DESCRIPTION
With a single process, gkrellm manages multiple stacked monitors and supports applying themes to match the monitors appearance to your win-
dow manager, Gtk, or any other theme.
FEATURES
o SMP CPU, Disk, Proc, and active net interface monitors with LEDs.
o Internet monitor that displays current and charts historical port hits.
o Memory and swap space usage meters and a system uptime monitor.
o File system meters show capacity/free space and can mount/umount.
o A mbox/maildir/MH/POP3/IMAP mail monitor which can launch a mail reader or remote mail fetch program.
o Clock/calendar and hostname display.
o Laptop Battery monitor.
o CPU/motherboard temperature/fan/voltages display with warnings and alarms. Linux requires lm_sensors modules and Windows requires MBM.
o Multiple monitors managed by a single process to reduce system load.
o A timer button that can execute PPP or ISDN logon/logoff scripts.
o Charts are autoscaling with configurable grid line resolution, or
o can be set to a fixed scale mode.
o Separate colors for "in" and "out" data. The in color is used for CPU user time, disk read, forks, and net receive data. The out
color is used for CPU sys time, disk write, load, and net transmit data.
o Commands can be configured to run when monitor labels are clicked.
o Data can be collected from a gkrellmd server running on a remote machine.
o gkrellm is plugin capable so special interest monitors can be created.
o Many themes are available.

If a command has been configured to be launched for a monitor, then a button will appear when the mouse enters the panel of that monitor.
Clicking the button will launch the command.
A right button mouse click on the side or top frames of the gkrellm window will pop up a user configuration window where you can configure
all the builtin and plugin monitors. Chart appearance may be configured by right clicking on a chart, and right clicking on many panels
will open the configuration window directly to the corresponding monitor's configuration page.
OPTIONS
--help Displays this manual page.
-t, --theme dir
gkrellm will load all theme image files it finds in dir and parse the gkrellmrc file if one exists. This option overrides the load-
ing of the last theme you configured to be loaded in the Themes configuration window. Theme changes are not saved when gkrellm is
run with this option.
-g, --geometry +x+y
Makes gkrellm move to an (x,y) postition on the screen at startup. Standard X window geometry position (not size) formats are
parsed, ie +x+y -x+y +x-y -x-y. Except, negative geometry positions are not recognized (ie +-x--y ).
-wm Forces gkrellm to start up with window manager decorations. The default is no decorations because there are themed borders.
-w, --withdrawn
gkrellm starts up in withdrawn mode so it can go into the Blackbox slit (and maybe WindowMaker dock).
-c, --config suffix
Use alternate config files generated by appending suffix to config file names. This overrides any previous host config which may
have been setup with the below option.
-f, --force-host-config
If gkrellm is run once with this option and then the configuration or theme is changed, the config files that are written will have
a -hostname appended to them. Subsequent runs will detect the user_config-hostname and gkrellm_theme.cfg-hostname files and use
them instead of the normal configuration files (unless the --config option is specified). This is a convenience for allowing
remote gkrellm independent config files in a shared home directory, and for the hostname to show up in the X title for window man-
agement. This option has no effect in client mode.
-s, --server hostname
Run in client mode by connecting to and collecting data from a gkrellmd server on hostname
-P, --port server_port
Use server_port for the gkrellmd server connection.
-nc No config mode. The config menu is blocked so no config changes can be made. Useful in certain environments, or maybe for running
on a xdm(1) login screen or during a screensaver mode?
-demo Force enabling of many monitors so themers can see everything. All config saving is inhibited.
-p, --plugin plugin.so
For plugin development, load the command line specified plugin so you can avoid repeated install steps in the development cycle.
BUILTIN MONITORS
Charts
The default for most charts is to automatically adjust the number of grid lines drawn and the resolution per grid so drawn data will be
nicely visible. You may change this to fixed grids of 1-5 and/or fixed grid resolutions in the chart configuration windows. However, some
combination of the auto scaling modes may give best results.
Auto number of grids:
This means to scale the chart to draw as many grids as is necessary to show all the data on the chart without clipping.
