Also there is nice real time graph on background.
Press Show Panel button to enable dashboard. You can drag floating window over the screen or double tap to open settings. See video and screen-shots for details.

This application allows you to:
- Easy diagnostic problem processes that consume resources excessively.
- With Cool Tool you can monitor full-screen applications (games, video players, browsers).
- Monitor your Internet traffic without closing the browser window.
- Make your battery level always visible, with accurate percentage scale.
- Monitor how good your CPU governor switches between CPU frequencies in idle/stresses

Customize the appearance of the panel using color picker dialogs. Also you can adjust transparency and size of the panel in Sliders section.
Tons of gauges could drain your battery very quickly. Uncheck the features that you do not need. Btw, Cool Tool went to sleep and do not draw anything when your display turns off. It is for power save.

ps: If you want to help me localize app into your native language, let me know.

    This has every statistical data you need. And is highly customisable. Will show details in notification area if u like to have it there. Or anywhere else too.
