Overview

Multiload-ng is a modern graphical system monitor. It's a near-complete rewrite of the good old GNOME multiload applet, that aims to support every existing panel.

It supports the following panels:

XFCE (xfce4-panel) LXDE (lxpanel) MATE (mate-panel) Ubuntu Unity (through libappindicator) Every panel with support for Application Indicators System tray (virtually any panel with a systray, in particular those without external plugins support, like tint2) Standalone (has its own window, not embedded in any panel) Avant Window Navigator (EXPERIMENTAL)

Multiload-ng can be built with GTK2 and GTK3, so can be embedded within GTK2/GTK3 builds of all the panels above.
