# Memory Load Applet

Copyright © 2000 by Telsa Gwynne and Eric Baudais

# The memory load applet

The `memload_applet` is a small monitor applet which sits in your panel and tells you how much memory is being used.

## Usage

You don't need to do anything to this applet. It will sit and run in your panel. Various options to alter its display are available.

Figure 1. MEM Load Applet

The applet shows four different uses of memory:

Free

  Free memory is memory which is not being used by any program. The default colour is green.

Buffers

  Buffers hold data which has not yet been written to the disk. They also hold data which has been recently read from the disk, keeping it around in case it is needed again. The default colour is grey.

Shared memory

  Shared memory is memory which more than one program is using. This is a very common thing to do on UNIX systems. Many GNOME programs use a lot of shared memory, which cuts down on the total memory used. The default colour is yellow.

Other

  Memory being used in other ways is shown in this category. The default colour is a greenish-yellow.

## Right-Click Pop-Up Menu Items

In addition to the standard menu items, the right-click pop-up menu has the following items:

Default Properties...

  This opens the `multiload_applet dialogue box` described below which allows you to alter the default properties of this and related monitor applets.

Properties...

  This opens the `multiload_applet dialogue box` described below which affects only the `memload_applet` properties.

Run gtop...

  This option will run the gtop which starts up the GNOME System Monitor. `gtop` gives a much more detailed look at your system and what's happening on it.

## Properties

Figure 2. Default Properties Dialog

Like several of the monitor applets, `memload_applet` has two ways of setting preferences. You can make changes that affect any of this group of applets (`cpuload_applet`, `memload_applet`, `swapload_applet`, `netload_applet` and `loadavg_applet`) in one large dialogue box. This is useful if you run one or more of them. These are the settings used by default. They are reached from the Default Properties... menu item.

Figure 3. Greyed Out Properties Dialog

Or you can change just the properties for `memload_applet`. This is useful for when you only use `memload_applet` or want to try new combinations out. It is reached from the Properties menu item.

| If you use the Properties... menu item and edit the preferences for just this applet, you must uncheck the Use default properties checkbox before you can alter any settings.

Figure 4. MEM Load Properties Dialog

The changes you can make to the properties are three:

Colours

  You can alter the colours used for the different categories of memory the applet displays by clicking on the colour boxes. This invokes the GNOME colour wheel.

Speed

  You can alter the speed that the graph proceeds with this. It is measured in milliseconds. The default value is 500.

Size

  You can alter the size of the applet with this. It is measured in pixels. The default value is 40, and the range is from 1 pixel to whatever you like. In a vertical panel, this refers to the height. In a horizontal panel, it refers to the width.

## Known Bugs and Limitations

Resizing and then altering the panel orientation can still cause intermittent problems, although they now fix themselves after a short period.
