The CPU and memory usage applet
The cpumemusage_applet is a small monitor applet which sits in your panel and tells you about your machine's use of CPU, memory and swap. To add this applet to a Panel, right-click on the Panel and choose Panel->Add to panel->Applet->Monitors->CPU/MEM usage.
Usage
You don't need to do anything to this applet. It will sit and run in your panel.
The applet shows three bar charts, for CPU, memory and swap space. If your panel is horizontal, the top bar is CPU, the middle is memory, and the bottom is swap. If your panel is vertical, the left bar is CPU, the middle is memory, and the right is swap.
- CPU
Three colours are used here. Yellow is used for CPU activity which does not need the kernel. Grey is used for CPU activity by programs talking to the kernel (typically, lots of I/O such as moving things between memory and disk). Black is the background and represents unused CPU.
- Memory
Four colours are used here. Yellow is used for shared memory (memory more than one program is using). Grey is used for buffer use (memory containing data not yet written to disk). The greenish-yellow is used for other memory use. Green represents unused memory.
- Swap
Two colours are used here. Red is used for swap space in use. Green is for unused swap. Swap is a section of the hard-drive where the kernel puts parts of programs which are not currently being used so that it can retrieve them easily when it needs to.
