Perfgraph
by Márton Anka

CPU / memory / network / hardware monitor. It is implemented as an Explorer toolbar so it does not necessarily take up space from your desktop.

A quick overview of its features:

• CPU utilization display for up to 8 cores
• Memory utilization indicator
• Network throughput monitoring via SNMP
• Network performance & reliability monitoring by pinging remote hosts
• Hardware monitoring
  o CPU temperatures
  o Chipset temperatures & fan speeds
  o HDD temperature
  o Gigabyte Odin PSU support (voltage, current, power, etc.)
• Very lightweight: minimal CPU and memory utilization

Perfgraph will run on both x86 and x64 versions of Windows XP or later.

Perfgraph is an extension to the Taskbar and runs within the explorer.exe process. It will monitor the activities you select, and draw pretty graphs with a user-configurable refresh speed - adjustable between .02 seconds and one hour. It is extremely versatile. Perfgraph will use Explorer's built-in serialization features, which means that your settings and graph layouts are only saved when you close Explorer cleanly, for example by logging off.

Some notes on the website:

Microsoft disabled dragging toolbars from the Taskbar to the desktop on Vista, but you can still achieve the same result with a bit of trickery:

• First, create an empty folder on your desktop.
• Drag this folder to the very ednge of your screen. It will turn into a toolbar, and right-clicking it will allow you to call up Perfgraph from the Toolbars menu.
• Once Perfgraph is visible, right-click it and uncheck "New Folder" (or whatever your folder was called) in the Toolbars menu.
• You can then freely drag the Perfgraph-only toolbar around the screen.
• Note that to undock a toolbar from the edge of the screen on Vista, you can't just grab it anywhere in its nonclient area, you need to move your mouse to the very edge of the screen to be able to start the drag operation.