Auto grid resolution has two meanings:
1) If using a fixed number of grids, it means to set the resolution per grid to the smallest value in a base to peak range that draws data
without clipping. The peak is the maximum data value encountered and the base is 1/5 the peak.
2) If using auto number of grids, it means to set the resolution per grid to a value such that drawing the peak value encountered requires
at least 5 grids to be drawn.
CPU Monitor
Data is plotted as a percentage. In auto number of grids mode, resolution is a fixed 20% per grid. In fixed number of grids mode, grid
resolution is 100% divided by the number of grids.
Proc Monitor
The krell shows process forks with a full scale value of 10 forks. The chart has a resolution of 10 forks/sec per grid in auto number of
grids mode and 50 forks/second maximum on the chart in fixed number of grids mode. The process load resolution per grid is best left at
1.0 for auto number of grids, but can be set as high as 5 if you configure the chart to have only 1 or 2 fixed grids.
Net Monitor
gkrellm is designed to display a chart for net interfaces which are up, which means they are listed in the routing table (however, it is
possible in some cases to monitor unrouted interfaces). One net interface may be linked to a timer button which can be used to connect and
disconnect from an ISP.
The timer button shows an off, standby, or on state by a distinctive (color or shape) icon.
ppp Standby state is while the modem phone line is locked while ppp is connecting, and the on state is the ppp link connected. The
phone line lock is determined by the existence of the modem lock file /var/lock/LCK..modem, which assumes pppd is using /dev/modem.
However, if your pppd setup does not use /dev/modem, then you can configure an alternative with:
ln -s /var/lock/LCK..ttySx ~/.gkrellm2/LCK..modem
where ttySx is the tty device your modem does use. The ppp on state is detected by the existence of /var/run/pppX.pid and the time
stamp of this file is the base for the on line time.
ippp The timer button standby state is not applicable to isdn interfaces that are always routed. The on state is isdn on line while the
ippp interface is routed. The on line timer is reset at transitions from isdn hangup state to on line state.
For both ppp and ippp timer button links, the panel area of the interface is always shown and the chart appears when the interface is
routed with the phone link connected or on line. The timer button Start Command must run in the background and this is automatically the
default for many ppp logon scripts. A couple of exceptions are wvdial and kppp which need to be explicitly backgrounded:
wvdail &
or
kppp -c Foo &
and the timer button Stop Command in these cases could be:
skill -c wvdial
or
kppp -k
Otherwise do not append the "&" on ppp Start Command entries that background themselves.
If the timer button is not linked to a net interface, then it can be used as a push on / push off timer
Net monitors can have a label so that the interface can be associated with the identity of the other end of the connection. This is useful
if you have several net connections or run multiple remote gkrellm programs. It can be easier to keep track of who is connected to who.
Mem and Swap Monitor
Here you are reading a ratio of total used to total available. The amount of memory used indicated by the memory monitor is actually a
calculated "used" memory. If you enter the "free" command, you will see that most of your memory is almost always used because the kernel
uses large amounts for buffers and cache. Since the kernel can free a lot of this memory as user process demand for memory goes up, a more
realistic reading of memory in use is obtained by subtracting the buffers and cached memory from the kernel reported used. This is shown
in the free command output in the "-/+ buffers/cache" line where a calculated used amount has buffers and cached memory subtracted from the
kernel reported used memory, and a calculated free amount has the buffers and cached memory added in.
While the memory meter always shows the calculated "used" memory, the raw memory values total, shared, buffered, and cached may be option-
ally displayed in the memory panel by entering an appropriate format display string in the config.
Units: All memory values have units of binary megabytes (MiB). Memory sizes have historically been reported in these units because memory
arrays on silicon have always increased in size by multiples of 2. Add an address line to a memory chip and you double or quadruple (a
multiplexed address) the memory size. A binary megabyte is 2^20 or 1048576. Contrast this with units for other stats such as disk capaci-
ties or net transfer rates where the proper units are decimal megabytes or kilobytes. Disk drive capacities do not increase by powers of 2
and manufacturers do not use binary units when reporting their sizes. However, some of you may prefer to see a binary disk drive capacity
reported, so it is available as an option.
