xstatbar

News 12-May-2010: xstatbar has been updated. See new version (0.4p0) below. Works now on i386 single core machines (Thanks Tobias).

Description

xstatbar is a simple system monitor that shows various stats jn an X window that's immovable and not part of your tab-order. I built it to go with tiling window managers like scrotwm and xmonad where you can configure a small region of the screen as "off-limits" for windows.

xstatbar was written on OpenBSD and probably has a great-many OpenBSD-isms in it. None the less, the code is rather simple and easily modified.

Features

The stats shown are:

CPU graph for each CPU/core, showing the time spent in each state (user, nice, system, interrupt, idle) for the last 60 seconds.
Current percentage of time in each CPU state.
Memory graph showing amount of memory active, allocated, and free for the last 60 seconds.
The current amount of memory active, allocated, and free, as well as swap usage (if any swap is used).
The number of active and total processes
Battery info, including percent charge remaining and estimated time remaining.
Volume, for both left and right outputs.
Date and time.

Screenshots

Here's a simple screenshot (warning: the file is big... scaling it down distorts the display). Click it to enlarge. xstatbar is at the top.

That clock is generated by the following command in my .xinitrc file

      /usr/local/bin/xstatbar &

Shameless plug...
In this screenshot, you'll notice my vitunes program in the bottom-right window.
