Graph information
Shows the number of different IRQs received by the kernel. High disk or network traffic can cause a high number of interrupts (with good hardware and drivers this will be less so). Sudden high interrupt activity with no associated higher system activity is not normal.

Zooming is very easy, it's done in 3 clicks (regular clicks, no drag&drop):
- Click to define the start of zoom.
- Click to define the ending of zoom.
- Refresh.
You can use the interactive form too.