Internet Monitor
Displays TCP port connections and records historical port hits on a minute or hourly chart. Middle button click on an inet chart to toggle
between the minute and hourly displays. There is a strip below the minute or hour charts where marks are drawn for port hits in second
intervals. Each inet krell also shows port hits with a full scale range of 5 hits. The left button toggle of extra info displays current
port connections.
For each internet monitor you can specify two labeled datasets with one or two ports for each dataset. There are two ports because some
internet ports are related and you might want to group them - for example, the standard http port is 80, but there is also a www web
caching service on port 8080. So it makes sense to have a http monitor which combines data from both ports. A possible common configura-
tion would be to create one inet monitor that monitors http hits plotted in one color and ftp hits in another. To do this, setup in the
Internet configuration tab:
http 80 8080 ftp 21
Or you could create separate monitors for http and ftp. Other monitors might be smtp on port 25 or nntp on port 119.
If you check the "Port0 - Port1 is a range" button, then all of the ports between the two entries will be monitored. Clicking the small
button on the Inet panels will pop up a window listing the currently connected port numbers and the host that is connected to it.
gkrellm samples TCP port activity once per second, so it is possible for port hits lasting less than a second to be missed.
File System Monitor
File system mount points can be selected to be monitored with a meter that shows the ratio of blocks used to total blocks available.
Mounting commands can be enabled for mount points in one of two ways:
If a mount point is in your /etc/fstab and you have mount permission then mount(8) and umount(8) commands can be enabled and executed for
that mount point simply by checking the "Enable /etc/fstab mounting" option. Mount table entries in /etc/fstab must have the "user" or
"owner" option set to grant this permission unless gkrellm is run as root. For example, if you run gkrellm as a normal user and you want
to be able to mount your floppy, your /etc/fstab could have either of:
/dev/fd0 /mnt/floppy ext2 user,noauto,rw,exec 0 0
/dev/fd0 /mnt/floppy ext2 user,defaults 0 0
If gkrellm is run as root or if you have sudo(1) permission to run the mount(8) commands, then a custom mount command can be entered into
the "mount command" entry box. A umount(8) command must also be entered if you choose this method. Example mount and umount entries using
sudo:
sudo /bin/mount -t msdos /dev/fd0 /mnt/A
sudo /bin/umount /mnt/A
Notes: the mount point specified in a custom mount command (/mnt/A in this example) must be the same as entered in the "Mount Point" entry.
Also, you should have the NOPASSWD option set in /etc/sudoers for this.
File system monitors can be created as primary (always visible) or secondary which can be hidden and then shown when they are of interest.
For example, you might make primary file system monitors for root, home, or user so they will be always visible, but make secondary moni-
tors for less frequently used mount points such as floppy, zip, backup partitions, foreign file system types, etc. Secondary FS monitors
can also be configured to always be visible if they are mounted by checking the "Show if mounted" option. Using this feature you can show
the secondary group, mount a file system, and have that FS monitor remain visible even when the secondary group is hidden. A standard
cdrom mount will show as 100% full but a monitor for it could be created with mounting enabled just to have the mount/umount convenience.
When the "Ejectable" option is selected for a file system, an eject button will appear when the mouse enters the file system panel. If you
are not using /etc/fstab mounting, a device file to eject will also need to be entered. Systems may have varying levels of support for
this feature ranging from none or basic using an ioctl() to full support using an eject command to eject all its supported devices. Linux
and NetBSD use the "eject" command while FreeBSD uses the "cdcontrol" command, so be sure these commands are installed. Most eject com-
mands will also support closing a CDROM tray. If they do, you will be able to access this function by right clicking the eject button.
Mail Monitor
Checks your mailboxes for unread mail. A mail reading program (MUA) can be executed with a left mouse click on the mail monitor panel but-
ton, and a mail notify (play a sound) program such as esdplay or artsplay can be executed whenever the new mail count increases. The mail
panel envelope decal may also be clicked to force an immediate mail check at any time.
gkrellm is capable of checking mail from local mailbox types mbox, MH, and maildir, and from remote mailbox types POP3 and IMAP.
