DESCRIPTION
The asmem is a X11 application that acts as a memory utilization moni‐
tor. It shows the current amount of memory and swap space, the free
amounts of those, and the bars representing graphically the different
types of memory.
The display consists of two areas. The one above shows utilization of
the memory, the one below - the utilization of the swap space. Each
area contains a graphical bar that represents the percentage of the
occupied space. For the memory utilization there are three bars:
user/system memory used, buffer memory and cache memory. For the swap
space only one bar showing the used space. Above each bar is the total
amount of space, below the bar - the available space in kbytes and per‐
cents. If the memory amount is above 999999 kbytes the displays
switches to Mbytes instead of kbytes.
It is possible to force the display into Mbytes. You can also ask asmem
to display the occupied memory amounts and percentages rather than
those still available.
CONFIGURATION OPTIONS-h or -H
Prints a short description and usage message.
-V
Version control. Prints out the version of the program.
-position [+|-]x[+|-]y
Displays the window at the specified location on the screen.
This works like the standard X Windows geometry option. (See
XParseGeometry (3x)).
-iconic
Starts the asmem application in the iconized mode. The icon has
the same appearance with the main window. When this option is
given, the -position refers to the position of the icon window
as well as the main window.
-withdrawn
Starts the asmem application in the withdrawn mode. This option
is necessary to be able to dock the asmem in the WindowMaker
dock. When this option is given, the -position refers to the
position of the icon window as well as the main window. asmem
ignores the -iconic option when started in withdrawn mode.
-standout
This changes the appearance of the asmem display from "pushed-
in" to "popped-out". The first is the default look. The
"popped-out" applets look much better in WindowMaker's dock
according to some opinions. Give it a try in any case.
-used
By default asmem displays the amount of memory or swap space
still left unused. This switch tells asmem to display the
amounts of memory and swap space already in use. This switch
affects the percentages displayed in accordance.
-asis
Uses an alternative number for the display of the free memory.
Or, rather, by default an alternative amount is used. When this
switch is specified, the applet displays the amount of memory
free as reported by the /proc/meminfo. Sometimes this is not
really helpful since the occupied memory includes the file sys‐
tem cache and the buffers space. When this switch is not speci‐
fied asmem will add the cache space and the buffer space to the
amount of the actual free memory since both of those may be dis‐
carded by the OS to free up some memory for the programs.
-free
Exactly the same as -asis. Provided for backward compatibility.
Obsolete. Do not use. Use -asis instead.
-mb
Force the display in MBytes instead of kilobytes even if the
numbers would fit into the window.
-u <update rate>
Changes the polling rate for updating the memory utilization
information. The update rate is specified in seconds. The value
of 1 is the minimum. Default value is 1 second.
-dev <device>
The device that should be polled for the memory utilization
information. On Linux, this defaults to /proc/meminfo
-display <name>
The name of the display to start the window in. It works just
as X Windows display option.
-bg <color>
Changes the color of the background of the applet. Default
colour is #303030.
-fg <color>
Changes the color of the foreground of the applet. Default
colour is #20b2aa.
-memory <color>
Changes the color of the bar that represents the used memory
amount. Default colour is #4141d7.
-buffer <color>
Changes the color of the bar that represents the memory used for
buffers. Default colour is #aa80aa.
-cache <color>
Changes the color of the bar that represents the memory used for
caching. Default colour is #bebebe.
-swap <color>
Changes the color of the bar that represents the swap space uti‐
lization level. Default colour is #ffa649.
INVOCATIONasmem can be called in different ways. The most common invocation is
the command line:
user@host[1]% asmem-bg blue -fg white &
Another way to call asmem is from the window manager:
*Wharf "asmem" nil Swallow "asmem" asmem &
This line, when placed in the wharf file in the user's Afterstep con‐
figuration directory will cause asmem to be a button on the Wharf (1)
button bar under the afterstep (1) window manager.
If you run WindowMaker then you should use the "-withdrawn" option:
user@host[1]% asmem-withdrawn -standout &
and then drag the icon to the dock.
BUGS
My programs do not have bugs, they just develop random features ;-)
Well, there are limitations. All the strings for the color names, dis‐
play name, and the geometry have the length limit of 50 characters
(terminating zero included). The string copying routine cuts the names
that are longer.
