it. Other configs can be found at http://conky.sf.net

alignment: Aligned position on screen, may be top_left, top_right, bottom_left, bottom_right, or none

Variables

Colors are parsed using XParsecolor(), there might be a list of them: /usr/X11R6/lib/X11/rgb.txt. Also, http://sedition.com/perl/rgb.html. Color can be also in #rrggbb format (hex). Note that when displaying bytes, power is 1024 and not 1000 so 1M really means 1024*1024 bytes and not 1000*1000.

tcp_portmon port_begin port_end item (index) (ip4 only at present)

TCP port monitor for specified local ports. Port numbers must be in the range 1 to 65535. Valid items are:

count - total number of connections in the range

rip - remote ip address

rhost - remote host name

rport - remote port number

lip - local ip address

lhost - local host name

lservice - local service name from /etc/services

The connection index provides you with access to each connection in the port monitor. The monitor will return information for index values from 0 to n-1 connections. Values higher than n-1 are simply ignored. For the "count" item, the connection index must be omitted. It is required for all other items.

Examples:

${tcp_portmon 6881 6999 count} - displays the number of connections in the bittorrent port range

${tcp_portmon 22 22 rip 0} - displays the remote host ip of the first sshd connection

${tcp_portmon 22 22 rip 9} - displays the remote host ip of the tenth sshd connection

${tcp_portmon 1 1024 rhost 0} - displays the remote host name of the first connection on a privileged port

${tcp_portmon 1 1024 rport 4} - displays the remote host port of the fifth connection on a privileged port

${tcp_portmon 1 65535 lservice 14} - displays the local service name of the fifteenth connection in the range of all ports

Note that port monitor variables which share the same port range actually refer to the same monitor, so many references to a single port range for different items and different indexes all use the same monitor internally. In other words, the program avoids creating redundant monitors.

texeci interval command

Runs a command at an interval inside a thread and displays the output. Same as $execi, except the command is run inside a thread. Use this if you have a slow script to keep Conky updating. You should make the interval slightly longer then the time it takes your script to execute. For example, if you have a script that take 5 seconds to execute, you should make the interval at least 6 seconds. See also $execi.

offset (pixels)

Move text over by N pixels. See also $voffset.

tail logfile lines (interval)

Displays last N lines of supplied text text file. If interval is not supplied, Conky assumes 2x Conky's interval. Max of 30 lines can be displayed, or until the text buffer is filled.

time (format)

Local time, see man strftime to get more information about format

totaldown net

Total download, overflows at 4 GB on Linux with 32-bit arch and there doesn't seem to be a way to know how many times it has already done that before conky has started.

top type, num

This takes arguments in the form:top (name) (number) Basically, processes are ranked from highest to lowest in terms of cpu usage, which is what (num) represents. The types are: "name", "pid", "cpu", and mem". There can be a max of 10 processes listed.

top_mem type, num

Same as top, except sorted by mem usage instead of cpu

totalup net

Total upload, this one too, may overflow

updates Number of updates

for debugging

upspeed net

Upload speed in kilobytes

upspeedf net

Upload speed in kilobytes with one decimal

upspeedgraph net (height),(width) (gradient colour 1) (gradient colour 2) (scale)

Upload speed graph, colours defined in hex, minus the #. If scale is non-zero, it becomes the scale for the graph.

uptime

Uptime

uptime_short

Uptime in a shorter format

seti_prog

Seti@home current progress

seti_progbar (height),(width)

Seti@home current progress bar

seti_credit

Seti@home total user credit

voffset (pixels)

Change verticle offset by N pixels. Negative values will cause text to overlap. See also $offset.

Examples

conky -t '${time %D %H:%m}' -o -u 30: Start Conky in its own window with date and clock as text and 30 sec update interval.
conky -a top_left -x 5 -y 500 -d: Start Conky to background at coordinates (5, 500).

Files

~/.conkyrc default configuration file

Bugs

Drawing to root or some other desktop window directly doesn't work with all window managers. Especially doesn't work well with Gnome and it has been reported that it doesn't work with KDE either. Nautilus can be disabled from drawing to desktop with program gconf-editor. Uncheck show_desktop in /apps/nautilus/preferences/. There is -w switch in Conky to set some specific window id. You might find xwininfo -tree useful to find the window to draw to. You can also use -o argument which makes Conky to create its own window.