POP3 and IMAP checking can use non-standard port numbers and password authentication protocols APOP (for POP3 only) and CRAM-MD5 may be
selected as long as your mail server supports them.
Before internal POP3 and IMAP checking was added, an external mail fetch/check program could be set up to be executed periodically to down-
load or check remote POP3 or IMAP mail. This method is still available and must be used if you want gkrellm to be able to download remote
mail to local mailboxes because the builtin checking functions cannot download.
Battery Monitor
This meter will be available if a battery exists and will show battery percentage life remaining. A decal indicates if AC line is con-
nected or if the battery is in use. If the data is available, time remaining may be displayed as well as the percentage battery level. If
the time remaining is not available or is inaccurate, the Estimate Time option may be selected to display a battery time to run or time to
charge which is calculated based on the current battery percent level, user supplied typical battery times, and a default linear extrapola-
tion model. For charging, an exponential charge model may be selected.
A battery low level warning and alarm alert may be set. If battery time is not available from the OS and the estimate time mode is not
set, the alert units will be battery percent level. Otherwise the alert units will be battery time left in minutes. If OS battery time is
not available and the estimate time mode is set when an alert is created, the alert will have units of time left in minutes and the alert
will automatically be destroyed if the estimate time option is subsequently turned off.
CPU/Motherboard Sensors - Temperature, Voltages, and Fan RPM
For sensor monitoring on Linux, you must have lm_sensor modules installed in your running kernel which is beyond the scope of this README,
so see http://www2.lm-sensors.nu/~lm78/ for information. Sensor data is read from /proc/sys/dev/sensors and there is no linking to the
lm_sensor libraries.
Similarly, Windows requires a MBM install: http://mbm.livewiredev.com/.
FreeBSD and NetBSD provide builtin sensor reporting for some sensor chips. NetBSD uses the envsys(4) interface and sensors reading is
automatically enabled if you have either a lm(4) or viaenv(4) chip configured in your kernel.
Temperature and fan sensor displays may be optionally located on the CPU or Proc panels to save some vertical space while voltages are
always displayed on their own panel. If you set up to monitor both a temperature and a fan on a single CPU or Proc panel, they can be dis-
played optionally as an alternating single display or as separate displays. If separate, the fan display will replace the panel label.
The configuration for this is under the CPU and Proc config pages.
In the Setup page for the Sensors config you also enter any correction factors and offsets for each of the sensors you are monitoring. For
Linux, default values are automatically provided for many sensor chips, but if they are not correct you should review the lm_sensor docu-
mentation. See below for an explanation of converting lm_sensor compute lines to gkrellm correction factors and offsets. For Windows, MBM
internally handles the sensor corrections and no config entries should be required.
Note for NetBSD users:
The current implementation of the sensor reading under NetBSD opens /dev/sysmon and never closes it. Since that device does not sup-
port concurrent accesses, you won't be able to run other apps such as envstat(8) while GKrellM is running. This might change if
this happens to be an issue.
The reasons for this choice are a) efficiency (though it might be possible to open/close /dev/sysmon each time a reading is needed
without major performance issue) and b) as of october 2001, there's a bug in the envsys(4) driver which sometimes causes deadlocks
when processes try to access simultaneoulsy /dev/sysmon (see NetBSD PR#14368). A (quick and dirty) workaround for this is to monop-
olize the driver :)
CPU/Motherboard Temperatures
Most modern motherboards will not require setting temperature correction factors and offsets other than the defaults. However, for lm_sen-
sors it is necessary to have a correct "set sensor" line in /etc/sensors.conf if the temperature sensor type is other than the default
thermistor.
On the other hand, some motherboards may need temperature calibration by setting a correction factor and offset for each temperature sensor
because of factors such as variations in physical thermistor contact with the CPU. Unfortunately, this calibration may not be practical or
physically possible because it requires that somehow you can get a real CPU temperature reading. So, the calibration discussion which fol-
lows should probably be considered an academic exercise that might give you some good (or bad) ideas.
Anyway, to do this calibration, take two real CPU temperature readings corresponding to two sensor reported readings. To get the real
readings, you can trust that your motherboard manufacturer has done this calibration and is reporting accurate temperatures in the bios, or
you can put a temperature probe directly on your CPU case (and here is where things get impractical).
