Conky is a free, light-weight system monitor for X, that displays any information on your desktop. Conky is licensed under the GPL and runs on Linux and BSD.
Conky has more than 250 built in objects, including support for:
- a plethora of OS stats (uname, uptime, CPU usage, mem usage, disk usage, “top” like process stats, and network monitoring just to name a few)
- built in IMAP and POP3 support
- built in support for many popular music players (MPD, XMMS2, BMPx, Audacious)… and much much more.
Conky can display this info either as text, or using simple progress bars and graph widgets, with different fonts and colours.