Here is a hypothetical CPU calibration procedure. Make sure gkrellm is configured with default factors of 1.0 and offsets of 0 and is
reporting temperatures in centigrade:
1 o Power on the machine and read a real temperature T1 from the bios or a temperature probe. If reading from the bios, proceed with
booting the OS. Now record a sensor temperature S1 as reported by gkrellm.
2 o Change the room temperature environment (turn off your AC or change computer fan exhaust speed). Now repeat step 1, this time
recording a real temperature T2 and gkrellm reported sensor temperature S2.
3 o Now you can calculate the correction factor and offset you need to enter into the Sensor configuration tab:
From:
s - S1 t - T1
------ = ------
S2 - S1 T2 - T1
T2 - T1 S2*T1 - S1*T2
t = s * ------- + -------------
S2 - S1 S2 - S1
So:
T2 - T1 S2*T1 - S1*T2
factor = ------- offset = -------------
S2 - S1 S2 - S1
Voltage Sensor Corrections
You need to read this section only if you think the default voltage correction factors and offsets are incorrect. For Linux and lm_sensors
this would be if gkrellm does not know about your particular sensor chip. For MBM with Windows, the default values should be correct.
Motherboard voltage measurements are made by a variety of sensor chips which are capable of measuring a small positive voltage. GKrellM
can display these voltage values and can apply a correction factor, offset, and for the negative voltages of some chips (lm80), a level
shifting reference voltage to the displayed voltage. There are four cases to consider:
1 o Low valued positive voltages may be directly connected to the input pins of the sensor chip and therefore need no correction. For
these, the correction factor should be 1.0 and the offset should be 0.
2 o Higher valued positive voltages will be connected to the input pins of the sensor chip through a 2 resistor attenuation circuit.
For these, the correction factor will be a ratio of the resistor values and the offset will be 0.
3 o Negative voltages will be connected to the input pins of the sensor through a 2 resistor attenuation circuit with one of the resis-
tors connected to a positive voltage to effect a voltage level shift. For these (lm80), the correction factor and offset will be
ratios of the resistor values, and a reference voltage must be used.
4 o Some sensor chips (w83782, lm78) are designed to handle negative inputs without requiring an input resistor connected to a voltage
reference. For these, there will be a correction factor and a possible offset.
For cases 2 and 3, the sensor chip input network looks like:
Vs o----///---o-------------o Vin
R1 |
o--///--o Vref
R2
where,
Vs is the motherboard voltage under measurment
Vin is the voltage at the input pin of the sensor chip and therefore is the voltage reading that will need correction.
Vref is a level shifting voltage reference. For case 2, Vref is ground or zero. For case 3, Vref will be one of the positive
motherboard voltages.
The problem then is to compute correction factors and offsets as a function of R1 and R2 so that GKrellM can display a computed motherboard
voltage Vs as a function of a measured voltage Vin.
Since sensor chip input pins are high impedance, current into the pins may be assumed to be zero. In that case, the current through R1
equals current through R2, and we have:
(Vs - Vin)/R1 = (Vin - Vref)/R2
Solving for Vs as a function of Vin:
Vs = Vin * (1 + R1/R2) - (R1/R2) * Vref
So, the correction factor is: 1 + R1/R2
the correction offset is: - (R1/R2)
Vref is specified in the config separately from
the offset (for chips that need it).
Fortunately there seems to be a standard set of resistor values used for the various sensor chips which are documented in the lm_sensor
documentation. The GKrellM sensor corrections are similar to the compute lines you find with lm_sensors, with the difference that lm_sen-
sors has an expression evaluator which does not require that compute lines be simplified to the single factor and offset required by
GKrellM. But you can easily calculate the factor and offset. For example, this lm_sensor compute line for a case 2 voltage:
compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1)
yields a correction factor of ((6.8/10)+1) = 1.68 and an offset of zero.
Note that the second compute line expression is not relevant in GKrellM because there is never any need to invert the voltage reading cal-
culation. Also, the compute line '@' symbol represents the Vin voltage.
A more complicated compute line for a case 3 voltage:
compute in5 (160/35.7)*(@ - in0) + @, ...
can be rewritten:
compute in5 (1 + 160/35.7)*@ - (160/35.7)*in0, ...
so the correction factor is (1 + 160/35.7) = 5.48
and the correction offset is -(160/35.7) = -4.48
and the voltage reference Vref is in0
Here is a table of correction factors and offsets based on some typical compute line entries from /etc/sensors.conf:
Compute line Factor Offset Vref
-------------------------------------------------
lm80 in0 (24/14.7 + 1) * @ 2.633 0 -
in2 (22.1/30 + 1) * @ 1.737 0 -
in3 (2.8/1.9) * @ 1.474 0 -
in4 (160/30.1 + 1) * @ 6.316 0 -
in5 (160/35.7)*(@-in0) + @ 5.482 -4.482 in0
in6 (36/16.2)*(@-in0) + @ 3.222 -2.222 in0
LM78 in3 ((6.8/10)+1)*@ 1.68 0 -
in4 ((28/10)+1)*@ 3.8 0 -
in5 -(210/60.4)*@ -3.477 0 -
in6 -(90.9/60.4)*@ -1.505 0 -
w83782 in5 (5.14 * @) - 14.91 5.14 -14.91 -
in6 (3.14 * @) - 7.71 3.14 -7.71 -
Command launching
Many monitors can be set up to launch a command when you click on the monitor label. When a command is configured for a monitor, its label
is converted into a button which becomes visible when the mouse enters the panel or meter area of the label.
You can use the command launching feature to run commands related to monitoring functions, or you may use it to have a convenient launch
for any command. Since gkrellm is usually made sticky, you can have easy access to several frequently used commands from any desktop.
This is intended to be a convenience and a way to maximize utilization of screen real estate and not a replacement for more full featured
command launching from desktops such as Gnome or KDE or others. Some launch ideas for some monitors could be:
calendar:
gnomecal, evolution, or ical
CPU: xterm -e top or gps or gtop
inet: gftp or xterm -e ftpwho
net: mozilla, galeon, skipstone, or xterm -e slrn -C-
And so on... Tooltips can be set up for these commands.
Alerts
The sensor and Battery monitors can have alerts configured to give warnings and alarms for data readings which range outside of config-
urable limits. A warning or alarm consists of an attention grabbing decal appearing and an optional command being executed.
Additionally, if you have the gvoice plugin and the ViaVoice libraries from IBM installed, a voice alert may be configured to get your
attention.
THEMES
A theme is a directory containing image files and a gkrellmrc configuration file. The directory should be installed as a subdirectory
under your ~/.gkrellm2/themes directory or under /usr/local/share/gkrellm2/themes. Themes for gkrellm can be downloaded from
http://www.muhri.net and once untarred can be selected from the Themes configuration tab.
gkrellm also searches /usr/share/gkrellm2/themes for any system wide themes installed as part of a distribution. Finally, a theme you sim-
ply want to check out can be untarred anywhere and used by running:
gkrellm -t path_to_theme
If you are interested in writing a theme, go to the Themes page at http://www.gkrellm.net and there you will find a Theme making reference.
PLUGINS
gkrellm tries to load all plugins (shared object files ending in .so) it finds in your plugin directory ~/.gkrellm2/plugins. The directo-
ries /usr/local/lib/gkrellm2/plugins and /usr/lib/gkrellm2/plugins are also searched for plugins to install.
Some plugins may be available only as source files and they will have to be compiled before installation. There should be instructions for
doing this with each plugin that comes in source form.
If you are interested in writing a plugin, go to the Plugins page at http://www.gkrellm.net and there you will find a Plugin programmers
reference.
CLIENT
/SERVER
When a local gkrellm runs in client mode and connects to a remote gkrellmd server all builtin monitors collect their data from the server.
However, the client gkrellm process is running on the local machine, so any enabled plugins will run in the local context (Flynn is an
exception to this since it derives its data from the builtin CPU monitor). Also, any command launching will run commands on the local
machine.
Finally, at this time there is no support for file system mounting and mailbox checking on the machine where the gkrellmd server is run-
ning.
